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.

Inch

Inch pins meet ASME B18.8.2 specifications for material and dimensions.

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

18-8 Stainless Steel—18-8 stainless steel pins offer a balance of strength and corrosion resistance. They may be mildly magnetic.

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

Tapped Taper Pins

These internally threaded pins sit flush in an assembly. For easy removal from a blind hole, thread a screw into the pin and pull out. Often used for positioning components and securing assemblies, they taper at a uniform rate to fit in tapered holes. Use a tapered drill bit that matches the pin number for a snug fit. They have slightly rounded edges to aid insertion.

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

ASME B18.8.2—Pins meet ASME B18.8.2 specifications for material and dimensions.

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.

Inch

Length for inch pins measures the unthreaded length of the pin.

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

ASME B18.8.2—Pins that meet ASME B18.8.2 specifications conform to ASME standards for material and dimensions.

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