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.

Swivel-Tip Set-Screw Grippers
Grip angled and uneven surfaces with precision and ease. These grippers thread into either side of your fixture or plate. You can even position them so their serrations are flush with the surface. Adjust their height with a hex key. For a secure hold, clamp your workpiece against them.
Ultra-fine serrations are the most closely spaced for the lightest penetration of the workpiece.
Extra-fine serrations are a little farther apart than ultra-fine serrations, so they penetrate the workpiece slightly more for a firmer hold.
