The Manufacturing Process of Bolts, Screws and Studs - Part 1
Bolts, screws and studs are important fasteners used in a variety of industrial applications. The successful use of these fasteners depends largely on their manufacturing process. In this article, we will discuss various aspects of manufacturing these bolts, screws and fasteners.
Basic Fastener Manufacturing Process
Most fasteners are manufactured using materials such as stainless steel, carbon steel, brass, aluminum and plastic. The manufacturing process of fasteners is unique depending on their respective functions. The following points explain each step in detail:
Select Raw Material: The raw material is determined based on the application and fastener requirements. Materials need to be checked to ensure they meet blueprint specifications. Materials need to be received, inspected, documented and I.Ded for proper manufacturing process.
Creating Fasteners: Some of the methods used to create fasteners are as follows:
CNC Machining: Raw materials in bar form are programmed into computerized machining centers to manufacture close tolerance small and medium-sized screws, bolts, fasteners and custom machine parts.
Single-Axis Screw Machining: A faster production method for manufacturing medium and large fasteners, inserts, flanges, pins and machined parts at a lower cost.
Multi-Spindle Screw Machining: A very economical manufacturing process that provides high-volume precision parts. Bars are fed into a machine with several stations. Each workstation performs a different operation, resulting in custom-designed fasteners and machined parts. Parts are unloaded from the machine according to blueprint specifications.
These are the first two steps in the bolt, screw and fastener manufacturing process. The next article will discuss optional steps, along with testing and inspection.
