PIH-60020 - Piher Maxi F-20 Heavy Duty Piston Clamp 20cm

Heavy-Duty Welding Clamp with Spatter Protection

For professional welders and fabricators, the Piher Maxi F-20 Clamp is an essential tool designed to withstand the harsh conditions of the welding shop. Standard clamps often fail when welding spatter adheres to exposed threads, seizing the mechanism and rendering the tool useless. The Piher Maxi F solves this problem with its innovative Piston System, which completely conceals the thread inside the cylinder. This protection ensures that no matter how much spatter flies, your clamp will continue to operate smoothly day after day.

Power is critical in metal fabrication, and the Maxi F-20 delivers. With a clamping force of 1980 lbs (900 kg), it can pull together heavy steel plates and hold them securely for tacking and welding. The 12cm (4.72") throat depth provides ample reach for most fabrication tasks, while the 20cm (7.87") opening capacity handles a wide range of material thicknesses. The bar is made from high-strength steel (35mm x 8mm) to prevent flexing, ensuring your workpiece stays square and true.

Ergonomics and safety are also key features. The handle is designed to transmit maximum torque comfortably, and the moving jaw includes a brake to prevent slipping. The cast iron jaws are durable enough to handle heat and rough handling. If you are looking for a clamp that lasts longer than standard F-clamps in a welding environment, the Piher Maxi F-20 is the superior choice. It combines the speed of a quick-action clamp with the raw power of a heavy-duty screw clamp.
