Phillips Oversized Truss Head Barrel Nuts

SKU: SB06 Category:

Phillips Oversized Truss Head Barrel Nuts / Sex Bolts In Stock

These truss head sex bolts feature an internally threaded barrel nut with a smooth barrel (without knurling) and serrations under the large diameter head for extra grip. In stock at Fastenright in stainless steel or steel chrome.

The truss head of the barrel nut helps distribute the load to a wider area, providing a similar function to that of a washer, while 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 or slight vibration. This fixing is installed using a standard phillips screw driver bit allowing medium to high torque do be achieved while the barrel of the hexagon sex bolt provides supporting strength to the overall fixing of the component(s).

  • Internally threaded barrel nut, smooth barrel
  • Male screw fastens into internally threaded female barrel nut (sex bolt)
  • Serrations under head bite into surface material to provide grip
  • Phillips truss head helps spread load

Available in A2 18-8 Stainless steel, with steel chrome available in 1/4″ diameter.
