About Brass Metric Thread

The most common thread type in production today. Usually specified as M then a number x another number. This signifies the thread diameter and the length of the fastener.

For example, M4 x 30 means that the major thread diameter (the external distance across the outside of the thread) is 4mm and the length is 30mm. Length is usually measured from the underside of the fastener head.

Brass is an alloy that is made of copper and zinc. It does not corrode easily and gives an attractive, decorative finish when used to make fasteners.
