Inconel X-750 Socket Head Cap Screws
ISO 4762ASTM B637
Inconel X-750 socket head cap screws pair a precipitation-hardened nickel-chromium alloy with a compact, tapped assembly form for exhaust, shield, and burner components that cycle in heat and vibration. The alloy resists relaxation at elevated temperature.

Heat Treatment
Solution treated and agedSolution treatment prepares the alloy for controlled precipitation aging, which develops the strength of the ordered condition.
What we can make in Alloy X-750
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 batches. Volume heads are formed in a workable condition with the final aging route included in process planning.
Heat treatment & final condition
Solution treatment and the specified aging condition are recorded against the production lot; final dimensions are checked after thermal processing.
Finished geometry
Head geometry, bearing face, shank and thread fit are checked after the final machining and thermal operations.
Where X-750 fits — and what matters
Exhaust manifolds & expansion bellows
Inconel X-750 Socket Head Cap ScrewsX-750 socket screws suit loaded exhaust brackets reached through recessed mounting holes. They combine elevated-temperature mechanical properties with access between nearby pipes and supports. Specify the treatment condition around the screw's actual temperature and load duration.
Connection requirements
- Tapped-hole size, thread form, and effective engagement depth
- Head diameter, head height, and socket depth for drive engagement
- Temperature range, vibration duty, and heat-number certification
Heat shields & furnace linings
Inconel X-750 Socket Head Cap ScrewsSmall support blocks near furnace shields may need stronger hot fasteners than a simple heat-resistant retainer. X-750 socket screws can fill that role, using a service-appropriate heat treatment. The compact drive helps around crowded blocks and stand-offs without needing wrench clearance around the head.
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 X-750 Socket Head Cap ScrewsBurner mounts place small screws near hot hardware and limited tool paths. X-750 socket screws offer a precipitation-hardened option for loaded mounting points. Positioning the drive for maintenance access is important because the internal hex requires a clear approach along the screw axis.
Connection requirements
- Tapped-hole size, thread form, and effective engagement depth
- Head diameter, head height, and counterbore clearance required
- Temperature range, cycling duty, and heat-number certification
Same socket head cap screw. Different material priorities.
Inconel X-750 material dataInconel 718 Socket Head Cap Screws
Inconel 718 socket head cap screws put precipitation-hardened strength into highly loaded, counterbored connections on heated test fixtures and compact machinery mounts. The internal drive reaches the screw between adjacent components. They are especially relevant when the hole pattern limits screw diameter and the drawing calls for high strength at the actual operating temperature.
Nimonic 80A Socket Head Cap Screws
Nimonic 80A socket head cap screws secure compact burner brackets and furnace support blocks carrying significant hot loads. Precipitation-hardened strength is useful in these small fasteners. The internal drive provides access between adjacent hardware without clearance for an external wrench.
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.

Questions about X-750 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.
