Taper Pins

Often used for positioning components and securing assemblies, these pins taper at a uniform rate to fit snugly in tapered holes. They have slightly rounded edges to aid insertion. To install, create a tapered hole using a taper-pin drill bit that matches the pin number for inch sizes or the small end diameter for metric. To remove, hit the small end of the pin with a punch to drive it out.

Breaking strength is measured as single shear, which is the force required to break the pin into two pieces.

Steel pins have good strength.

Metric pins meet DIN 1 specifications.
