Steel Coupling Nut 10

ISO 898-2 property class 10 hexagon coupling nuts to DIN 6334. High-strength rod couplers for class 10.9 stud and threaded-rod assemblies. Long hex sleeve, metric coarse, listed M5–M20. Not a substitute for a pretensioned HV bolt set.

Use only with 10.9 rod or equivalent high-preload studs. Confirm coating practice for class 10 parts. For structural pretensioned connections, HV bolt sets — not coupling nuts — are the specified system.

Include sizes, quantities, coating, and destination. Matching 10.9 threaded rod and class 10 nuts can be quoted together.
