Flange Nuts - Metric

M6 - Flange Nut Hexagon DIN 6923 Serrated Grade 8 - BZP - Pack of 100

A flange nut is essentially a hexagon fullnut with an integrated washer. The flange provides an additional surface area that spreads the pressure from the nut, reducing the chance of damage.

The underside of the flange has angled serrations which prevent the nut from turning in a loosening direction.

Metric flange nuts are manufactured to the European Din 6923 standard.

Metric is 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.
