Wilton MMS-12 12 in Mini F-Clamp

The Wilton MMS-12 is a 12 inch mini F-clamp built for automotive, metalworking, plumbing, welding and woodworking tasks. Its extruded steel bar measures 7/16 inch wide by 1/4 inch thick and delivers a clamping force of 400 lb. A 2-1/4 inch throat depth and swivel jaw pads allow secure grip on irregular workpieces. The steel handle provides leverage for tightening in confined spaces.

Check workpiece thickness and reach before ordering

Verify that the 12 inch clamping capacity matches the maximum thickness of the material you intend to hold. Confirm the 2-1/4 inch throat depth is sufficient to reach the clamping point from the edge of the workpiece. Ensure the 7/16 inch bar width and 1/4 inch bar thickness fit within the available clearance of your fixture or assembly. The swivel jaw pads adapt to non-parallel surfaces but require flat contact areas to develop full force.

Sustained load behaviour with 400 lb force

Under continuous tightening the extruded steel bar resists deflection while the swivel pads maintain even pressure across the joint. The 400 lb clamping force holds glued or welded assemblies without creep during cure or cool-down cycles. Steel construction prevents handle slip when vibration occurs in machining or welding operations. The fixed throat depth keeps leverage consistent so repeat set-ups achieve the same force each time.
