Fasteners
Serrated Flange Nuts — DIN 6923
Cold-formed flange nuts with serrated bearing face for vibration resistance without a separate washer.
SpecificationsOur DIN 933 hex head bolts are cold-forged from low-carbon boron steel and hardened to the requested property class, then finished to your plating specification. Every production lot carries a heat number that traces back to the steel mill certificate, so a dimensional or metallurgical question three years from now is answerable in minutes rather than weeks.
