Hold Down Clamp, 2 Pack 20mm Woodworking Clamping Set Dog Hole Quick Acting Hold Down Bench Adjustable Desktop Clip Fast Fixed Clip Clamp

Fit my MFT style workbench very nicely. Nice snug fit.Smooth operation in the clamp. Would have been ice if they were a bit deeper by done for 95% of what I do.

My first impression was that they are smaller than I expected. They could do with a longer stem to allow clamping deeper workpieces. In fairness, the stem is secured with an allen screw and so could be exchanged with a longer one. The cam clamping mechanism is great and allows for an adjustable and solid grip.

I bought 2 of these from different suppliers and noted minor differences in the diameters but not enough to affect use. In use they are quick and easy to use and hold the wood firmly. The screws on one clamp needed tightening after limited use but was easily tightened up. Some screw lock glue will sort that problem if it happens again. Overall, I find these a useful addition to my clamping options. Are they worth £20 each? Probably, but they could be cheaper.
