Stainless Steel 316 Fasteners are Industrial fasteners that provide good corrosion resistance and are made of a molybdenum-bearing austenitic grade of Stainless steel. They are very popular for better resistance to chlorides, sea water, chemicals, and extreme environments and these Stainless Steel 316 Bolts and Nuts used in industries like marine, off-shore, petrochemical, food, pharmaceutical, construction industries. This ASTM A193 Stainless Steel 316 Fastener provides durability, high strength and service life at higher temperatures.
Premium Quality Stainless Steel 316 Fasteners
We are engaged in manufacturing, supplying & exporting a wide range of industrial high quality Stainless Steel 316 Fasteners. Our fasteners can be supplied in the form of bolts, nuts, screws, washers, studs, threaded rods, anchor fasteners, socket head cap screws and also in custom form of fastening solution that are made to global ASTM, ASME, DIN, ISO and EN standards.
Our fastening components are manufactured in grade 316 stainless steel with Molybdenum which adds more resistance against corrosion than standard 304 stainless steel. Hence SS 316 fasteners for marine applications and chemical industries applications become popular across the globe.
Our fastening products are cold formed and machined to attain accurate dimensions with superior mechanical strengths and fine surface finish. We produce fasteners both in standard and customized requirements.
What are Stainless Steel 316 Fasteners?
Stainless steel 316 fasteners are any mechanical elements that are utilized to fasten, join or connect machinery and building parts within an industrial establishment. Made from UNS S31600 stainless steel material, these fasteners can withstand conditions of high corrosiveness — the fasteners provide a superior resistance to pitting, crevicular corrosion, oxidation and chloride attack.
They are composed of roughly 2-3% molybdenum which enables a superior defense to corrosion and makes SS 316 fasteners suitable for extreme industrial environments where stainless steel generally cannot perform.

- Exceptional corrosion resistance
- Excellent resistance to seawater exposure
- High temperature performance
- Superior durability and service life
- Hygienic and easy-to-clean surface
- Strong resistance to chemical attack
