VEXpro offers several different lightweight shaft stock options made from both 6061 aluminum (for tube axles) and 7075 T6 Aluminum (for high-strength hex shafts handling torsional loads). These shaft lengths are correctly toleranced such that they fit perfectly through bearings and hubs, without extra work.
While it's tough to get excited about a few pieces of shaft stock, these shafts are specifically created to reduce user frustration. Do yourself a favor, buy some of the good stuff. •7075-T6 Aluminum (3/8" & 1/2" Hex) •6061-T6 Aluminum (1/2" Tube) •Black anodized •18" or 3' lengths
Note: Due to a manufacturing variance, our current inventory is slightly out of tolerance. The diameter of our 18" ThunderHex Stock is oversized by (on average) 0.0003". This results in a press-fit into ThunderHex round bearings. Users who need a looser fit should gently sand the rounded corners of the hex.
