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 Carbon 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.

Our quality program is a 3 layered independent department check for various factors including Dimensional Check, Visual Inspection, and Finishing, Burr level, Leakage Test, Pressure Rating test, Chemical inspection and Mechanical properties verification. We are running at full capacities and sometimes outsource our job due to increased work load.

Our fasteners carry our brand identity with special brand marked on the fittings. Our brand i-Fit is branded on all Carbon Steel Fasteners exported from our company. i-Fit is a registered brand owned by Instinox which stand for intelligent fitting connections we provide for international markets. Use of intelligent technology modules is used for providing a seamless buying experience for high quality i-Fit Carbon Steel Fasteners.

Carbon Steel Fasteners Suppliers are marked with standard format of i-FIT-Size-Material-Heat Number. 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.

Carbon 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.

Carbon 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 pipe fittings along with pressure rating. We also confirm the guarantee of the fittings 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.
