We manufacture stainless steel flat head phillips-drive screws in the 11 recorded sizes M1 to M14, cold headed, thread rolled, deburred and cleaned, and inspected against the drawing, for eyewear hinges, handheld electronics and miniature gearboxes, with the head and the thread formed on the same blank and every batch gauged before packing. Head diameter, recess depth, thread length and surface finish are made to your drawing, and the driver bit match is reviewed before production.
Shi Shi Tong supplies stainless steel flat head screws with a Phillips drive on a made-to-order basis. For this item the recorded configuration is Plain finish, full thread, a machine thread, right hand direction and metric, inch measurement, thread fit 6g. Any requirement outside the recorded configuration is reviewed against the drawing before the batch runs.
The table below is the specification recorded for this screw, not a catalogue of every size the factory can produce. Where a project needs a different head, drive, thread or finish, the part is reviewed as a drawing-based item.

Wire and bar are bought against the mill certificate: grade, heat number and standard are checked before forming, and the material report is kept with the production record.
A flat or countersunk head is conical underneath and sits flush with the joint surface once the matching countersink is cut. It leaves a smooth face after assembly and centres the screw in the hole.
The Phillips recess is a cross with tapered walls. The driver is meant to rise out of the recess once the target torque is reached, which limits over-tightening on assembly lines, at the cost of a smaller contact area than a six-lobe recess.
The recess or drive size is matched to the tool used on your line. State the driver size or the torque target on the drawing so the head and the drive are reviewed together with the head diameter.
A machine thread engages a pre-tapped hole or a nut rather than cutting its own path into the material. The mating thread has to be prepared to the same size and class, so the screw and the tapped hole are specified together.
The finish is plain: no plating and no additional coating. On stainless steel the corrosion resistance then comes from the alloy; on carbon steel it does not, and the environment has to be considered.
Salt-spray testing is recorded as customized, which means the test duration and the acceptance criterion are set with the order instead of being published as a fixed figure. Where a project specifies a duration, that duration becomes the inspection requirement for the batch.
Packing is recorded as plastic bag + carton. Parts are bagged before they go into the carton so the thread and the head are protected in transit.
The joints below are where these screws actually fail when the geometry is loose, so each paragraph names the failure, what it costs and the dimension we hold:
Eyewear hinges and frames. On screws joining the hinge barrel to the front and the temple of a pair of glasses, the shank snaps at the thread run-out after a few hundred folding cycles. The frame comes back as a warranty return and the optician has to refit or replace it, because the thread run-out sits inside the hinge barrel where bending stress concentrates. We control it at the source: the run-out position and the shank diameter are set on the drawing so the unthreaded length stays inside the barrel.
Handheld electronics and wearables. On fixings inside a phone, camera or watch housing that is assembled at a torque-controlled station, the recess strips and the driver spins, so the housing cannot be reopened for service. The whole module is scrapped at the service centre instead of being repaired, because recess depth is shallow against the bit engagement for the torque the station applies. We control it at the source: recess depth, recess width and the driver bit size are reviewed together against the assembly torque.
Miniature gearboxes and sensors. On screws retaining end plates and sensor brackets on small drives, the thread strips in an aluminium or zinc-alloy housing during assembly. The housing is reworked or scrapped and the assembly line stops, because thread engagement length is shorter than the drawing calls for in the softer alloy. We control it at the source: thread length and the minor diameter are controlled to the drawing so engagement is reached without over-tapping.
The size field recorded for this item is M1 M2 M3 M4 M5 M6 M7 M8 M9 M10 M14. Sizes inside that range are quoted against the drawing, because the head diameter, the head height and the length are set per part rather than taken from one stock list.
Where a length or a diameter outside the recorded range is needed, the part is treated as a drawing-based item and the tooling is reviewed before quoting.
Wire and bar are bought against the mill certificate: grade, heat number and standard are checked before forming, and the material report is kept with the production record.
Manufacturing since 1998. Parts are produced to your drawing or sample; overall range M0.8-M16 diameter and 0.4-2000 mm length, each subject to material, structure and process review.
Have a complete production process. Ensure product dimensional tolerances and appearance.
The route is planned from the approved drawing rather than taken from a stock list:
Inspection follows the features that decide whether the screw assembles: the head, the drive, the thread and the surface.
Results are recorded per batch so a repeat order can be compared with the first delivery.
ISO 9001:2015 Quality Management System Certification and an SGS testing report are the two documents stated for this product. Material reports for the raw wire are available with the shipment.

Fasteners are bought by people who have to make a line run again next quarter, so the order history is part of the specification.
