How to measure a Bolt or Axle
TBolt USA Tech Database!


Industry standard practice is to measure the shaft of the bolt NOT the HEAD 

All of the Bolts and Axles we offer are measured this way

One easy way if to put the open end of a wrench on the shaft
a 15mm open end wrench will fit a 15mm axle shaft
