03Technical description

The square head set screw is an industrial fastening element with Bristol or Allen drive, used in mechanical locking and adjustment with external drive. TECTUL offers it in carbon steel, UNC inch thread, and UNC thread 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 is not a Bristol/Allen set screw: it is tightened from the square head and used when adjustable thrust or fastening is required. For this lot there are actual sizes such as 1 X 3 to 1/4 X 1/2, 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.

Installation recommendations

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

04Frequently asked questions

What is the price?

The price depends on the size, material, thread, standard, and requested quantity. Send us the exact reference via WhatsApp and TECTUL will quote according to lot availability.

How does it differ from the closest sister reference?

Compared with the headless Bristol set screw, the square head set screw is handled externally with a wrench and is suitable when frequent adjustment is required.

How is it installed or mounted correctly?

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.

What material and thread does this reference have?

This page corresponds to carbon steel 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 If you need an unpublished length, confirm availability with the sales team.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?

Uncoated carbon steel must be protected if it will be exposed to moisture, chemicals, or weather.
