How heavy duty are these actually?? I've ruined over a dozen lowes brand clamps in the last year cause the threads strip out.

You won't strip the threads on this one as long as you are tightening with your hand.
2086292
you will not destroy these unless you're misusing them...heavy and well made as fitting the Jorgensen name.

I cannot answer in ft./lbs but..they are quite heavy duty even compared to Jorgensen medium duty clamps. These could even be used in some construction applications (and I have) instead of pipe clamps. For woodworking glue-ups, they are more than enough.

It is heavy duty. They are not comparable to the plastic Lowe's clamps. Both the orange and silver components in this picture are solid metal on the clamps I ordered.

I have several of the standard duty Jorgensen clamps in this size. This one is definitely heavy duty in comparison.

Two things. First, I have had Jorgensen heavy duty clamps for years (decades, actually) and they have never failed. You can crank them to the limits of your own muscles. They are truly heavy duty. Second, I have been to several woodworking schools around the country. These are the clamps they use because they work and don't break. Clamps like Bessey's are pretty, but getting parts when their more complicated mechanisms fail is hard and irritating.These clamps are made in the USA and worth every penny.

They are very strong. I cannot can see how anyone could over torque in normal use. I am very happy with mine

I don't know. They look generic. If the company won't/can't replace them, I'd try a spring manufacturer. If you google "heavy duty springs," you will get several possibilities.

I'm not the most knowledgeable to answer this but the quality of the rings are good. I have had no problems with breaking or threads stripping if that's what you mean. They also hold finger tight on my 22.

They are really hard to crimp. Even using the proper crimper. Without them you wont get even pressure and probaby spring leaks in the future. Also the real crimper ratchets so if you have to change your grip on it, it wont release the clamp. Basically the extra 55 bucks is totally worth it.

Use a plastic screw (food grade and high temp suitable - e.g. for water lines) - that is the best option I can give you. The threads seems to be non-standard.You should also try getting the correct nuts from the seller.

I have never had a problem. I just make sure they are tight with no play when wrapping the velcro around the posts. I bought mine in 2011 so can't say if there have been any design changes in the interim which may have led to a lower strength velcro.

The threads are very sturdy 1/2 inch coarse with a nice wide flange nut on each one. I didn't need any other hardware. The bolts aren't super long - maybe 1 1/2 inch. I didn't measure. These bolts fit my woodworking equipment stands perfectly and do a great job. They lock well and swivel well... I highly recommend them.

I have used these clamps for many years and have never seen or heard of a problem with them staining wood. I suppose that, if there were residual stain material on the clamp, it could be transferred to the work. That, I would classify as operator error.

I replaced my ground clamp with a US Forge Bronze clamp. Is sold by Amazon. I have had no problems with since I changed.

The threads on these compressors are subject to a lot of strain and sheer and I note no deformation in the threads after use. I'm willing to use these very same compressors in future projects.

They came with some replacement clamps, but I just reused the original ones. If that doesn't work, maybe ask to see if the seller could replace them.

They are really heavy duty.. you shouldn't have a problem in my opinion. I've had them on a chair for almost a year, and they are great!

The threads are fine. 1/2 in. bolt 20 threads per inch. Just like the picture. Thanx to all the people who said coarse thread now i have skids that wont fit.

The bolts worked fine for me, but they are holding up light swinging doors that go to a small pattio. I would call them heavy duty but each application is going to be different. the bolts are less than 1/2 inch. The nice thing about them is they come with a grease fitting on the bottom.

Yes they will maintain their finish they should not rust at all very beefy clamps! I would use them in a shower

They are solid and heavy like home Depot. One handle did have bad threads in one of the mounts but the other 24 were fine! I would recommend them.

Thanks all for your input. I ended up going to OSH, matching the thread, then purchasing 1" bolts instead of 1.5" bolts that was supplied in the packaging. So new purchasers, save yourself a bunch of anxiety and buy yourself 1" #8 32 standard thread. I e-talked with the manufacturer, Progress Lighting. That was pretty useless...community, you were much more help! Thanks...
