Alloy 20 Fastener, Alloy 20 Nuts, Alloy 20 Bolts Manufacturer, Supplier, Stockist – Screws, Threaded Rod, Anchor – Incoloy 20 Nuts/Bolts, Incoloy 20 Fastener
- We are a leading professional manufacturer and supplier of various types of Alloy 20 fasteners (Sizes M6 to M72) such as bolts, nuts, screws, threaded rods, washers, rivets, anchors, cotter pins, clevis pins, hose clamps, and metal stamping’s. We also produce non-standard inch and metric fasteners according to customer drawings and samples. We supply DIN, EN, ISO, ANSI, ASME, ASTM, BS, JIS, UNI and more metric and inch standard fasteners, non-standard and customized fasteners – DIN (912, 931, 933, 934, 125, etc.); ISO (4014, 4017, 4032, 4035, etc.); ASME (B18.2.1, B18.2.2, B18.2.3, etc.).
- Manufacturing Process of Alloy 20 Nuts, Bolts and Fasteners: – To achieve the high precision requires, our Alloy 20 bolt/screw, nut and washer are produced by the following manufacturing techniques:
- Lathing and CNC lathing – for surface and threads
- Milling and CNC milling – for screw’s head
- Drilling and punching – for washers
- Threads rolling – for threads
- Finished Alloy 20 fasteners will be appropriately annealed to relief residual stress and inspected by Go/no go gauge for every piece.
- For screw and bolts, we can offer full threads, half threads or particularly according to your drawing. Washer and spacers are precision cut from sheet products or stamped by designed molds. Rivets are pins are produced from wire or rods, by further cutting, bending or punching.
- Alloy 20 Bolt is readily fabricated by either hot-working and cold-working, machining, or welding. Although Alloy 20 Fasteners & Alloy 20 Bolts are very difficult to machine as compared to steel, since Alloy 20 work-hardens very quickly. Alloy 20 Fastener Manufacturers have to turn and work with the alloy at slow speeds and low feed rates. In comparison to stainless steel, the Alloy 20 Bolts price is much more expensive, therefore the use of Incoloy 20 has been limited to only these applications where it is impossible to replace them.
- All Alloy 20 and Incoloy 20 distributor in India. Please rest assured to wholesale quality products at stock price from our factory. We specialize in Alloy 20 nuts, bolts and fasteners manufacturing and are made to requested size & tolerance, or to specific drawing.
- We are manufacturing Alloy 20 fasteners by following a stringent quality control program and standards which assure good surface and close dimensional tolerances. We are a global industry leading provider of carbon steel, alloy steel and stainless steel fastener solutions and have obtained ASME Quality and ISO 9001:2015 Certifications.
- All our fastener products are supplied with 3.1 specific test certificates, according to EN 10204. Certification according to 3.2 can be agreed at the time of ordering. Metallica makes it easy for you to source top quality steel fasteners at the lowest prices.

Prices for Alloy 20 Nuts, Bolts, Fasteners
Prices for Alloy 20 Nuts, Bolts, Fasteners are directly co related to prices of the raw materials such as iron ore, metal scrap, chromium, nickel and various other alloying elements. The production cost of heat resistant stainless steel and nickel alloy plates is high as they contain high amount of nickel and chromium. Meanwhile, mild steel material is among the lowest cost steel available, followed by carbon steel, 400 series stainless steels, aluminium, alloy steel, and 300 series stainless steel. Special alloys such as titanium, Inconel, Monel and Hastelloy cost very high as the nickel, chromium and moly content is very high.
