The socket head cap screw is an industrial fastener with Bristol or Allen drive, used in machinery joints, molds, light structures, equipment and industrial maintenance. At TECTUL it is offered in carbon steel Grade 8, UNC inch thread and UNC thread reference when applicable to the product design. Selection should start from the thread, usable length, head type and compatibility with the threaded part or existing nut. It differs from countersunk and button versions by its cylindrical head, larger bearing area and deeper key engagement. For this lot there are actual sizes such as 1 X 10 to 1.1/4 X 3, sold per unit. It is an option for maintenance, fabrication, equipment assembly, spare parts and assemblies where a precise, removable fastening with good tool access is required.

We dispatch to Bogotá, Medellín, Cali, Barranquilla and all of Colombia. Request a quote via WhatsApp for the socket head cap screw, indicating size, thread, material, quantity and whether you need equivalence with DIN, ISO or inch thread.
The price depends on the requested size, material, thread, standard and quantity. Send us the exact reference via WhatsApp and TECTUL will quote according to lot availability.
Compared with a headless socket set screw, this model leaves a bearing head for a removable joint; compared with a countersunk screw, it does not require machining a conical seat.
