Clamping and Workholding

Grippers

Maintain a secure hold on uneven or irregularly shaped parts by clamping against these serrated grippers.

Set-Screw Grippers

Screw in from the top to adjust height or mount from the bottom with a hex key to set the gripping surface flush with the work surface.

Hex-Head Gripper Screws

Make quick height adjustments by turning the threaded stud.

Swivel-Tip Gripper Screws

Screw these grippers into place and make quick height adjustments.

Side Grippers

Clamp against these grippers for a secure hold on workpiece edges.

Angled Grippers

The face of these grippers is angled 15°. They can be used in the jaws of lathe chucks.

Swiveling Gripper Tips for Screws and Threaded Studs

Attach to the end of a screw or threaded stud—the serrated face swivels to grip uneven and angled surfaces. Also known as toggle and swivel-foot pads.

Lathe Chucks

Hardened Lathe Chuck Jaws

Made from hardened steel, these jaws have a long service life even when performing heavy machining such as roughing cuts.

Machinable Lathe Chuck Jaws

Machine these jaws to fit the curves and edges of your unique workpiece for a tighter hold and more stability than standard hardened jaws.

5C Collet to Lathe Chuck Adapters

No need to break down a collet set up when a workpiece doesn't fit a 5C collet. Install one of these lathe chuck adapters in your 5C collet chuck or holder and its three jaws will securely grasp the workpiece.

Lathe Chuck Jaw Nuts

Secure jaws to a CNC lathe chuck with industry standard 1.5 mm × 60° serrations or wider 3 mm × 60° serrations.

Boring Rings for Machinable Lathe Chuck Jaws

Hold machinable lathe chuck jaws in place during machining to make accurate cuts, ensuring the jaws will securely grip your workpiece.

Three-Jaw Lathe Chucks

Also known as scroll chucks, these are self centering—all three jaws move in unison, centering the workpiece as they close.
