Stainless Steel Bolts

Stainless Steel Bolts is a type of mechanical fastener that is usually used with a nut or washer nut for connecting two or more parts. A bolted joint can be readily disassembled and reassembled; for this reason bolts or screw fasteners are used to a greater extent than any other type of mechanical fastener and have very important role in the development of mass-produced articles and steel structures. Our extensive range of high quality fastenings in A4 /316 stainless steel Bolts are specially suited to marine, swimming pool and other high corrosion applications.

Stainless Steel Bolts grades:

Stainless steels are used for their corrosion resistance, high-temperature strength, scaling resistance, and low-temperature toughness. These properties account for their extremely wide use in practically every industry. Austenitic Stainless Steels are designated by a 3 digit SAE Stainless Steel Grade beginning with the number 3 (e.g. 304, 316). Another common naming convention for Austenitic Stainless Steels are 18/8, 18/10, 18/0, etc. where the 18 refers to the % of Chromium and 8 to % of Nickel contained in the material.
