A few years ago I purchased 4 bar clamps from Harbor Freight, the cheap ones that arnt much good for anything, but they were cheap and I dint know much better. After a few minutes with them in the shop and I found out just how “cheap” they really were. Since then I’ve aquired much better clamps and the HF clamps were in the “just in case pile”. The other day I went to use one and the frist one I grab the handle breaks off in my hand, I toss it aside finish clamping my project and went to inspect the pieces of the clamp. Thinking that I was gonna trash the thing anyway I went to dismantling it. I instantly found the problem, the small plastic pins the handle pivoited on sheared off under the pressure of my squeese. Looking at the rest of the clamping mechanism it was sound enough seemed a shame to just toss it so i went to fixin it.

Start with removing the screws from the side of the clamp.

Drill a 3/16 hole through the center of the pins that hold the orange handle.

Place a 10-32×3/4 machine screw through the back, through the handle,

replace the cover and screws add a nut to the machine screw and your finished.

Seems like something HF could do cheap and easy…

I’ve done that and the next time I squeezed the handle, the top jaw snapped off! I’m not buying or repairing any more!

Those HF clamps are a bunch of crap. I had several and the had virtually no clamping pressure and could hardly squeezr glue out of a joint. They also broke very easily.

I also made the mistake of buying a few of those and regret doing so. Never again.
