Low-Profile Setup Clamps with Threaded Hole
Designed to provide more clearance above the nut than standard clamps, these have an offset shape. Instead of a step block, support them using a screw, leveling mount, or any other threaded object. Pair with a T-slot nut or bolt to secure a workpiece, vise, or fixture to a machine table. Also known as gooseneck clamps.

Low-Profile Setup Clamps
The offset shape provides more clearance above the nut than standard clamps. Use with T-slot nuts or bolts and a support to secure a workpiece, vise, or fixture to a machine table. Clamps can be supported with step blocks or any flat object. 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. Their low-profile shape provides more clearance for cutting tools above them than standard clamps.

Spring Clamps with Flexible Arm
Attached to an arm you can flex into position, these clamps hold objects such as a flashlight, tool, or instructions. Squeeze the handles to open the clamp; release and the spring holds it tightly in place.
Magnetic-mount clamp attaches to steel surfaces.

Bend-and-Stay Positioning Arms
Stronger and with greater load capacities than gooseneck-style positioning arms, these arms keep their shape even when moving or when exposed to vibration. They’re often used in robotics and conveyor applications when frequent repositioning isn’t required.
All accessories include the necessary hardware for attaching them to arms.
Clamp-on bases have two arm attachment locations. Place arms straight or at a right angle from the clamping screw. Clamp-on bases with a rubber V-block can be mounted to rounded surfaces such as pipe and railings.
Spring clamps with three attaching end mounting holes can be mounted parallel or perpendicular to your positioning arm. Spring clamps with a 4 1/2" reach clamp further into a workpiece than other spring clamps.
Three-finger clamps have bent fingers to hold workpieces that are hard to grip, such as beakers, flashlights, and webcams. A rotating position lock lets you rotate these clamps on your positioning arm. Secure clamps in place with the included locknut.
