Piher Maxipress F-Style Piston Clamps

Piher's Maxipress F-Style Piston Clamps feature dual-threaded screw mechanisms that multiply both clamping speed and force. The threads are split into upper and lower sections, both of which are completely encased in a metal cylinder: the ''piston.'' The two screws are threaded opposite one another, and work together to close the clamp 50% faster than ordinary clamps. They also generate 40% more force—up to an incredible 2,250 pounds. In addition, the clamp foot advances like a piston—without spinning—so any twisting forces that could cause misalignment or marring are minimized.


Features:

  • Clamp foot advances without rotating, minimizing any twisting torque that could cause misalignment or marring
  • Totally enclosed threads keep out dust, glue and protect the threads from impact
  • Grease port allows you to lubricate the screw threads when necessary
  • Handle swivels 90° in either direction and locks into place for additional leverage. Use it in the in-line position where space is restricted
  • Grooved jaw heads let you clamp tubular items and other profiles
  • Spring-assisted brake prevents the movable jaw from sliding open, even without clamping force
  • Heavy-duty cold rolled steel bar provides incredible beam strength and maximum durability
  • Due to the robust thickness of the bar on these clamps, they will not fit into our F-Style Clamp Rack. For convenient storage, use our Parallel Clamp Rack (#38498, sold separately) instead.

Heavy duty clamp!
The thickest / strongest bar on a clamp I've seen. Tilting handle gives extra torque: must pad against marks in woodworking project. Only plastic is covering on handle: Yes, use with welding applications would work.

amazing clamps
These clamps are in a whole different league than Jorgensen HD or Bessey Tradesman or any other f-style bar clamp I've seen. I just can't get any flex at all out of the 8 x 35 mm bar. The sealed threads, 2:1 step-up, and solid face on the adjustable side are beautiful. Heirloom quality if I've ever seen it. Of course clamps as beefy as these are heavier...about 5.6 lbs for the 16" clamps. To be complete, these are the Piher MAXI-F clamps. The Piher website also lists the MAXI-R clamp...beefier, stronger, 8" throat depth, and 8.4 lbs apiece for the 40 cm clamps. I have yet to find a source (in this country) for the MAXI-R clamps, and am not sure I'd buy them anyway.

Great Clamps
Super heavy duty. No deflection and the handle set at right angle allows for maximum pressure without torquing your wrist!

These clamps rock!
I was having trouble deciding between steel bar clamps and aluminum bar clamps...these clamps were a great choice. They blow the others away. I like the innovative design . Clamping pressure is great and well-maintained throughout use. They have a little heft but not overly heavy or bulky. Clamp pads will solve any imprint in softwood problems from the X-face. Well-satisfied and will likely buy more of these!

Piher maxi clamps
I love the Piher clamps, we have used the blue Pihers in our shop for years, they are preferred above all other "F" style clamps. I just received 2 of the new maxi clamps and I was surprised by one detail: the face of the head of the clamp has an "x" pattern not a smooth surface. Probably not ideal for most wood surfaces without a caul. these are very heavy duty durable clamps both the blue guys and the red. the pistons make a difference and the clamp threads stay cleaner than those on the Jorgenson version, which we have plenty.

My new favorite clamp
These clamps are heavy duty. The piston design might seem minor but when doing critical fitting, then clamping the piston design makes a real difference- there is no twisting action applied to the workpiece by tightenting the clamp. This relatively minor thing actually makes abig difference in assembly and gluing operations.

I needed this size F-clamp & was willing to pay for the advanced features. I'll probably buy more if they work as expected.
