BGS TECHNIC Ring spanners and wrenches for motorcycles

You'll find ring spanners and open spanners in every handyman's toolkit. These spanners are used to tighten or loosen nuts and bolts and come in various sizes, both metric and imperial.

A socket wrench 'grips' the parallel, overlapping sides of a nut or bolt, while a socket wrench utilizes all the angles of a nut or bolt.

The larger the bolt to be tightened, the greater the tightening torque allowed. In order to achieve this effect anyway, socket wrenches become longer as they grow in size. The larger the size, the longer the handle, in other words. Voilà, now you may have learned something new.
