Hex Head Screws

Hex Head Screws

Category : Screws

Hex Screws (also known as hex head screws) are simple screws with full hex head. Hex screws are produced in metric and imperial sizes. DIN 933 / ISO 4017 & ASME B18.2.3.1M are most standard dimensional specification used for manufacturing Hex Head Screws.

We offer hex head screws in coarse, fine threads with UNC, UNF and 8UN thread profile. BoltPort primarily manufactures and supply hex screws grades 4.6, 8.8, 10.9, 12.9 in high tensile while A2-50, A2-70, A2-80, A4-50, A4-70 & A4-80 in corrosion resistant stainless steel.
