ISO 898-2 property class 10 hexagon cap nuts to DIN 1587. Matching dome nuts for class 10.9 assemblies that still need a closed, personnel-safe thread end. Listed M4–M24. Confirm protrusion length: an over-long 10.9 bolt will bottom in the dome before clamp is reached.
Use only with 10.9 male fasteners. The dome geometry still limits engagement — if the joint needs full class 10 proof load and a long protrusion, a standard hex nut plus a thread protector may be clearer. Coating of high-strength parts should be specified with care.
Include sizes, quantities, coating requirements, and destination in your quote request. Matching 10.9 bolts can be added.
