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.

Screw-Mount Locating and Support Buttons
Also known as rest buttons, these buttons support workpieces and fixtures from the bottom or side. Mount them onto a screw or stud extending from your jig or table.
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.
Hex buttons are easy to turn with a wrench. They have a threaded hole, so you can mount them to a threaded bolt or stud. Those with a domed head support round or irregularly shaped workpieces with minimal contact.

Hex-Head Gripper Screws
Make quick height adjustments by turning the threaded stud. Screw these grippers into place from above and clamp against them. The serrations penetrate the workpiece surface to hold uneven or irregularly shaped parts.
Extra-fine serrations are closer together than fine serrations for less penetration and a lighter hold on the workpiece. Fine serrations penetrate the workpiece for aggressive holding.
Fine threads are closely spaced for more precise adjustments than coarse threads. They also resist loosening from vibration better than coarse threads.
