Cam Action T-Track Quick Release Hold Down Clamp for Jigs, Fixtures & Shop Fences. Ideal for Router and Drill Press Table Fences (1, 3/8")

I used them to bolt a vice onto a drill press so I could adjust it's position. They worked great for that purpose and the threads are standard if you need to switch out the bolts they come with. They only complaint I might have had was with the price. At my time of purchase a two pack of these cost more than a 4 pack of very similar product from competitors. But these do have beefier bolts in them than any others I found on amazon at the time of review so if your use is for more industrial environments these might be the better option.

Over spun it a bit, put some pressure and the handle broke on my first use. Might hold down a feather pretty well.

These clamps are very sturdy

The plastic washer split into two after about 50 uses. It still works without it; but much differently in a not-better direction.

Unlike the Rockler on the right this cam clamp is not fully rounded rather it utilizes a flat spot to lock it in place which made it difficult to find the perfect setting in my application.

It was exactly what I was looking for when I was building a stop rail for my miter saw.

I have been using this on a Stitching pony I made for stitching leather goods for over a year. What a pleasure. Before that I was using a rotating knob but this works so much faster and has held up very well. I use my stitching pony at least 4 days a week.

Maybe I got a faulty one, but my cam snapped in half after applying what I thought was not a crazy amount of force. I believe it was rated for 400lbs, but I did not apply that much force. On a positive note, for light use, works great. High precision aluminum.
