Stainless steel fasteners are known for their exceptional corrosion resistance and heat resistant properties. Stainless steel fasteners contain a minimum of 10.5% chromium which is fundamental in the resistance to corrosion. The chromium levels can be increased to help achieve a better resistance to corrosion. Other components like nickel, molybdenum and nitrogen can be added to increase corrosion resistance, resistance to pitting corrosion and mechanical strength respectively. Stainless steel fasteners are preferred not only for its high corrosion resistance levels but also for its other renowned properties like high-temperature strength, toughness in a number of environments and ductility. Stainless steel fasteners are high strength fasteners that are applicable in industries that require high-pressure like Hydrocarbon Industries & Refineries and Oil & Gas Exploration & Drilling.

We have a state of the art mill facilities access which runs at a full capacity due to export order overload. We have 3 heavy punch machines for shaping the bar. We also have threads machines to make NPT, BSPT & BSPP threads to the forging. Added to that we have in house testing facilities like spectro machine, PMI Machine, Mechanical test, Hardness Test, Ultrasonic Testing, Hydrostatic Testing, Pressure testing, and manual inspection of gauge.
The production process can be divided separately for different type of Stainless Steel Fasteners Manufacturers:
Nuts:
Nuts are manufactured from hex bars. The hex bars are subject to CNC Machining that ensures the nuts are compatible with the bolts of the given size.
Bolts:
The bolts are manufactured from round bars either original bright or forged. The bolts are then threaded as per size. The head is either round, hex or of different shape as required in order specification.
Washers:
Washers are manufactured from plates. The size of hold depends on the bolt and nut along with which it has to be used.
Our intelligent procurement module places a lot of emphasis on selection of raw material. As much as possible, we try to procure Japanese and European origin raw material domestically or from the international markets. Secondary preference is given to Indian and Chinese origin raw material from good quality mills.

This heat number is 100% traceable to our records and we maintain very strict watch to ensure the authenticity of our brand isn’t duplicated by other brands.
Stainless Steel Fasteners suppliers are packed in special and branded carton boxes and crate boxes depending on the mode of transport. Fittings are wrapped with special nets to protect the threads.Ends are protected by plastic caps. They are then packed in the carton or wooden boxes.It is important that the damages in transit are avoided and pipe fittings reach customer in the same form as it is manufactured. Thus we place lot of emphasis on packing and packaging of the goods.Stainless steel fasteners carry various export documents such as commercial invoice, packing list, Test Reports, HS Code, Country of Origin attested by chamber of commerce, Fumigation Certificate, Warranty Letter, and Base Material Certificates.Each heat and lot of tube fittings is supplied with a material test certificate as per EN 10204 NACE 3.1 standards indicating the chemical and mechanical properties of the Stainless steel fasteners along with pressure rating. We also confirm the guarantee of the Stainless steel fasteners supplied as per Purchase order specifications and attest the same in the Material Test Certificate. We also welcome any third party inspection from an agency nominated by the customer to comply with NACE 3.2 Certification if required by customer at an extra cost.
Free samples in Stainless steel and carbons steel can be provided upon request to gauge quality and finishing of our fittings against confirmed receipt of purchase order. We can also send photos upon request.
Weather small order or big order, we place a lot of emphasis on intelligent procurement modules. Real time inventory is maintained of all the available sizes in house and in the market; so much time is spend on the manufacturing process and less on sourcing the raw material. Standard sizes are available in ready stock in Stainless Steel and Carbon Steel. All special grades are made to order. We undertake export orders irrespective of small or big quantities. We are the preferred choice of brand for urgent delivery and shut down projects due to our impeccable delivery system module.
