Combi Head Sex Bolts

  • Features Truss Head Combination drive (standard slotted/Phillips drive)
  • Identical head diameter and drive provide “set” appearance.
  • Male shoulder and female barrel diameter are matched.
  • Barrel nuts also referred to as sleeve nuts.

Combi Head Sex Bolts are a two-piece fixing with one internally threaded female part and one male screw. The male screw can either be; a standard machine screw type or a shoulder screw where the shoulder section mirrors the same diameter as the female part outer diameter.

Both the male and the female parts have a truss head with identical dimensions ensuring aesthetic symmetry. This fixing is suitable for providing support to and fixing two objects together.

The combi drive enables the use of both a slotted screwdriver or a Phillips screw driver to assemble and remove.

Combi head barrel nuts can be purchased separately or with their mating machine screw or shoulder screw.

These fasteners can often be found within food processing equipment and marine environments, and offer an aesthetically pleasing, strong and quick assembled fixing solution to a range of applications.

Available from Fastenright as standard in Zinc plated Steel, and A2 and A4 Stainless Steel.

These screws are available in a range of barrel diameters, barrel lengths and screw lengths.

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