Miniature Spring Clamps

Style E	Style F

Style G	Style H

Style J	Style K

Style L	Style M

Style N

Clamp thin materials and in tight spaces. Squeeze the handles to open the clamp; release and the spring holds it tightly in place. They have an all-metal construction that makes them good for holding parts while soldering.

Clamps with a hole on the end can be secured to your workholder’s arm, so your hands are free for soldering, gluing, and assembling.

18-8 Stainless Steel Body—18-8 stainless steel clamps resist high temperatures, so you can use them as a heat sink. These clamps are good for soldering because solder won’t stick to them.

17-7 PH Stainless Steel Body—17-7 PH stainless steel clamps resist high temperatures, so you can use them as a heat sink. These clamps are good for soldering because solder won’t stick to them. They have a 700° F maximum temperature for use in electroplating applications.

Aluminum Body—Aluminum clamps are lightweight. They also conduct heat and electricity, so you can use them as a heat sink.

Steel Body—Steel clamps are medium weight and good for holding light materials. Since steel isn’t a good heat conductor, these clamps won’t work well as a heat sink.

Style A—Style A clamps have alligator-grip jaws to hold material securely. They have a textured handle that helps you get a better grip.

Style B—Style B clamps have a textured handle that helps you get a better grip.

Style D—Style D clamps have a plate built into their jaws that lets them apply pressure evenly, without denting or marring what they hold. Use these clamps with ceramics, plastics, and other sensitive materials.

Style E—Style E clamps have a support beam that keeps them upright and balanced. They can hold material for a long time without adding extra pressure.

Styles F, G, H, J, and L—Style F, G, H, J, and L clamps have a long bottom jaw for supporting large material or thin sheets and bars.

Style M—Style M clamps have jaws with three sections: a point for precise contact, a flat area for general gripping, and a curved portion for holding round material.

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.

Spring Clamps

4 1/2" Reach Length—Spring clamps with a 4 _1/2" reach clamp further into a workpiece than other spring clamps.

3 Attaching End Mounting Holes—Spring clamps with three attaching end mounting holes can be mounted parallel or perpendicular to your positioning arm.

Grounding Clamps for Welding

Designed specifically for use with welding circuits.

Spring Clamp


Standard	Flat Jaw

Spring clamps have an extended jaw that eases clamping. Both jaws carry current.

Flat Jaw—Flat-jaw clamps grip flat surfaces especially well. They have a larger contact area with the workpiece than standard spring clamps, so electricity flows more easily, but their jaw openings aren’t as large.

Copper Connection—Clamps that are copper prevent weld spatter from sticking.

Cable Support—Cable supports prevent cable strand breakage.
