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.

Hardened steel buttons are stronger and resist wear better than steel buttons. They are precision ground, which helps them maintain their shape and size, even with repeated use. This makes them a good choice for use in modular fixtures where repeatability and exact positioning are important.

Buttons with a domed head support rounded or irregularly shaped workpieces with minimal contact.
