Threaded Taper Pins

Tighten the

nut to draw

the pin out of

the hole.

Threads on these pins stick out for easy removal from blind holes. Tighten the hex nut to draw the pin out. Often used for positioning components and securing assemblies, they taper at a uniform rate to fit in tapered holes. For a snug fit, use a tapered drill bit that matches the pin number for inch sizes or the small end diameter for metric sizes. They have slightly rounded edges to aid insertion.

Metric

Length for metric pins measures the overall length, including the thread.

12L14 Carbon Steel—12L14 Carbon steel pins have good strength.

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