Monel K500 Bolts are non-magnetic and stronger than plain Alloy 400. Drilling tool makers often prefer them for this reason. Oshwin Overseas is a trusted Monel K500 Bolts manufacturer in India. The company is based in Mumbai and works to ASTM B865 UNS N05500. Stock includes Alloy K500 nuts, socket head cap screws, U-bolts, hex bolts and threaded rod. These UNS N05500 bolts get their strength from precipitation hardening. Oshwin exports to Netherlands, Nigeria, Qatar and Thailand.
Age-Hardened to F468

Monel K500 Bolts Specification
Aging is the step that sets K500 apart from Monel 400. Bar stock draws down, ages near 1100°F, then heads and threads at our Mumbai plant. The higher hardness after aging shifts our cold-heading limit lower than on softer nickel-copper grades.

ASTM F468 UNS N05500 Chemical Composition
Per ASTM F468 UNS N05500. Aluminium and titanium are the two elements that separate this grade from Monel 400. Full heat-wise composition rides on the EN 10204 3.1 certificate.

Request Export QuoteNickel-Copper-Aluminium K500 Bolts Galling & Anti-Seize Torque Guidance
T = K × F × d stays the torque formula for K500 too. K, the friction coefficient, is the only part that changes with the alloy. Clamp load (F) and diameter (d) come from your joint design, not the material. Aged nickel-copper-aluminium threads push K higher unless they're greased.
Galling Risk
Dry-fitted K500 threads gall fast - lubricant is non-negotiable
Anti-Seize
A nickel-rated anti-seize paste prevents seizing on assembly
Torque Formula
T = K × F × d - K drops with the anti-seize you choose
Buyer-Specified Torque
Send your clamp load and we'll match it, rather than quoting a generic figure

FAQs - Monel K500 Bolts
F468 covers finished K500 bolts, screws and studs in the aged condition. B865 covers the raw bar and rod stock. We machine F468 fasteners from certified B865 bar, one heat, one certificate.
Minimum yield of ASTM F468 aged condition is 90 ksi up to 7/8 inch dia. It drops to 85 ksi from 1 to 1-1/2 inch. Minimum tensile is 130 ksi.
Monel K500 bolts and nuts are stronger, about 90 ksi yield vs 40 ksi for Monel 400. Use K500 for pump shafts and high-load studs. Use 400 for easier welding and lower cost.
K500 bolts and nuts stay non-magnetic down to about -150°F. Surface processing can leave a thin magnetic film and pickling or bright dipping removes it.
Yes. Nickel-copper-aluminium threads gall under dry torque, same as Monel 400. Use a nickel-rated anti-seize on every joint and share your torque target with your inquiry.
Ex-stock: M5 to M36 metric, 1/4 inch to 1-1/2 inch UNC/UNF. Grub screws and socket head bolts run smaller, other sizes made to drawing.
Yes, though they're different specs. B865 covers raw bar stock. F468 covers finished bolts and studs, machined from the same certified B865 heat.
Price depends on size, quantity, thread form and head style. Share your spec on WhatsApp or by email and we'll return a firm ex-Mumbai quote the same day.
