High Tensile Stainless Steel Bolts manufacturer in India accordance to F593c/ ASTM A276

Stainless steel nut bolt are designed to provide leak-free, cost saving solutions in instrumentation and power applications. The SS Nut Bolt are plated with silver, which prevents galling, which could occur due to fluctuations across a range of temperatures. Silver plating also extends the life of the fitting. The compounds used to produce coated stainless steel fasteners include silver, Black Oxide Brass, Automotive, Chromate, Cadmium and Phosphate. Other coating compounds that could be used for coating Self-drilling stainless steel fasteners are PTFE and Teflon. Stainless steel bolts and nuts can also be galvanized with Zinc, which forms a protective covering around the fasteners. Passivated stainless steel fasteners are have a high resistance to rust. Stainless steel fasteners is passivated by coating to remove free ions on its surface with the help of an acidic solution, thus preventing rusting.


Table of Content


The pressure rating for Stainless Steel Bolts is up to 60000 psi for high pressure fittings while its temperature rating goes up to 537°C or 1000°F. The materials used to make Stainless steel nut and bolt are SS 304 Bolts, 316 Stainless Steel Bolts , 316L, 309, 310, 317L, 321, 347, 409, 410, 420, 430, 446, 202 etc.A benefit of using polished stainless steel fasteners is its high resistance to corrosion & rust and are low maintenance. A novel innovation in the field is the introduction of Coloured stainless steel fasteners. A thin layer of coloured coating is applied on the fitting. The colour coating is known to be non-corrosive, UV resistant and hard wearing. These fittings come in bright colours like black, red, blue, brass, green and copper.

Heavy duty stainless steel snap fasteners are used in industries like Medical, Electronics, Energy Food Processing, Mining, Agricultural Automotive, Construction, Nuclear, Oil, Gas, Petroleum Transportation and Heavy Machinery Marine. Since Stainless steel marine fasteners show high resistance to corrosive fluids & to environmental conditions, they are find application in the manufacturing process of marine parts or fitting.We deal with major Stainless Steel Fasteners Manufacturers in India. You can find the Stainless steel fasteners price list here.

There are 2 types of Stainless Steel Fasteners manufactured by Siddhagiri, these are temporary fasteners and permanent fasteners.
