Flange Nuts - UNF

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 that prevent the nut from turning in a loosening direction.

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

UNF stands for Unified National Fine. It is a common imperial thread type with more threads per axial distance than its UNC equivalent.

Unified thread types (UNF and UNC) were introduced at the beginning of World War 2 to enable the interchangeability of machinery manufacturing between the USA, Canada and Great Britain. Still commonly found on a vast array of old machines and vehicles in the UK, UNF and UNC threads continue to be the standard thread in the USA and Canada.
