Details

ThunderHex Stock works in all applications where 1/2" Hex Shaft will work and also includes rounded corners. These rounded corners allow the shaft to pilot inside a 13.75 mm round (ThunderHex) Bearing instead of a standard 1/2" Hex Bearing. This eliminates some difficult manufacturing tolerances and results in a MUCH smoother end result. Simply put, ThunderHex Bearings are the best way to create smooth-running hex shafts, and ThunderHex Stock helps you accomplish this without a lathe.

Also, since you're essentially putting a round peg in a round hole, no more struggling to align the hex of your shaft with the hex hole of your bearing.

The 0.500" hex bearings (217-2734) have been updated for the 2015 season to a version 2 (217-3875). This bearing features a larger inner race for additional strength and durability.
