Hex Bolts & Setscrews Imperial Steel

Hex bolts have hexagonal heads and machine threads for use with a nut or in a tapped hole.

Allfix feature a huge range of bolts in imperial threads such as:

  • BA
  • BSW
  • UNC
  • UNF
  • BSF
  • Diameters:

    • 1/4 BSF - 5/16 BSF(Imperial)
    • 1/4 UNC- 5/8 UNC (Imperial)
    • 1/4 UNF - 5/8 UNF (Imperial)
    • 3/8 BSW (Imperial)

    Our steel bolts & sets (self colour and zinc) are HT (high tensile) as standard - this is to grade 8.8

    A sets screw is fully threaded, and a bolt is part threaded.

    A set or bolt is an externally threaded fastener designed for insertion through holes in assembled parts, and is normally intended to be tightened or released by torquing a nut. A setscrew is merely a fully threaded bolt.

    Please note we measure the length of our hexagon headed bolts & sets from under the head to the end of the thread, rather than the total length including the head.

    If you require ROHS Compliant bolts or sets please state this in the special order comments form at the checkout page when ordering.
