If a nut or bolt will not come loose, reaching for a bigger wrench may be the worst thing to do!

Sooner or later, the classic bike owner will come across a left-hand thread. But can you identify a thread by just looking at it? Yes, by following this simple tip, you will be able to glance at the threads and know straight away which type they are - left or right handed.

The identification process is simple: if the threads go up to the left, they are left hand threads; conversely, if they go up to the right, they are right hand threads.

This tip will stop you from snapping the head off of left handed bolts.
