parallellkäftklämma

A parallellkäftklämma, also known as a parallel jaw clamp or machinist's clamp, is a type of clamp used in woodworking and metalworking. Its defining feature is a pair of jaws that remain parallel to each other throughout the clamping operation. This parallel action ensures that the clamping force is distributed evenly across the workpiece, preventing marring or uneven pressure.

The jaws of a parallellkäftklämma are typically made of metal, often steel, and are sometimes faced with softer materials like rubber or wood to protect the surface of the workpiece. The clamping force is usually applied by a screw mechanism, which can be operated by a handwheel or a T-handle. This allows for precise adjustment of the clamping pressure.

Parallellkäftklämmor are valued for their stability and the consistent pressure they provide. They are commonly used for holding workpieces during drilling, sawing, filing, or gluing operations where precise alignment and secure holding are critical. Unlike C-clamps, which can apply pressure at an angle if not perfectly aligned, parallellkäftklämmor maintain a perpendicular grip. They are available in a range of sizes to accommodate different workpiece dimensions.
