High quality SS stud bolt, threaded rod and socket head cap screws exporter in India.
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.
