Used to space components axially on both ½ inch and ⅜ inch hex shaft. The spacers vary in length and can be combined to achieve precise spacing down to a 1/16 of an inch.
The spacers are designed to easily slip over a hex shaft however the bore is round. The round bore allows you to easily align the spacer on the shaft. No more spending hours trying to get the hex to align on the last 1/16 spacer on your drive train axles.
