Frequently Asked Questions
What's the difference between Monel 400 and Monel K500 fasteners?
Monel 400 is the standard, lower-cost grade for general corrosion resistance in chemical, marine, and acid service. Monel K500 is age-hardened for roughly double the tensile strength, at a 30–50% cost premium, and earns that premium on high-load or wear applications like shafting and pump components. See our full comparison on the Monel 400 Fasteners page.
Which Monel grade should I use for marine fasteners?
Monel 400 covers the vast majority of marine fastening needs — seawater piping, deck hardware, and general corrosion resistance. Reach for Monel K500 specifically when the application also carries a real mechanical load, like propeller shafting or pump hardware.
Do you supply custom or coated Monel fasteners?
Yes — custom head marking, thread locking compounds, and surface coatings are all available on request, in addition to standard mill-finish fasteners.
What is the minimum order quantity for Monel fasteners?
We run zero MOQ across both grades. Standard sizes are ex-stock in Mumbai for fast dispatch; anything outside standard stock is manufactured to order with no minimum quantity requirement.
What certificates come standard with Monel fasteners?
Every order ships with an EN 10204 3.1 mill test certificate. PMI, third-party inspection (TPI), and NABL-accredited lab reports are available on request for critical applications.
What is the HS code for Monel fasteners?
Generally 7318.15.00, though it's worth confirming the exact classification with your customs broker since it can vary slightly by destination country.
What industries typically use Monel fasteners?
Chemical and petrochemical processing, oil and gas (including sour service), marine and shipbuilding, and defense/aerospace account for the large majority of demand, with occasional specialty use in coastal construction hardware.
What payment and delivery terms do you offer?
We accept LC, TT/wire transfer, and cheque, with export-grade packaging and dispatch from Mumbai or Kalamboli ports. See the Packaging, Payment & Delivery section above for details.
