Taper Pins - Imperial

Taper pins are small, solid steel tubes that resemble dowel pins but that are tapered – one end has a greater diameter than the other end.

They are manufactured to a very high tolerance to ensure that they are a precise fit. They are generally used for locking components in place in mechanical engineering applications, often in gearboxes and on camshafts.

Taper pins are tapped into position with a hammer or drift.

Imperial is a generic term used to describe threads that were in common use before the metric standard was adopted. Types of imperial threads include UNC, UNF, BSW, BSF, BA etc. Many of these thread types are still commonly used today.
