NO. 6312 VS Crocodile Clamps Steel, with Adjustable Holders, with Clamping Stud

Crocodile Clamps NO. 6312 VS: Steel, with Adjustable Holders, with Clamping Stud

Product description

Crocodile clamps NO. 6312 VS are infinitely adjustable, easily expanded for every clamping height. They are used for a variety of clamping applications including those using T-grooves and threaded holes.

Compression piece and adjustable holders are connected permanently to the clamp body, so the crocodile clamp can be used quickly.

The clamp body is equipped with two varied clamping surfaces and can be easily turned to use one side or the other. Due to the fully assembled construction, this makes for easy set-up and handling on equipment.

Crocodile clamps are especially suitable for use on injection molding machines and various presses.

*Specified clamping forces in optimal clamping position (smallest distance from the clamping screw to the clamping point). Clamping forces can vary depending on clamping, strength class of the clamping screw, and the condition of the thread (lubrication).
