Pin standards

Pin, also known as pin, is a commonly used fastener, usually made of cylindrical wood, metal or other materials, used to fasten several separate objects together or as a support for one object to be suspended on another object. The standards for pins include different types and specifications to meet various application requirements. For example, dowel pins follow the GB/T119.1-2000 and GB/T119.2-2000 standards, internal threaded cylindrical pins follow the GB/T120.1-2000 and GB/T120.2-2000 standards, and tapered pins follow the GB/T117-2000 standard. These standards ensure the consistency and interchangeability of pins, thereby improving the performance and safety of mechanical equipment.

In addition, pins are classified according to materials, including stainless steel pins, 304 stainless steel pins, 201 stainless steel pins, 316 stainless steel pins, etc., as well as frequently used materials such as 35 or 45 steel. The choice of these materials depends on the specific application environment and performance requirements.
