    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.

    Annoyed by the nut coming loose every time I put them down I resorted to this collar and voila, the plates have not moved in 3 sessions.

    I got a few to fit around a standard 1 dumbbell bar as weight collars. It fits perfectly on all the standard bars I have and tightens down tight and secure. I dont worry about scratching my dumbell bars but if I did theres other style shaft collars that screw around to tighten like pipe clamps.

    I liked the body of the of this shaft collar, and the only reason for the 3 stars is the threads as stated is wrong. I ordered thumb screws for these and it turned out that the set screw is 5/16-24 and not 5/16-18 as stated. It turns out that 5/16- 18 would have been better as there are more options in the size thread.
