Climax Metal 2C-125 Steel Two-Piece Clamping Collar, Black Oxide Plating, 1-1/4" Bore Size, 2-1/16" OD, With 1/4-28 x 3/4 Set Screw, 1 Count

I used this to make a depth stop for a vintage drill press. I'm not sure what some other reviewers were using them for. Well made and not zinc-plated, which was nice for welding without poisoning myself or spending time removing the plating. The cap screws that tighten are ASE (3/16") hex wrench, which is nice as it matches my drill press--fewer tools. It welds and tools well. It's concentric and fits the advertised size perfectly. No complaints!

Its exactly as described. I was hoping it was bigger, but that was my bad. solid steel

It functions well but comments from other reviewers about rust seem to be true. I swear, just looking at it causes to rust.

I am using this collar to hold a lampshade on a socket that does not have any threads or a not.

I'm using this on an old office chair with a completely ruined lift mechanism. It prevents the inner metal shaft of the mechanism from sliding all the way through the hole in the base. It's not the prettiest solution, but it's cheaper than buying a new chair or a new lift mechanism. Obviously the disadvantage is that it's not very convenient to adjust the height, but a fixed height is fine with me.

First, I would like to thank Climax Metals for their professional customer service. This was an international shipment to southeast Asia. Not only did the item arrive safe and secure, but I got my order ten days earlier than expected! So again, thank you Climax Metals for your service. Others could learn from you. That said, the collar is very well made and provides a great example of adaptability of modern technology to holistic health techniques. It will likely require some practice placing the collar so as not to nip or injure the skin. But with a little patience and making sure you have the correct size, you should do well. And one last point, you will need a T30 torx screwdriver to secure the screws in place. Good luck and stay healthy!

The device is nice but it rusts and tarnishes. The bolts also rust and can be very difficult to tighten/loosen without a tool. Definitely something enjoyable but will need a replacement very soon after wearing. Time for an upgrade.

I needed something that could hold to the vibration of a 2-stroke engine as the clamp holds essentially what is the intake manifold. I used my rotary tool to bore it out slightly more as the next size up would of been too big. It wasn't impossible with double cut carbide bits, but the metal is definitely hard and dense. Physically speaking, it isn't cheap. If I ever need any sort of collar shaft I will return to this seller.
