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.
