In all-steel clamps, the fixed bracket with moulded pressure plate is forged from a single piece, tempered and galvanized. This gives the clamp its special resilient and elastic properties. Compared to rigidly clamping malleable cast iron clamps, the spindle can be turned more often to achieve the required clamping force. All-steel screw clamps are also less sensitive to vibrations. They are therefore indispensable aids for a wide range of applications in wood and metal processing.
