Super Duplex S32760 Socket Head Cap Screws
ISO 4762ASTM A276
Super Duplex S32760 socket head cap screws fit compact seawater housings and process-equipment covers specified in this grade. The axial drive allows a narrow head envelope, while the final super duplex condition supports both strength and chloride-corrosion resistance.

What we can make in Super Duplex S32760
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; a volume heading or forging route must preserve duplex phase balance through forming and final thermal processing.
Heat treatment & final condition
Solution treatment and cooling control the duplex structure. Subsequent processing must preserve the ordered corrosion and mechanical condition.
Finished geometry
Head geometry, bearing face, shank and thread fit are checked after the final machining and thermal operations.
Where Super Duplex S32760 fits — and what matters
Submersible pump motor housings
Super Duplex S32760 Socket Head Cap ScrewsA submersible housing needs compact closure screws that stay within its outer profile. S32760 socket screws provide an axial drive and super duplex material for suitable seawater duty. The head counterbore and tapped-hole depth must match the screw so tightening loads the cover instead of bottoming the tip.
Connection requirements
- Housing pressure and screw load
- Counterbore and blind-hole dimensions
- Seawater and electrical-protection conditions
Energy recovery devices (ERDs)
Super Duplex S32760 Socket Head Cap ScrewsCompact energy recovery housings can leave little space between fasteners and fluid ports. S32760 socket screws allow tightening from above each head while keeping the chosen super duplex grade throughout the specified bolting. The available housing thread length must carry the load from the high-strength screw.
Connection requirements
- Port-to-head tool clearance
- Housing material and thread engagement
- S32760 finished condition
Seawater pumps
Super Duplex S32760 Socket Head Cap ScrewsS32760 socket screws secure recessed auxiliary covers on seawater pumps specified in this super duplex grade. Chloride resistance supports the wet exposure around the head and threads. The compact drive clears neighbouring brackets, with a supported counterbore and full-depth key access for servicing.
Connection requirements
- Counterbore support
- Drive access and cleaning
- Pump material specification
Same socket head cap screw. Different material priorities.
Super Duplex S32760 material dataSuper Duplex 2507 Socket Head Cap Screws
2507 socket screws are useful for compact saline-service housings that need higher strength and chloride resistance than common stainless fasteners. The cylindrical head fits a counterbore, and tightening is along the screw axis. The housing thread and head seat must be sized to carry the load available from the stronger screw.
254 SMO Socket Head Cap Screws
254 SMO socket screws suit compact wet-process covers where chloride exposure calls for more corrosion resistance than 316-type stainless. They provide access to recessed mounting points near pipework or adjacent castings. The head pocket's actual liquid exposure matters because deposits can remain after surrounding surfaces dry.
Inconel 625 Socket Head Cap Screws
Inconel 625 socket head cap screws fit compact seawater housings and wet-process covers where liquid can remain beneath the head or inside the drive. Chloride pitting and crevice-corrosion resistance supports these exposed fastening points. Axial access suits recessed mounts between adjacent fittings.

Questions about Super Duplex S32760 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.
