About Pins , it is for fastening,like object or material together.
Like Spring Cotter Pin, Split Pins, Parallel Pins. and so on. we can produce all standards, but our Non-standard Pins can be produce according to drawings and samples.
A pin is a device used for fastening objects or material together. Pins often have two components: a long body and sharp tip made of steel, or occasionally copper or brass, and a larger head often made of plastic. The sharpened body penetrates the material, while the larger head provides a driving surface.

In engineering and machine design, a pin is a machine element that secures the position of two or more parts of a machine relative to each other. A large variety of types has been known for a long time; the most commonly used are solid cylindrical pins, solid tapered pins, groove pins, slotted Spring Pins and spirally coiled spring pins.
