Monel K500 Fasteners
Monel K500 Fasteners are threaded and non-threaded fixing components manufactured from UNS N05500, a nickel-copper alloy strengthened by aluminium and titanium additions through age hardening. The alloy contains nickel (63–70%), copper (27–33%), aluminium (2.3–3.15%), and titanium (0.35–0.85%), delivering yield strengths two to three times higher than Monel 400 while retaining the same excellent corrosion resistance in seawater, acids, and alkalis.
Alloy K500 fasteners are available as bolts, nuts, screws, studs, washers, and anchor bolts. UNS N05500 fasteners are reliable in seawater immersion, hydrofluoric acid, sulphuric acid, and alkaline conditions without any additional coatings. Monel K500 fasteners combine high strength with non-magnetic properties and outstanding marine corrosion resistance, making them the preferred specification in offshore oil and gas, marine engineering, naval, and chemical processing applications where mechanical load and extreme corrosion resistance are required at the same time.
Monel K500 Fasteners Price
Monel K500 fasteners have the same excellent corrosion resistance as traditional nickel-copper alloys, but they are three times stronger than standard grades. Prices for these fasteners vary from ₹500 to ₹3,000 per piece, depending on type, size, and finish.
Price Per Unit / Kg
The per kg price of Monel K500 fasteners falls between ₹2,000 and ₹6,000 in the Indian market. International prices track LME nickel rates very closely, as Monel K500 is predominantly nickel (63–70%) with copper, making it sensitive to nickel commodity market movements.
Factors Affecting Price
Nickel and copper dominate the cost. K500 contains over 90% combined nickel and copper. Age hardening adds manufacturing cost above standard alloys. Grade certification, thread form, surface finish, and order volume influence final pricing. Bulk orders from a verified Monel K500 fasteners supplier deliver better rates.

How to Choose the Right Monel K500 Fasteners Supplier?
Before procuring the Monel K500 Fasteners from any supplier, refer to the following pointers, as they will help you to reconcile your material needs and purchases as per the requirements of your project.
Supplier Selection Criteria
Verify the supplier can provide mill test certificates with full heat and lot traceability for UNS N05500. Monel K500 (alloy K500 fasteners) is frequently misrepresented or confused with Monel 400 in the market. Confirm the aluminium and titanium content on the MTC, as these are absent in Monel 400. Always request EN 10204 3.1 as a minimum; EN 10204 3.2 is required for offshore and naval specifications.
Technical Considerations
Confirm thread standards before ordering DIN metric for standard industrial procurement, ANSI/ASME for offshore and EPC contracts. K500 is an age-hardened alloy; confirm whether the supplier is providing material in the hot-finished-and-aged or cold-drawn-and-aged condition, as this affects final mechanical properties. For sour service, verify NACE MR0175 hardness compliance before installation.
Quality & Certification Check
Prioritise suppliers with ISO 9001:2015 certification and third-party inspection capability from SGS, BV, TUV, or Lloyds. For naval and defence applications, AMS 4676 certification may be required; confirm availability before ordering. Age treatment records and hardness test results should be included in the documentation package for every heat supplied.
Procurement Tips for Bulk Orders
Identify a vendor-qualified Monel K500 fasteners supplier for continuing procurement to eliminate quality verification overhead on each purchase. One specialist source for all sorts of UNS N05500 fasteners means less paperwork and better pricing for this high-nickel alloy. When buying for the first time, get MTCs and prices from 2-3 sources to confirm the material and set a good market baseline.
What industries use Monel K500 Fasteners?
Monel K500 Fasteners are used in offshore oil and gas, naval and marine engineering, desalination, chemical processing, OCTG downhole equipment, pump and valve manufacturing, and electronic instrument assembly industries, wherever both sustained seawater corrosion resistance and high mechanical strength are required from a non-magnetic fastener material.
Monel K500 Fasteners are threaded and non-threaded fixing components manufactured from UNS N05500, a nickel-copper alloy strengthened by aluminium and titanium additions through age hardening. The alloy contains nickel (63–70%), copper (27–33%), aluminium (2.3–3.15%), and titanium (0.35–0.85%), delivering yield strengths two to three times higher than Monel 400 while retaining the same excellent corrosion resistance in seawater, acids, and alkalis.
Alloy K500 fasteners are available as bolts, nuts, screws, studs, washers, and anchor bolts. UNS N05500 fasteners are reliable in seawater immersion, hydrofluoric acid, sulphuric acid, and alkaline conditions without any additional coatings. Monel K500 fasteners combine high strength with non-magnetic properties and outstanding marine corrosion resistance, making them the preferred specification in offshore oil and gas, marine engineering, naval, and chemical processing applications where mechanical load and extreme corrosion resistance are required at the same time.
