Grippers
Maintain a secure hold on uneven or irregularly shaped parts by clamping against these serrated grippers.
Grippers with a threaded through-hole/set screw notch mount from the bottom with a socket head cap screw or from the side using a set screw.
Grippers with an unthreaded through-hole mount from the top with a socket head cap screw.
Grippers with a threaded through-hole mount from the bottom with a socket head cap screw.
Fine serrations penetrate the workpiece for aggressive holding.
Extra-fine serrations are closer together for less penetration and a lighter hold on the workpiece.

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.
