A small phillips head screw is a tiny screw with a countersunk head and a cross recess, driven with a PH driver and used where the head has to finish flush and the parts are too small for a socket. The one on this page is aluminum, anodized in six colours, with a self-tapping thread and a blunt flat tail.
Countersunk head. The underside is a cone, so the head pulls into the countersink and finishes level with the panel. On a small phillips head screw the cone is shallow, and the angle has to match the countersink or the head stands proud on one side.
Phillips recess. The cross centres the driver and cams out at a set torque, which protects a tiny screw from being over-driven. The recess is cut with a PH0 or PH1 punch depending on the size, and the bit that will be used on the line is the bit the recess is checked against.
Self-tapping thread and blunt tail. The thread forms its own path in a pilot hole, and the tail is flat rather than pointed. A blunt tail does not drill: it starts in a prepared hole, which is what keeps a tiny aluminum screw from splitting a thin panel or wandering off the mark.
Together these decide the fit: the head sits flush, the cross takes the driver, the thread holds in the pilot hole, and the anodized colour stays on the head through handling.
This small phillips head screw is formed from aluminum wire on a single-die header, thread rolled and anodized in batches by colour. The alloy comes from the drawing, and the wire lot stays traceable to the material certificate.
The countersunk head and the cross recess are formed in the die. On a head this small the recess takes most of the face, so the punch has to be centred or one arm of the cross ends up shallower and the driver cams out on that side.
The self-tapping thread is rolled before anodizing. The blunt tail is formed with the thread and left flat, so the screw starts in a pilot hole instead of trying to drill its own path through a thin cover.
Anodizing is the finish and the colour. The oxide grows out of the aluminum, and the dye goes into that layer before sealing, so purple, dark blue, light green, light blue, green and red parts all carry their colour in the metal rather than in a film on top.
Small phillips head screws of this type are quoted from M1.6 to M3 and in lengths up to 20 mm, with the head and the recess measured on the projector and the thread checked against the pilot hole. Where a long version is required, custom lengths up to 2,000 mm are subject to DFM review after drawing submission.
| Item | How it is defined | What we control |
|---|---|---|
| Head diameter and angle | The cone that matches the panel countersink | Checked on the projector on the first article |
| Head height | The depth the head sinks into the countersink | Measured from the bearing cone |
| Phillips recess | PH0 or PH1, sized to the driver | Checked with the PH bit and on the projector |
| Thread | Self-tapping thread to the drawing | Checked against the pilot hole on the first article |
| Tail | Blunt flat tail, not a drill point | Checked on the projector |
| Total length | From the top of the head to the tail | Datum stated on the drawing; measured on the shop plate |
Each size is quoted against the hole it goes into. The pilot hole diameter, the panel thickness and the thread pitch are reviewed together, because a screw that holds in one plastic boss will strip in another.
Head height is measured from the bearing cone, and the total length from the top of the head. The batch is checked on the features the process can drift on: recess depth, head angle and thread form, all read after anodizing.
The Phillips recess is the drive of a small phillips head screw, and on a tiny head it is also the feature with the least room. The cross has to be deep enough for the PH bit to engage without rocking, and shallow enough that the head does not open through the top face under torque.
The recess is checked with the bit that will be used on the line. A PH1 bit in a PH0 recess, or the reverse, rounds the cross before the screw seats, and on an anodized head the damage shows as bright aluminum at the corners.
The blunt tail is the other half of the joint. It does not drill, so the panel or boss needs a pilot hole sized to the thread: too small and the aluminum thread shears, too large and the screw spins without holding. The drawing states the hole, and the first article is driven into a sample of it.
Anodizing builds in the recess and on the thread by a few microns. Both are checked after the bath, because a coated recess that no longer takes the bit is a drive failure, not a cosmetic one.
This small phillips head screw is anodized in one of six colours: purple, dark blue, light green, light blue, green or red. The same route serves all six, with the dye and the sealing step changing, so a batch of each colour is produced to the same drawing and the same colour sample.
| Finish | How it protects | Effect on thread and recess | Typical use |
|---|---|---|---|
| Anodized purple | Oxide layer dyed and sealed | Build-up; bit and thread checked after | Colour-coded device hardware |
| Anodized blue / green | Oxide layer, dye colour varies | Same build-up; checked after | Colour-coded covers and panels |
| Anodized red | Oxide layer, red dye | Same build-up; checked after | Visible colour-coded screws |
| Clear anodized | Oxide layer, no dye | Same build-up; bit checked after | Parts that keep the metal look |
| Zinc plated (steel equivalent) | Sacrificial zinc layer | Build-up on thread; gauged after | Steel parts where colour is not required |
Colour is matched to an accepted sample under agreed light. Anodized batches shift with alloy, bath and dye lot, so a red small phillips head screw from one run can sit a shade away from the next, and the sample and the acceptance range are fixed before production.
Packing protects the heads and the recesses. Screws are packed by colour, in layers so the heads do not rub, and the label carries the batch, the alloy and the colour reference.
Three assemblies where small phillips head screws are chosen for the flush head and the colour, and what the screw has to do instead:
| Where it sits | The screw closes a cover on a hand-held device, where the head has to sit flush and the colour is part of the finish. |
| When it goes wrong | A head that stands proud catches on a pocket, and a recess that is too shallow cams out before the cover seats. |
| Why it happens | The housing is small, the screws are visible, and the cover is opened for service. |
| What we control | Head angle and recess checked, and the colour compared with the sample per batch. |
| Where it sits | The screw holds a thin cover into a pilot hole, where a flush head keeps the surface smooth. |
| When it goes wrong | A blunt tail that is pushed into a hole that is too small distorts the panel, and a thread that is too coarse strips in thin sheet. |
| Why it happens | The sheet is thin, the hole is prepared, and the screws are driven by hand at low torque. |
| What we control | Pilot hole and thread matched, and the head angle checked against the countersink. |
| Where it sits | The screw fixes a panel where the screws are colour-coded by function and the face stays flush. |
| When it goes wrong | A colour that is off the sample reads as a wrong panel, and an anodized recess that is tight slows the line. |
| Why it happens | The panels are painted or anodized, the screws are visible, and the joint is assembled once. |
| What we control | Colour approved on a sample, recess bit-checked after anodizing, and packing that protects the heads. |
Four reasons that matter on a small phillips head screw with an anodized finish, each tied to what the drawing has to prove:
|
Pilot hole and head angle reviewed together
The pilot hole, the thread pitch, the head angle and the colour reference are reviewed before the die is cut, so a screw that would strip or stand proud is raised with you first. Basis: Hole, head and colour reviewed before tooling. |
Headed, threaded and anodized in one flow
The head and recess are formed in the die, the thread is rolled, and the parts go to anodizing as a colour batch, so the recess and the thread come from the same run. Basis: Heading and anodizing recorded per colour batch. |
|
Recess checked with the PH bit
The recess is checked with the bit and the head on the projector after anodizing, so the part that passes is the part the driver engages. Basis: Recess and head measured in the anodized condition. |
First article to repeat production
The first article fixes the drawing revision, wire lot, die set and colour batch; repeat orders are compared against that record. Basis: First article and colour sample signed off before the batch. |
Shi Shi Tong forms these small screws on a single-die header: the countersunk head and the cross are struck in the die, the self-tapping thread is rolled, and the parts go to anodizing as colour batches. The first part of every run is measured on the head, checked with the PH bit and driven into a pilot-hole sample before the batch continues.
|
|
Between runs the die insert is changed to the drawing head and the recess punch to the PH size; the first parts go to the projector and the bit check before the run continues, and the setting is recorded. Anodized parts are checked again after the bath, so the record covers both the formed and the coloured condition.
What decides whether a small phillips head screw passes is not the colour alone: it is the head angle and height, the recess depth and size, the thread form and the tail. The inspection agreement covers those, and the criteria come from the drawing and the pilot hole.
Head angle and recess on the projector |
Thread form and pilot hole checked on the first article |
Hardness testing of the aluminum alloy |
Salt-spray testing of the anodized finish |
Each batch is recorded against the drawing revision: head and recess from the first article, the bit check, the thread driven into the pilot-hole sample, and the colour compared with the sample under agreed light. If a gauge or the colour check fails, the parts back to the last good setting are held and re-checked.
Where a third-party report is required for the alloy or the anodized finish, it is listed on the drawing so the paperwork ships with the parts, and the batch number on the label matches the record used for inspection.
Every shipment is traceable to the aluminum it was made from. The alloy, lot number and standard are recorded on the material certificate supplied with the parts, and the inspection records follow the criteria agreed on the drawing.

With each batch we supply the material certificate, the inspection record for the criteria on the drawing and, where it is listed, the third-party report for the alloy or the finish. The documents carry the drawing revision and the batch number, so the paperwork can be matched to the parts.
More than 8,678 customers in 89 countries and regions have ordered from Shi Shi Tong; 87% of orders come from repeat customers and 56% through referrals. Most projects follow the same route: drawing review, first-article approval, then batches checked against that sample. Colour-critical small screws are approved on a physical sample, so the shade is signed off under the light the customer uses. Buyers visit during the process to review samples and to see how the heads and colours are produced.

It is a tiny screw with a countersunk head and a Phillips cross recess, driven with a PH driver. This one is aluminum, anodized in six colours, with a self-tapping thread and a blunt flat tail.
A blunt tail starts in a prepared pilot hole instead of drilling its own path. That keeps a tiny aluminum screw from splitting a thin cover or wandering off the mark, and it suits plastic bosses and sheet-metal covers.
PH0 or PH1 depending on the size. The recess is checked with the bit that will be used on the line, after anodizing, because the oxide builds inside the cross by a few microns.
Small phillips head screws of this type are quoted from M1.6 to M3 and in lengths up to 20 mm. Where a long version is required, custom lengths up to 2,000 mm are subject to DFM review after drawing submission.
This page records six anodized colours: purple, dark blue, light green, light blue, green and red. Each colour is matched against an accepted sample, and the acceptance range is fixed before production.
