Clamp thin materials and in tight spaces. Squeeze the handles to open the clamp; release and the spring holds it tightly in place. 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.

Style A clamps have alligator-grip jaws to hold material securely.

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

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

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.

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.

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 clamps have a 700° F maximum temperature for use in electroplating applications.

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

Clamps with a cushion grip are comfortable to hold.

Clamps with a plain grip have an all-metal construction that makes them good for holding parts while soldering. Style A and B clamps have a textured handle that helps you get a better grip.
