2pcs 7 x 7mm Motor Shaft Rigid Brass Sleeve Coupling Connector + Tighten Screws

Very nice. The fit is accurate and seem of high quality brass. with enough clearance for a 7mm shaft. I like the thickness and the fact the set screws are below the surface and not sticking up like some I have used. I used these for an epoxy turner in conjunction with flange coupling. I was very impressed with the quality.

I purchased these couplers for a special application. Although they didn't work out for me, they were excellent quality.

Great buy

I used one of these to repair a motorized animated deer (a Winter decoration) whose motor had failed - the replacement shaft was the right diameter, but did not extend far enough out of the housing.These couplers are pretty thick, so the set screws have plenty of threading to work with. Each coupler supports four screws, and two couplers were included in the package, along with a suitable allen wrench, ans shown.I only wish I could have found some that were shorter - my repaired assembly is about 1/2" taller than I'd like - but that is not the fault of these couplings.

There are two sets of set screw holes in each sleeve body (and enough set screws to fill them).

Muy buena calidad de material

This coupler was used to connect an extension shaft to the shaft on a new motor for a ceiling exhaust fan which now works. The only problem is I needed only 1 and it came as a set of 2. The 2nd one is now occupying a baggie in the bottom of my toolbox.
