What Are Industrial Fasteners?
Industrial fasteners are the threaded components — bolts, nuts, screws, studs, threaded rods and anchors — that clamp, join and secure parts in machinery, vehicles, steel structures and buildings. They are specified by standard (DIN, ISO, ASTM, ANSI), material and grade, thread size, length and surface finish, and bought in bulk by distributors, OEM plants and contractors.
