A4-70 Hex Bolt

A4 50 Stainless Steel Bolts, DIN976 A4-80 Stud Bolt Dimensions

A4 50 Stainless Steel Bolts are austenitic steel bolts which have high corrosion resistance. The A4-80 Stud Bolt is also austenitic but is used in low tensile strength applications with high corrosion resistance especially against acids. The ideal use of A4-70 Nut is in the chemical industry. The 316 Stainless Steel Bolts can be used with a balance of strength and corrosion resistance; they have higher strength than the A4 70 Bolt.

The A4 80 Bolt belongs to the A4 series and it is a part of SS 316 Bolts And Nuts which are corrosion resistant and stronger but still considered minimum tensile strength. Therefore the use of A4-80 Hex Nut and SS 316 Nut Bolt is mainly in chemical industries and in acidic environments where the A4 Stainless Steel Bolts can withstand much corrosion but not high strength. The 316 Stainless Steel J Bolts are a special type with a j shaped hook that can hold additional accessories and be tightened to another object with a bolt.
