Bolt M12x40 1318/0510Z JCB, genuine

Bolt M12x40 1318/0510Z is a genuine JCB part for the JCB machines. According to the product card, this part is a bolt, size M12x40.

A bolt is a threaded fastener that clamps two or more parts together and holds them in place. The strength of the joint depends on the preload created when the bolt is tightened to the correct torque: the bolt stretches slightly and presses the parts together like a spring. A loose bolt works under vibration, ovals its holes and finally breaks from fatigue, while an overtightened bolt yields and loses its thread. On machines, bolts are therefore tightened to the specified torque and checked regularly.
