look nice and shiny. Are the right size for 1/8" shaft. Comes with an allen wrench so no need to search for your own. Have bought dozens of these and will buy more in the future.

These are the correct outer diameter for Petersen 3D printer clocks. Others have a larger outer diameter and won’t fit into the printed parts. These worked like a champ!

Dubro has been making small RC parts forever. I can depend upon them to deliver high quality tires and parts without breaking the bank. These collars were no different. All of the set screws fit perfect, with no thread defects. Finish and sizing on the collars was right on. Go with Dubro….

When the set screw on the throttle linkage for my outboard motor stripped - - I used two of these locking sleeves (one) on each side to hold it in place.

I can't really say much about them except they are as described. They seem sturdy. I was nervous about losing the super tiny screws so I put them on a small rod (rod not included) to keep them together. Also keep in mind the screw has a slight over hang.

Very nice product, but the hex key that comes with it is prone to twist due to its small size.
