Combi Head Sex Bolts

SKU: SB05 Category:

Combi Head Sex Bolts In Stock

Combi Head Sex Bolts are a two piece fixing with one female (internally threaded) part and one male screw. The male screw can be either standard machine screw type or a shoulder screw where the shoulder section mirrors the same diameter as the female part outer diameter. Both male and female parts have a truss head with identical dimensions ensuring aesthetic symmetry, and combi drive enabling the use of both slotted screwdriver or phillips screw driver to assemble and remove.

  • Truss Head combination drive (standard slotted / phillips drive)
  • Male screw fastens into internally threaded female barrel nut (sex bolt)
  • Identical head diameter and drive providing complete “set” appearance
  • Matched male shoulder and female barrel diameter (screws without shoulder are also available)

Combi head barrel nuts can be purchased separately or with their mating machine screw or shoulder screw. This fixing is suitable for providing support to and fixing two objects together. Steel zinc plated parts are commonly used in round or square metal tube applications, while 18-8 and 316 stainless steel combi sex bolts are commonly used in food processing equipment and marine environments respectively. These parts offer an aesthetic, strong and fast assembled fixing solution to many industries and applications.

Available in Steel Zinc Plate, A4-316 Stainless Steel and A2 18-8 Stainless steel. See stock size chart below.
