Phillips Oversized Truss Head Barrel Nuts

  • Load Spread via Phillips Truss Head.
  • Serrations under head bite into the surface material.
  • Internally threaded barrel nut with a smooth barrel
  • Barrel nut often referred to as sleeve nut within the industry.

Truss Head Sex Bolts with an internally threaded barrel nut with a smooth barrel, meaning it has no knurling, and serrations under the large diameter head to provide extra grip.

The truss head of the barrel nut helps to distribute the load to a wider area, providing a similar function to that of a washer, whilst the serrations under the head provide a locking element by biting into the surface material, which is advantageous in applications that are prone to loosening.

This bolt is installed using a standard Phillips screw driver bit, allowing medium to high torque to be achieved, whilst the barrel of the hexagon sex bolt provides supporting strength to the fixing.

Available from Fastenright in A2 Stainless Steel, with a range of barrel diameters and lengths.

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