Review on Lovejoy D4B Universal Setscrew Diameter by Trey Michaels

Probably should have known how to install this item on the shaft. There were no instructions for it at all. After finding out that it was slightly less bored than the 3/8" shank I had, I figured it needed to be heated to expand it so it would slide onto the shank. Anyway, I did made and then lubricated. From the moment it was heated the factory grease burned out. For the quality I still give 5 stars. Very well made and should last a lifetime.
