ONE ALLOY. TWO ASSEMBLY TYPES.
Specify the geometry. Not a substitute.
Higher-strength nickel-copper bolting. Defined by the specification.
Monel K-500 adds aluminium and titanium to the nickel-copper alloy system, enabling age hardening. The material condition matters as much as the alloy designation: it determines the properties your joint design relies on.
Full-thread or double-end geometry, thread engagement, overall length and matched nut requirement. Include your drawing revision, service conditions and acceptance criteria. EMG manages supply through qualified manufacturing partners, with feasibility and records agreed before order.

THE WHOLE JOINT MATTERS
Bolt. Nut. Condition. Evidence.
Matching markings are not enough. Specify the nut alloy, thread fit, proof or mechanical requirements, and inspection scope as part of the complete assembly. Monel 400 nuts are not an automatic substitute for K-500 nuts.
Sour service requires a separate review.
No blanket NACE approval is implied. Your materials engineer must assess condition, hardness, environment and applicable NACE MR0175 / ISO 15156 requirements. Subsea and cathodically protected applications also require project-specific assessment.
