Shi Shi Tong supplies carbon steel pan head screws with a Torx Recesses drive on a made-to-order basis. For this item the recorded configuration is , a machine thread, right hand direction and metric measurement. 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.
Carbon steel is chosen where the strength and the cost of the part matter more than corrosion resistance. Because the base metal will rust once the surface is broken, the finish becomes part of the specification rather than an optional extra.
A pan head has a slightly domed top and a flat bearing face under the head. It spreads the clamping load over the joint surface instead of sitting flush in a countersink, which suits through-hole assembly where the head is allowed to stand proud.
The Torx recess uses six lobes instead of a cross. The driver contacts a larger area of the recess wall, so the same torque can be applied with less tendency for the bit to cam out and damage the 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.
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 head and the drive decide which joints the screw suits, not the catalogue page:
The size field recorded for this item is M2*5.8mm,Diameter 3.4mm. 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.
A complete production process holds the dimensional tolerances and the appearance of the part; the inspection scope is agreed with the drawing.
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.
