Stainless Steel Fasteners is also known as inox fasteners or inox steel. It is derived from the French word “inoxydable”. It is composed of minimum 10.5 % chromium. One example of non-magnetic fastener is Stainless Steel A2 Bolts (304, 18/8), itis an inox stainless steel bolts. In A2 bolts material chromium provides a corrosion and oxidation resistance; however, it can tarnish. Most common types of stainless-steel bolt are SS 304 bolts. SS 304 fasteners contains both chromium (18–20%) and nickel (8–10.5%) as the main non-iron constituents. Siddhgiri Tubes is government approved Stainless Steel Fasteners Manufacturers in India. We supply a various range of Stainless Steel nut bolt which are used for construction purposes in land, in water (rain water and fresh water) and other harsh environmental conditions.
