Dimensions in mm to DIN 6923. Flange nuts use a smaller width across flats than standard hex nuts. Sizes and tolerances are made to your drawing on request.
Applications
Typical applications for the Brass Hex Flange Nut include sheet-metal and bracket fastening without a loose washer, automotive and chassis assemblies, enclosure and panel mounting, and busbar / rack bonding. As all parts are made to order, sizes, threads, plating and certification are tailored to your specification.

Frequently asked questions
A DIN 6923 nut has an integral flange (a built-in washer) at its base; a DIN 934 nut does not. The flange spreads load and resists loosening.
No — the flange acts as the washer, spreading the clamping load over a wider bearing area.
Both forms exist. A serrated flange bites into the surface for extra vibration resistance; specify which you need at quotation.
15 mm — flange nuts use a smaller width across flats than standard hex nuts of the same thread.
