## Questions & Answers

**Q: I have typical US made dumbells but they're about 1 and 1/16 diameter.  Is this diameter collar available anywhere?**
A: They do make them. I would just Google 1 1/16” shaft collar.

**Q: So these measure one inch inside bore diameter?**
A: Mine are one inch on inside.

**Q: Will this fit an Olympic bar as a spacer?**
A: It depends what the diameter of an Olympic bar is.  I do not know.  I used these to slid onto a 1” diameter metal rod and it was a very very tight fit.

**Q: Can you use these on a dumbell where the inner collar came loose ?**
A: For safety reasons, I'd try one and see how it works for your purpose. I've seen too many such collars fail from becoming loose with usage.

### ⭐⭐⭐⭐⭐ Caution: Will not fit ALL so-called “1-inch bars.”
*by R***T on February 24, 2022*

I can’t fault the seller that these collars didn’t fit on all my 1-inch bars. The specs are posted. However, it seems not all 1-inch bars are exactly 1-inch in diameter after all.I used these Climax collars on an old EZ-curl bar with threads/collars worn so badly they no longer tighten down completely. Also, one of the plate stops had come loose over the years.I used one on each side to make the weight-plate placement equal, and another one on each side to keep the screw-collars from backing out — four in all, and saved me the cost of buying an expensive new EZ-curl bar. Although fitting easily on that bar and another older threaded type bar, they were too tight on my newer, threaded dumbbell bars and on my older slide-collar type bars. The original collars for the latter measured about 1.050”. Obviously, these Climax collars weren’t designed for this particular 1-inch application in the first place.They also didn’t fit over the 1-inch round rolled-steel bar stock I’d used on my old homemade cable lat low-row machine built 28 years ago. I measured these bars with precision dial calipers (0.001” accurate) and discovered that they are not perfectly round, hence not precisely 1-inch in diameter. Varying by plus or minus 20 thou, depending on the point of measurement. This also proved to be the case with the older slip-on collar type barbell and dumbbell bars. I decided to try drilling them [collars] out to 1/32” over with an electric drill, my drill press being broken, but the attempt failed. Bad idea!A better one was to use a high-speed rotary grinder and grinding stone. This took a few minutes for each collar but worked well enough and didn’t really cost me anything except a little time. Despite that minor hassle, these are excellent quality collars. I’m now using them on several threaded bars to prevent the damned screw-collars from coming loose all the time.Although they’re not going to work on every so-called 1-inch bar, for me they turned out to be a decent deal considering there’s not much more than high-priced options of dubious quality [plastic] out there these days. They require a 5/32”, or 4mm Allen key for the set screw.

### ⭐⭐⭐⭐⭐ Set screw is not 5/16-18, it is 5/16-24
*by D***. on October 13, 2024*

Quality of the collar is nice, it has a clear zinc finish. The set screw (grub screw for our UK friends) is actually 5/16-24, not 5/16-18. I see not only is this listed wrong in the product headline, but the attached dimensioned drawing also gives the wrong 5-16-18 thread. If you search for the C-100 collar at the Climax Metals catalog you'll see the correct 5/16-24 thread specified. The set screw has the expected 5/32" internal hex, and the finish looks like a black phosphate so this won't hold up well in a wet application. Decent product, I wish the country of origin was listed.

### ⭐⭐⭐⭐⭐ Shaft  Collar
*by L***Y on March 9, 2025*

Perfect to suit my application.
