The Bristol/Allen socket head cap screw is an industrial fastening element with Bristol or Allen drive, used in machinery joints, molds, light structures, equipment, and industrial maintenance. TECTUL offers it in zinc plated carbon steel class 8.8, metric thread, and DIN 912 reference when applicable to the product design. Selection must start from the thread, usable length, head type, and compatibility with the existing threaded part or nut. It differs from countersunk and button versions by its cylindrical head with greater bearing area and key depth. For this lot there are actual sizes such as 4 X 10 to 5 X 8, sold by unit. It is an option for maintenance, fabrication, equipment assembly, spare parts, and assemblies where precise, removable fastening with good tool access is required.

Compared with the headless Bristol screw, this model leaves a bearing head for a removable joint; compared with a countersunk screw, it does not require machining a conical seat.
It is installed with a Bristol/Allen key or compatible tool, verifying thread pitch, available depth, head or tip seating, and the torque defined by the joint design.
This page corresponds to zinc plated carbon steel class 8.8 with metric thread. The standard reference indicated for selection is DIN 912 when applicable.
You can quote the sizes listed in the product technical table. If you need an unpublished length, confirm availability with the sales team.
Zinc plating provides surface protection for indoor environments or moderate exposure; for high corrosion, stainless steel or specific coatings should be evaluated.
