Inconel 600 Stud Bolts
ASME B18.31.2ASTM B166
Inconel 600 stud bolts pair a solid-solution nickel-chromium-iron alloy with double-ended closure for furnace, refinery, and boiler joints that cycle between heating and cooling. The alloy resists scaling and oxidation.

What we can make in Alloy 600
Fully threaded
Two nuts clamp the flange or cover; usable thread length spans the assembled grip.
Double-end
A plain centre spans the grip, with a threaded portion at each end for the nuts.
Tap-end
One end engages a tapped casing; the exposed end accepts the cover nut.

Manufacturing route
CNC machining suits samples and special end forms. Repeat lots use cut-to-length stock with rolling or cutting selected for the ordered thread and material condition.
Heat treatment & final condition
The ordered annealed or solution-treated state is retained in the lot record; forming and machining do not replace the specified thermal condition.
Finished geometry
End lengths, runout and effective thread engagement are checked separately from overall length; tap ends are gauged to their own fit requirement.
Where 600 fits — and what matters
High-temp refinery & coker flanges
Inconel 600 Stud BoltsInconel 600 studs provide fixed mounting points on hot refinery accessory covers and selected flanges exposed to oxidizing or carburizing conditions. Nuts can be removed to open the connection without withdrawing body-mounted studs. Specify the required load at operating temperature: this solid-solution alloy is chosen for heat resistance, with strength assessed for the particular joint.
Connection requirements
- Flange thickness, gasket type, and required preload
- Stud diameter, overall length, and nut engagement at each end
- Temperature range, cycling duty, and heat-number certification
Heat shields & furnace linings
Inconel 600 Stud BoltsFor lining retainers and shield supports, 600 studs provide fixed attachment points through insulation or stand-offs. Oxidation resistance protects the exposed hot-side metal. Nuts on the accessible end allow retainers to be removed without withdrawing the entire stud from the furnace structure.
Connection requirements
- Panel and lining thickness, and required preload
- Stud diameter, overall length, and nut engagement at each end
- Temperature range, cycling duty, and heat-number certification
Recovery boiler & causticizing hardware
Inconel 600 Stud BoltsStuds on caustic-liquor covers can remain in the equipment while the nuts and cover are lifted off. Inconel 600 is useful where hot alkaline exposure reaches these fastening points. That combines a serviceable cover arrangement with a material selected for the local caustic environment.
Connection requirements
- Hardware joint thickness, gasket type, and required preload
- Stud diameter, overall length, and nut engagement at each end
- Hot caustic exposure, cycling duty, and heat-number certification
Same stud. Different material priorities.
Inconel 600 material dataInconel 601 Stud Bolts
Inconel 601 studs provide fixed, oxidation-resistant mounting points for furnace covers, lining retainers and hot-side supports. Nuts can be removed while the stud stays installed. Projection and stand-off length help place the accessible nut away from the hot attachment point.
Incoloy 800 Stud Bolts
Incoloy 800 studs provide fixed, heat-resistant mounting points for retort covers and furnace accessories. Nuts can be removed while the stud remains in place. The alloy suits selected oxidation- and carburization-exposed duties, with the required hot load distinguishing general 800 from creep-focused 800H.
Hastelloy C-276 Stud Bolts
Hastelloy C-276 studs suit repeatedly opened reactor, scrubber and acid-exchanger covers exposed to corrosive deposits or process leakage. The alloy protects the loaded stud surfaces in compatible mixed chemical media. Removable nuts provide access while body-mounted studs can remain installed.

Questions about 600 stud bolts & threaded rods
Does changing the stud alloy also change the nut selection?
The nut needs compatible internal threads, sufficient engaged height and a specified material condition. Select lubricant or surface treatment with the stud–nut pair, because assembly friction affects the preload obtained from tightening.
