Steel classes
Nut property class is selected to suit the mating bolt and joint requirement.
Hex flange nut sourcing
Metric hexagon flange nuts with an integrated bearing flange for bolted assemblies, matched to the specified standard, thread, flange-face requirement, property class, material and finish.
Catalogue ranges are RFQ guidance. Final compliance is controlled by the buyer-approved standard, drawing, flange-face requirement, sample and purchase order.
Quotation control
The exact standard or drawing, thread, flange face, material, finish, quantity and destination are confirmed before sourcing.

Product overview
Hex flange nuts combine a hex driving body with an integrated bearing flange. Thread fit, nut property class, flange geometry, plain or serrated bearing face, material, finish and coating compatibility must be reviewed with the mating bolt and service environment.
DIN 6923 remains a widely requested designation. ISO’s official catalogue states that ISO 4161:2012 covers style-2 hexagon flange nuts with metric coarse threads M5 to M20, product grade A through M16 and product grade B above M16. XHT does not assume that DIN 6923, ISO 4161 or a drawing can be substituted without buyer approval.
