Inconel 601 Socket Head Cap Screws
ISO 4762ASTM B166
Inconel 601 socket head cap screws pair a solid-solution nickel-chromium alloy with a compact, tapped assembly form for furnace fixtures and panels that cycle between heating and cooling. The alloy resists scaling and oxidation.

Heat Treatment
AnnealedAnnealing reduces work hardening and restores ductility for the specified supplied condition.
What we can make in Alloy 601
Partial thread
Use where a plain grip must span the clamped components. Match the under-head length and thread length so the screw tightens the stack before its thread runout reaches the tapped hole.
Full thread
Use for shorter component stacks and varied tapped-hole depths. The longer usable thread offers adjustment, while the screw end must clear the bottom of a blind hole.

Manufacturing route
CNC machining suits samples and small lots. Cold heading or hot forging is selected for volume production according to alloy formability, head section and size.
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
Head geometry, bearing face, shank and thread fit are checked after the final machining and thermal operations.
Where 601 fits — and what matters
Retort & muffle covers
Inconel 601 Socket Head Cap Screws601 socket screws suit recessed retort accessory covers exposed to heat and oxidation. Their drive can be reached between nearby fittings or close-fitting furnace components, allowing the accessory to be removed without dismantling surrounding hardware.
Connection requirements
- Tapped-hole size, thread form, and effective engagement depth
- Head diameter, head height, and socket depth for drive engagement
- Temperature range, cycling duty, and heat-number certification
Burner mounts & nozzles
Inconel 601 Socket Head Cap ScrewsInconel 601 socket screws secure burner mounting plates near hot combustion hardware. Its aluminium-bearing chemistry supports oxidation resistance at these exposed fastening points. The internal drive reaches recessed holes among fuel-air components, allowing the mounting plate to be serviced in a crowded assembly.
Connection requirements
- Tapped-hole size, thread form, and effective engagement depth
- Head diameter, head height, and counterbore clearance required
- Temperature range, vibration duty, and heat-number certification
Heat shields & furnace linings
Inconel 601 Socket Head Cap ScrewsSmall heat-shield retainers often need compact screw heads within a tight assembly envelope. Inconel 601 socket screws offer that form in an oxidation-resistant furnace alloy. The joint can use stand-offs or movement clearance for the shield, while the screw holds the retainer or bracket in place.
Connection requirements
- Tapped-hole size, thread form, and effective engagement depth
- Head diameter, head height, and socket depth for drive engagement
- Temperature range, cycling duty, and heat-number certification
Same socket head cap screw. Different material priorities.
Inconel 601 material dataInconel 600 Socket Head Cap Screws
Inconel 600 socket head cap screws secure small retort covers, shield retainers and furnace accessories. Heat and oxidation resistance complement the compact head form. Axial tool access is useful at counterbored mounts where nearby housings or brackets obstruct an external hex.
Incoloy 800H Socket Head Cap Screws
Recessed support blocks on hot piping or furnace equipment can keep a small screw under load throughout the operating run. Incoloy 800H socket screws combine a creep-focused material condition with axial tool access. They serve drawing-specific hot supports where long-duration load capacity matters more than a general heat-resistant alloy designation.
Nimonic 75 Socket Head Cap Screws
Nimonic 75 socket head cap screws fit small furnace retainers, burner accessories and fixture blocks with moderate loads. Scaling resistance supports the hot exposure. A recessed, axially reached head keeps the fastener within a compact mounting envelope.

Questions about 601 socket head cap screws
What changes when the screw is stronger than the housing?
The housing thread can strip before the screw reaches its tensile capacity. The engagement depth and housing material therefore belong in the joint assessment alongside the screw’s final strength condition.
