03Technical description

The headless socket set screw is an industrial fastener with Bristol or Allen drive, used in hidden fastening, set screws, shafts, pulleys and component adjustment. 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 a socket head cap screw because it remains embedded or flush, without protruding from the part. For this lot there are actual sizes such as 1 X 3 to 1/4 X 5/16, 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.

Installation recommendations

  • Confirm whether the required thread is UNC, UNF or metric before quoting; do not mix pitches even if the diameter looks similar.
  • Use a Bristol or Allen key in good condition and fully seated to avoid stripping the internal drive.
  • Verify that the length does not bottom out in blind holes and allows the correct bearing of the head or tip.
  • On stainless steel, avoid contamination with rusty tools and consider compatible lubrication to reduce galling.
  • When the joint is critical, define torque from the drawing, base material and project assembly procedure.

04Frequently asked questions

What is the price of the headless socket set screw?

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.

How does it differ from the closest related reference?

Compared with a socket head cap screw, this format works as a set screw and leaves no external head; it is chosen to secure shafts, pulleys or parts where the screw must remain hidden.

How is it installed or assembled correctly?

It is installed with a Bristol key or compatible tool, verifying thread pitch, available depth, head or tip bearing and torque defined by the joint design.

What material and thread does this reference have?

This page corresponds to carbon steel Grade 8 with UNC inch thread. The standard reference indicated for selection is UNC thread when applicable.

What sizes can I quote?

You can quote the sizes listed in the product technical table. If you need an unpublished length, confirm availability with the sales team.

Is it suitable for outdoor use or corrosive environments?

Carbon steel without specialized coating must be protected if it will be exposed to humidity, chemicals or weather.
