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.

Swivel-Tip Gripper Screws
The serrated tip swivels to grip uneven and angled surfaces and the threaded stud lets you make quick height adjustments.
Ultra-fine serrations are the most closely spaced for the lightest penetration of the workpiece.
Extra-fine serrations are closer together for less penetration and a lighter hold on the workpiece.
Fine serrations penetrate the workpiece for aggressive holding.
