About Socket Head Bolts
Socket Head Bolts also commonly known as Allen Bolts or Hexagon Socket Head Bolts are high-strength alloy fasteners, with a cylindrical head and an internal hexagonal drive. This design also enables tightening with high-torque with an Allen key or hex wrench which is why these are best suited to areas with limited space or to looks that are clean and flush.
These bolts come in plain headed or knurled heads so as to have better hand grip when constructing. At Jade Alloys, we manufacture socket head bolts in high-tensile alloys, stainless steel, and duplex steels. Our production covers both metric and imperial sizes with thread profiles including UNC, UNF, UN, and ISO metric. ASTM A574 serves as the primary material specification for high-strength socket head allen bolts.
