Hex Head Barrel Nuts

  • Internally threaded barrel nut
  • High torque and strong fixing
  • Installed with standard spanner or socket
  • Hex Head Barrel Nuts could also be known as Hex Head Sleeve Nuts

Hexagon Head Sex Bolts are an internally threaded female barrel nut with a smooth barrel, and no serrations under a standard hexagon head form.

The hex head is tightened using a standard spanner or socket drive, allowing high torque to be achieved whilst the barrel provides supporting strength to the overall fixing of the component, or multiple components that it is clamping together.

This type of fixing is suitable for fixing two objects together without a thread being required and makes the fixing practical and easy to assemble. When combined with hexagon head setscrews, which can be purchased separately, this fixing also provides an aesthetic connecting fastener symmetry.

Available from Fastenright in A2 Stainless Steel as standard.

Non-standard sizes and materials are available to order as specials, including custom parts made to drawings.
