Tight thread tolerance matters most in Inconel 600 bolting - a loose fit can mean a failed joint at high temperature. Oshwin Overseas machines Inconel 600 Bolts, Hex Nuts and Studs in Mumbai, India, to ASTM B166 UNS N06600, and supplies them to UAE, Saudi Arabia, Qatar and the USA.
Threads are held to ANSI B1.1 Class 2A/2B, with stud external thread checked against ASTM F2281. We produce hex bolts, nuts, threaded rod and stud bolts as per client's drawing. Inconel 600 resists heat and oxidation well, common in furnace and heat-treatment equipment. Each batch is machined and gauge-checked in-house before dispatch.
Oxidation resistant from cryogenic temperatures to 1093°C, no post-weld heat treatment.
Priority dispatch for furnace, chemical-processing and nuclear-grade orders.

Oshwin Overseas cold-forms and hot-forges Inconel 600 Bolts at our Kalamboli, Navi Mumbai plant. Smaller diameters stay cold headed for tighter thread control. Larger stud bolts and heavy hex sizes go through hot forging before final machining.

Request Quote NowPhotography for several Inconel 600 items is still in progress at our Mumbai facility. Every type below stays in stock and ready to quote. Head styles outside this list are cut to drawing on request.
UNS N06600 Bolts metric sizes M6 to M64 stay ready for dispatch at our Navi Mumbai stockyard. In-house custom cutting covers any length outside this range.
Lengths cut and threaded to drawing. Left-hand thread and non-standard heavy hex sizes confirmed on request.
Per ASTM B166 / AMS 5687 (Ni-Cr-Fe, non-age-hardenable). Carbon stays at 0.15% max and sulfur at 0.015% max. Full heat-wise composition appears on the EN 10204 3.1 certificate.
Inconel 600 Bolt mechanical properties center on the annealed condition set by ASTM B166. Strength does not shift with a separate heat-treatment step, unlike age-hardenable grades.
Values shown are for the ASTM B166 annealed condition. Cold-drawn AMS 5687 wire and small-diameter bar test above these minimums.

Request Export QuoteBolt torque follows T = K × F × d. F is the target clamp load, K is a friction coefficient set by the lubricant. The same formula applies to Inconel 600 as it does to steel bolting.
Nickel-alloy threads gall under dry torque - always lubricate
Use a nickel-alloy-rated anti-seize or a high-temp dry lubricant
Class 2A/2B fit keeps torque-tension behaviour predictable
We confirm your exact torque target - never a generic figure
Alloy 600 Bolts thread pitch follows standard ISO metric coarse pitch and UNC/UNF series. Threads are cut to ANSI B1.1 Class 2A external tolerance.

Nut Compatibility: Inconel 600 Bolts pair best with same-alloy UNS N06600 hex or heavy hex nuts to AMS 5665. This keeps corrosion resistance matched across the joint. A lower-alloy nut creates a galvanic mismatch and caps joint strength to the weaker nut. Our FL 33428 buyer specified matching UNS N06600 nuts and plain washers, Class 2B thread, with the bolt order.
Nickel superalloys skip the SAE/ASTM grade-line marks used on steel bolts. We trace each Inconel 600 bolt by its material stamp and heat number instead.

Inconel 600 Bolts Manufacturer in India with NACE Compliance
Cold-worked, ANSI B1.1 thread-checked stock, ready for immediate dispatch.
Get Manufacturer QuoteStock supply is only part of what we offer on Inconel 600 fasteners. Our Kalamboli, Navi Mumbai plant handles these secondary operations in-house.
Oshwin runs bar drawing, cold heading, forging and thread rolling under one roof for Inconel 600. In-house control keeps thread class consistent across a non-age-hardening alloy.
A compatible flange, gasket and nut material keeps an Inconel 600 bolted joint free of galvanic corrosion and preload loss.
Zinc plating and hot-dip galvanizing suit carbon steel, not nickel superalloys. We skip both on Inconel 600 fasteners for that reason.
Every Inconel 600 order is fully traceable, and third-party inspection is welcome at any stage.
Alloy 600 Socket Head Cap Screws are made to ASME, British BS, Indian IS, ISO and DIN standards. Size M3 through M36 stays in stock, larger sizes made to drawing.
As an Inconel 600 bolts supplier and distributor to the USA, we ship most volume there. Recent orders came from California, Florida and Thailand. We're also active as inconel bolts suppliers in Saudi Arabia and the wider Gulf, alongside Southeast Asia.

ASTM B166 covers the raw hot-finished or cold-drawn rod and bar. ASTM F2281 sets the finished fastener requirements - strength, thread class and marking. For a PO, write ASTM F2281 UNS N06600.
Inconel 600 doesn't age harden. Cold work builds its strength instead. Inconel 718 needs an AMS 5663 aging step for that. Choose 600 for easy weldability, 718 for higher strength.
Per ASTM B166, annealed condition: 80 ksi (552 MPa) tensile strength minimum. Yield strength is 35 ksi (241 MPa) minimum, elongation 30% minimum. Cold-drawn AMS 5687 wire and small bar can test higher.
Both handle chloride and saltwater well. Inconel 625 adds molybdenum, so it resists pitting even better in seawater. Inconel 600 is the better pick for high-heat jobs, like furnaces.
Yes. Nickel threads gall if torqued dry. Always use anti-seize with a calibrated wrench. Skip generic steel torque numbers - ask us for the right spec.
Ex-stock: M6 to M64 metric, 1/4 inch to 2 inch UNC/UNF. Heavy hex and non-standard lengths are cut to drawing.
Yes, even 10 pieces is fine. We ship small orders just as easily as big ones. Ask for bolt, nut and washer sets assembled together, same heat.
Go custom for a non-standard length. Same for a heavy hex outside M6-M64, or a left-hand thread. Just share your drawing with us for a firm lead time.
