Lock Nuts - BSW Left Hand

Sometimes written as lock nuts, they also go by various other names, including half nuts, jam nuts and thin nuts.

Locknuts are used to lock a full nut in position to prevent it from working loose as a result of vibration or other factors. A common area in which lock nuts are used is on car wheels.

Locknuts are often mixed up with Nyloc nuts, which are different. Nyloc nuts are self-locking nuts that feature a nylon collar in the top portion of the nut that locks the nut in place.

About BSW Left Hand Thread

BSW (British Standard Whitworth) is an imperial coarse thread first used in standard production by Joseph Whitworth during the industrial revolution. Whilst it is still used in engineering applications all across the world it is less common in the UK where metric threads have generally taken over.

A left hand thread is the terms used for a thread where the nut tightens in the opposite direction to normal. It is commonly used on items that rotate in a manner that could cause a normal right handed nut to loosen, for a example the pedal of a bicycle on the left hand side.
