The AN 77 is a cotter pin, often called a pin because of its unusual shape. It resembles a check - a metal ring with a thin or thick core. Due to this shape, the products are widely used for transverse fastening of pipes, axles, and shafts. But this hardware is not designed for high loads.
Materials used to manufacture AN 77 cotter pin
The AN 77 cotter pin is made of steel and additionally coated with yellow zinc.
Areas of application of the cotter pin
The quick-release cotter pin with ring AN 77 is used for fixing parts on axles. The AN 77 cotter pin is especially widely used in agricultural engineering. When using this fastener, installation and dismantling of axle assemblies is much faster.
The scope of application also directly depends on the material of manufacture and coating of the product: Yellow zinc protects against corrosion if the fastener is to be used in aggressive environments.
