Threaded Taper Pins
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.
Breaking strength is measured as single shear, which is the force required to break the pin into two pieces.
Steel pins have good strength. Pins that meet ASME B18.8.2 specifications conform to ASME standards for material and dimensions.
18-8 stainless steel pins offer a balance of strength and corrosion resistance. They may be mildly magnetic.
Length for inch pins measures the unthreaded length of the pin.

Threaded Locating Pins
Screw the shank into a threaded hole for quick installation and removal. Mate these pins with holes in workpieces for precise alignment.
Diamond-head pins make less contact with the inside of a hole than round-head pins to reduce sticking and jamming.

Threaded Locating and Support Buttons
Use these buttons to support and position workpieces and fixtures from the bottom or side. Their hex shape lets you screw them into a threaded hole with a wrench or socket. Threading makes these buttons easier to replace than press-fit, so they are a good choice for high-wear applications. They’re also known as rest buttons.
