A2 70 Hex Head Bolt
While grade 2 is one of the most popular grades of alloy, the Grade A2 stainless steel fasteners exhibit several important properties, which makes them very relevant across several industries. For instance, the demand for A2 70 Hex Head Bolt is ensured by demonstrating properties such as strong abrasion resistance and reliably low levels of distortion.

Since the alloy has good ductile and formability features, producing threads on the A2 50 Stainless Steel Screw is relatively easy. Another important property of the A2 70 Bolts is their good resistance to corrosion at low and ambient temperatures. In fact, the Stainless Steel A2-80 Nuts has good mechanical strength even in cryogenic temperatures. Furthermore, the high level of hardness in amalgamation with the consistent dimensional stability is why the A2-70 g304 Studs exhibits good resistance to wear & tear as well.
