Manufacturing Fasteners – Nut, Bolts, Screws & Washers

Fasteners, nuts, bolts and screws are generally manufactured by two processes namely cold forging and hot forging.

  • The cold forging process is generally used for manufacturing small size fasteners while hot forging process is used for large size bolts and nuts. The cold forging process starts with large steel wire rods, which are uncoiled and cut to length. This is followed by pressure forging, cold extrusion and reducing, or a combination of these procedures, followed by heat treating to improve strength and surface treating to improve durability.
  • Many other fasteners are also produced by the cold forming or forging process especially for producing large quantities, as it reduces the cost of production. The choice of the suitable forming machine depends on the size of the fastener and on the degree of forming. The greater the degree of forming, the more forming stages are required.
  • Screws are usually produced by cold forming process where in we usually receive the wire coiled on rolls.
  • Heat treatment process is used after the fastener production to increase the strength or control the mechanical properties of fasteners.
  • Nuts are usually produced with the cold or hot forming procedure as well. The choice of one or the other procedure depends on the one hand on the size and on the other on the required quantities.
  • The hot forging or forming production method is used mainly to manufacture large diameters starting with approx. M27, and longer pieces starting from approx. 300 mm. In addition, parts are possible that cannot be produced using cold forming because of the very small volumes, or because of a very high degree of forming.
  • Washers are produced by punching or forming process. The manufacturing process starts with making of punching die as per the required internal and external diameter of washer.

Prices for U Bolts

Prices for U bolt products 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 U Bolts 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.
