Machine Table Clamps

Self-Supporting Setup Clamps

Self-Supporting Setup Clamps

Eliminating the need for step blocks or other rear support, the pivoting rocker clamps workpieces of various thicknesses.

Setup Clamps

Use with T-slot nuts or bolts and a support to secure a workpiece, vise, or fixture to a machine table.

Step Setup Clamps

Step Setup Clamps

The stepped end provides support and quick height adjustment when paired with a step block.

Setup Clamps with Threaded Hole

Setup Clamps with Threaded Hole

Instead of a step block, support these clamps using a screw, leveling mount, or any other threaded object.

Setup Clamp and T-Slot Fastener Kits

Setup Clamp and T-Slot Fastener Kits

Get everything needed for basic workholding on a machine table.

Economy Setup Clamp and T-Slot Fastener Kits

Economy Setup Clamp and T-Slot Fastener Kits

Good for occasional machining, economy kits contain lower-strength components than standard kits.

Low-Profile Setup Clamps

The offset shape provides more clearance above the nut than standard clamps. Also known as gooseneck clamps.

Low-Profile Setup Clamps with Threaded Hole

Designed to provide more clearance above the nut than standard clamps, these have an offset shape. Also known as gooseneck clamps.

Dual-Clamping Low-Profile Setup Clamps

Position these clamps between two workpieces, vises, or fixtures and secure both to your machine table using T-slot nuts or bolts.

Step Blocks

Step Blocks

Use these blocks to support setup clamps. Fit the nonslip steps together for quick height adjustments.

Nonmarring Setup Clamps

A plastic pad on the gripping surface of these clamps prevents workpiece marring, making them useful for holding polished surfaces and reducing the need for secondary finishing steps.

Setup Clamps for Angled Workpieces

Setup Clamps for Angled Workpieces

Unlike other setup clamps that grip the horizontal surface of a workpiece, these clamps have a pivoting ball in the tip to get a firm hold on angled parts.

Setup Clamp Supports

Setup Clamp Supports

Keep setup clamps from falling out of position when they are unclamped—the spring holds them up for quick workpiece insertion and removal. Also known as spring lifters.

Fingertip Setup Clamps

Fingertip Setup Clamps

Making minimal contact with the workpiece while holding securely, these clamps are good for small parts and can clamp into holes and notches.

T-Slot Side Clamps

T-Slot Side Clamps

The built-in T-slot nut on these side clamps lets you clamp a part to a machine table quickly. Their small footprint leaves more free space on your table than standard side clamps.

Side Clamps

Also known as toe clamps, these grip the side of a workpiece to leave the top free for machining.

Hold-Down Machine Table Clamps

Hold-Down Machine Table Clamps

An alternative to setup clamps, these heavy duty clamps have high holding power to secure workpieces during machining.

Vise Mounting Clamps

Smaller than standard setup clamps, these clamps leave more usable space on a machine table when mounting a vise.

Machine Table Clamps for Round Workpieces

Machine Table Clamps for Round Workpieces

Use these clamps to hold large round parts for machining. Each clamp comes with five lengths of chain that combine to accommodate different size workpieces.

T-Slot Blocks

T-Slot Blocks

T-Slot Blocks

Mount these versatile blocks to any flat surface for machine table-style T-slot clamping. They can also be used on a machine table to clamp parts at specific angles or add more total clamping points.
