Bolt is a cylindrical threaded fastener with a nut. A type of fastener consists of a head and a screw (a cylinder with an external thread), which needs to be matched with a nut to fasten.
Pin is used to position and fasten components. There are two types, cylindrical and conical. The installation of pins generally adopts two methods, press-in method or knock-in with soft metal. Pins are usually conical, pointed or pointed wood or metal pegs, to nail or fasten or to fill holes.
Sibai doesn't focus on production bolt and pins. But if customer requires, we can help purchase from Chinese supplier. Besides this, Sibai can produce the customized bolts or pins according to customers specific designed drawings.
There are several processings:
Head forming processing: The inner end side of the high-strength bolt and the center line of the rod have verticality requirements, generally between 0.04-0.10mm. In order to ensure the tensile strength of the high-strength bolt, the inner end face is required to be chamfered R, value generally R1 ± 0.5.
Rod processing: external surface processing by turning and grinding, the semi-finishing accuracy can reach IT10-IT9, and the surface roughness value can be Ra 6.3 - 3.2um. Cylindrical grinding is the main method of cylindrical finishing, generally after heat treatment.
Thread processing: There are several ways to produce thread, turning, milling, grinding, rolling, etc. For high-strength bolts, we choose rolling threads. Rolling is a chip-free machining process. The thread is formed by cold forming. Rolling has high capacity.
Heat treatment: treatment of high-strength bolts (quenching and high temperature tempering).
Surface treatment: according to customers requirements, there are several common surface treatment for bolts and pins, dacromet, zinc plating, surface phosphating. Galvanization and phosphating are mostly used in our past production experience.
Sibai also exports a large number of fasteners, especially high-strength custom bolts. If you have production needs for custom bolts and pins, please contact me for a quote. thanks.
