Customized Bolts And Pins

Sibai doesn’t focusing on production bolt and pins. But if customer requires,
we can help purchase from Chinese supplier. Besides this, Sibai can produce the
custom stainless steel bolts or pins according to customers specific designed
drawings.

Sibai custom bolts and fasteners Features
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 custom carriage bolts and pins. But if
customer requires, we can help purchase from Chinese supplier. Besides this,
Sibai can produce the custom eye 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
