Workholding Devises

Set-ups will be faster and easier because they eliminate the need for U-clamps and straps, different-length studs and blocking, and complicated clamping arrangements. There are no separate parts to be replaced.
“Dubl-Action” Jaw Clamps and “Dubl-Action” Jaw Fixture Clamps
With only one adjusting screw providing all the force necessary to position and hold workpiece, controlled gripping is fast and simple. During production runs, some clamps can be left in position while others are loosened for loading and unloading.

Gripping will be vastly improved through our original “Double Action” design. Each turn of the adjusting screw brings the jaw in and down, thrusting the workpiece inward against an opposing clamp and downward against the face plate or table. The result: a single powerful claming action easily applied and controlled width no slippage regardless of the load.

Obstruction is minimized, since the overall thickness of the clamp enables the workpiece surface to the machined as low as ¼” off the face plate or table. Additionally, there are no tools to interfere in the working space.
Counter Clamps
You no longer need to use improvised and haphazard stops and locating devices. The counter clamp, a J&S exclusive, assures a reliable, standardized alternative.

IN and DOWN adjustable clamping action is provided at both ends of the workpiece, insuring that the workpiece will be totally stabilized during the full machining operation.

Our entire line of J&S all purpose “Double Action” clamps are constructed from hardened and blackened steel.  A special process designed to retard breakage and prevent flaws guarantees a long life for each clamp.
