What is a split pin, and how is it used?

A split pin, also known as a cotter pin, is a fastener inserted through a shaft hole and bent at the ends to secure components in place.

What are the benefits of using stainless steel split pins?

Stainless steel split pins, particularly SUS316 and SUS316L, provide excellent corrosion resistance.

Can Misumi split pins be reused?

It’s generally not recommended to reuse split pins since bending and unbending them weakens the material, reducing reliability.

Do brass split pins offer any advantages over steel or stainless steel?

Brass split pins are non-magnetic, corrosion-resistant, and softer, making them ideal for electrical and decorative applications.
