Q: How much clamping force does this cam clamp apply?
This cam clamp mechanism (5/16-18 thread) can apply up to 400 lb of force from a simple push of the handle, using only a thumb and forefinger to lock or release it.
05J5105 - 5/16-18 Cam Clamp Mechanism
One of the best jig mechanisms we offer, this cam clamp can exert as much as 400 lb of force using only a thumb and forefinger to operate the handle. It makes quick work of clamping and releasing jigs and fixtures, especially when doing repetitive work.
With a 3 3/8" long steel handle, this cam clamp is suitable for heavy clamping applications. The steel cross-dowel nut can be used with any fastener with a matching thread (e.g., a bolt or a threaded rod and nut). Our T-bolts are ideal.
Includes two washers of different thickness so you can choose lever orientation without affecting clamping force.
This cam clamp mechanism (5/16-18 thread) can apply up to 400 lb of force from a simple push of the handle, using only a thumb and forefinger to lock or release it.
The 5/16" cam clamp needs 9/16" to 3/4" of exposed stud; too little and the cross dowel won't engage, too much and the handle will catch.
Yes, the two included washers are sized so that adding or removing one flips the handle's locked orientation 180 degrees without changing the clamping force.
No, pressure should be adjusted gradually since this clamp can apply enough force to damage the jig or the workpiece being clamped.
Add extra washers, available separately, onto the stud to shorten the exposed length before threading the handle back on.
