61060 - Piher Maxipress R Heavy Duty Piston F-Clamp 24-Inch Opening

The Ultimate F-Clamp for Welding and Fabrication

For professional welders and fabricators, the Piher Maxipress R Style Clamp (24" x 6") is more than just a holding tool; it is a solution to the common frustrations associated with standard clamping in harsh environments. Welding shops are notoriously tough on tools, with spatter, grinding dust, and extreme heat constantly threatening the longevity of equipment. The Maxipress R addresses these challenges directly with its fully enclosed screw design. Unlike conventional clamps where the threaded rod is exposed to the elements, this clamp hides the thread inside a sealed piston housing. This means welding spatter cannot adhere to the threads, preventing the common issue of clamps seizing up or becoming impossible to loosen after a job.

Precision fit-up is critical in welding, and the Maxipress R excels here thanks to its piston-action tightening. When you tighten a standard C-clamp or F-clamp, the rotating pad often "walks" the workpiece, shifting your carefully aligned joint just as you apply pressure. The Piher piston system advances the jaw straight forward without rotation, ensuring your metal plates, tubes, or profiles stay exactly where you positioned them. With a massive 1,000 kg (2,200 lbs) of clamping pressure available, you can easily force stubborn steel members into alignment, close gaps for tacking, and hold heavy assemblies rigid during the welding process.

The physical construction of the clamp is designed for the fabrication floor. The jaws are made from nodular cast iron, which offers superior resistance to thermal shock and mechanical abuse compared to standard cast iron. The fixed jaw features a V-groove, making it easy to grip round stock, pipes, and tubing securely—a frequent requirement in frame building and roll cage fabrication. The articulated handle is another welder-friendly feature; it allows you to crank down hard for maximum pressure and then fold the handle out of the way, keeping the work area clear for your torch and welding gun access.

Maintenance is often overlooked in busy shops, but Piher makes it simple with an integrated grease nipple. A quick shot of grease keeps the internal piston moving smoothly, ensuring the clamp is always ready for the next heavy-duty task. For welders who demand tools that work as hard as they do, the Piher Maxipress R provides the holding power, protection, and precision necessary for professional-grade fabrication.
