Flange Nuts - BA

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.

BA thread (British association) is a rarely used thread that was once commonly found on small instruments and models. Still sparingly used in some industries such as metering equipment manufacturing and optical equipment.
