ASTM A276 Type 316 Fasteners

ASTM A276 Type 316 is a material grade specification for cold-finished or hot-finished bars in 316 stainless steel, available in form of rounds, square, hexagons and other hot rolled extruded shapes. Boltport uses 316 bar stock to ASTM A276 specifications for manufacturing stainless steel 316 bolts, nuts, screws, studs, threaded rods, other fasteners and bar stock components for general engineering purposes.

ASTM A276 specification covers requirements such as chemical composition, mechanical properties, heat treatment and other supplementary requirements for 316 stainless steel round bars, square bars, hexagon bars and other extruded shapes.
