Low Profile Socket Sex Bolts (Imperial Sizes)

  • Host a smooth thin head with a standard socket drive.
  • Male screw fastens into internally threaded female barrel nut (sex bolt).
  • Sleek and unobtrusive, ideal for architectural applications.

Socket barrel nuts and mating low profile shoulder screws with a smooth thin head with a standard socket drive. They are ideal for use in projects where aesthetic display and conformity are essential – as the matching heads give a sleek, unobtrusive and polished finish.

The nut has a smooth barrel under the head, while the mating screw has a shoulder under the head with the same outer diameter as the barrel nut, keeping a smooth sleek look throughout, whilst also providing additional supporting strength to the fixture.

The thin profile of the head is useful in applications where the material is too thin to countersunk and a concealed appearance is required. The larger diameter of the low profile head also spreads the load across a wider surface, providing a greater holding power in thinner material applications.

The low profile provides excellent strength and versatility, enabling use in a variety of industries from light-duty furniture and staircasing applications to more heavy-duty industrial construction and commercial projects.

The barrel nuts are sometimes referred to as sleeve nuts within the industry.

Available as standard in A4 Stainless Steel from Fastenright, provided 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.
