Send Your RFQHot and Cold Forged Fasteners
We make fasteners by hot forging for large diameters and high-strength grades, and by cold forging for accurate, high-volume parts. Threads are rolled for extra fatigue strength or cut for special sizes and short runs, and every batch is checked by proof load, hardness and tensile testing before dispatch.
Our Fastener Products
Bolts
We make hex bolts, screws and custom bolts in all general sizes and grades to IS, DIN, ISO and ASTM standards, or to your drawing. Bolts are hot or cold forged, with threads rolled or cut, for machinery, structures, equipment and OEM assemblies.
Nuts
We make hex nuts and custom nuts to match our bolts, in all general sizes and grades to standard or to drawing, so bolt and nut come from one supplier with matching thread and strength class.
Washers
We make plain washers and spring lock washers to standard sizes. Washers spread the load under the nut or bolt head, and spring lock washers keep the joint tight under vibration.
Cotter Pins & Lock Wire
We make cotter pins and lock wire to standard sizes for locking castle nuts, clevis pins and bolted joints that must not work loose. See our cotter pins range for sizes and packaging. Read our cotter pin guide →
Steel Nails
We make steel nails and nail coils in standard sizes or to your requirement, for construction, packaging and industrial use.
Ring Gaskets
We make ring-type joint (RTJ) gaskets to API 6A for wellhead equipment, pipelines and high-pressure flanged joints, where a metal-to-metal seal must hold under high pressure and temperature. See our API 6A ring gaskets.
Anchor Bolts
We make anchor bolts to IS, DIN and ASTM standards or to drawing, for fixing structures, machinery and equipment to concrete foundations.
Threaded Rods
We make threaded rods in carbon and stainless steel to standard sizes or to drawing, for structural fixing, hangers and long bolted joints, used with our nuts and washers.
Rivets
We make steel rivets to standard or drawing for permanent joints in sheet metal and structural assemblies.

Sharma Technocast is ISO 9001:2015 certified (accredited and verifiable on IAF CertSearch). Every batch is tested before dispatch, and we welcome third-party inspection by your nominated agency.
| Certification | ISO 9001:2015 Quality Management System |
|---|---|
| Mechanical testing | Proof load, hardness and tensile testing for every batch |
| Dimensional checks | Thread fit and dimensions checked against the standard or drawing |
| Standards | IS, DIN, ISO and ASTM, or the client's drawing; API 6A for ring gaskets |
| Coatings | As per the standard or the client's requirement |
| Documents supplied | Material test certificates and batch test reports (proof load, hardness, tensile) |
Frequently Asked Questions
A fastener is a part that joins two or more components mechanically, such as a bolt, nut, screw, washer, cotter pin or rivet. Threaded fasteners like bolts and screws can be removed and refitted; pins and rivets lock or join permanently.
We make bolts, nuts, screws, washers, spring lock washers, cotter pins, lock wire, threaded rods, anchor bolts, rivets and nails, plus API 6A ring gaskets, in standard sizes or to the client's drawing.
A bolt passes through the parts and is tightened with a nut, while a screw threads into one of the parts or into a tapped hole. Bolts are usually used for heavier structural and machinery joints.
A bolt passes through the parts and is tightened with a nut, while a screw threads into one of the parts or into a tapped hole. Bolts are usually used for heavier structural and machinery joints.
We make fasteners to IS, DIN, ISO and ASTM standards, or to the client's drawing and specification. Ring gaskets are made to API 6A.
We make fasteners in all general grades of carbon steel, alloy steel and stainless steel, with coatings as per the standard or the client's requirement, chosen for strength, temperature and corrosion conditions.
Fasteners are hot forged or cold forged to shape, and threads are rolled or cut to suit the size, grade and quantity. Rolled threads give extra fatigue strength; cut threads suit special sizes and short runs.
Every batch is checked by proof load, hardness and tensile testing, along with thread and dimensional checks, and we supply material test certificates and batch test reports with the order.
Yes. We make custom fasteners to your drawing, including special sizes, lengths, head shapes and grades, as well as standard fasteners.
Typical manufacturing lead time is 30 to 45 days, depending on quantity, size and grade.
