Alloy 926 Thin hex nuts
ISO 4035ASTM B649
Limited axial space is the reason to use a Alloy 926 thin nut. Its high-molybdenum, nitrogen-bearing resistance to chloride media must be paired with the reduced thread engagement and the intended locking arrangement.

What we can make in Alloy 926
Reduced-height body
Use in compact adjustment mechanisms and panel assemblies where axial clearance rules out a full-height nut. Check the required proof load against the reduced engagement rather than selecting on clearance alone.
Jam-nut arrangement
Use with a second nut to lock an adjustment on a threaded shaft or linkage. The specified nut order and tightening sequence are part of the locking arrangement, not simply two nuts tightened independently.

Manufacturing route
Small lots use machined blanks. Volume nut blanks use a forming route compatible with the alloy before machining the bore and tapping.
Heat treatment & final condition
The final annealed or specified strengthened condition is linked to the lot; an aging treatment is not assumed for a solid-solution alloy.
Finished geometry
Internal thread gauging, usable engagement and bearing-face alignment are checked after final processing.
Where 926 fits — and what matters
Offshore & Marine
Marine pump shafts and linkage pinsAlloy 926 thin hex nuts serve as jam or retaining nuts on marine pump shafts and linkage pins where axial space is limited. Their reduced thread engagement is part of the retention design. The assembled contact is exposed to saltwater, deposits and neighbouring metals.
Water Treatment & Desalination
Treatment-pump shafts and actuator partsAlloy 926 thin hex nuts serve as jam or retaining nuts on treatment-pump shafts and actuator parts where axial space is limited. Their reduced thread engagement is part of the retention design. The water stream, cleaning cycle and retained liquid define exposure at the installed part.
Oil & Gas
Valve actuator shafts and linkage pinsAlloy 926 thin hex nuts serve as jam or retaining nuts on valve actuator shafts and linkage pins where axial space is limited. Their reduced thread engagement is part of the retention design. Utility connections and pressure-boundary parts have separate acceptance requirements on the equipment drawing.
Same thin hex nut. Different material priorities.
Alloy 926 material dataInconel 625
Solid-solution strength and resistance to aggressive process liquids.
- Connection priority
- Thread load in a reduced-height body
- Annealed or solution-annealed 625
- The delivery condition affects strength and high-temperature response. Keep the specified condition with the component’s mechanical acceptance; 718-style aging is not the strengthening route for 625. Include liquid retained at the short internal engagement and paired-nut faces in the exposure description.
Super Duplex 2507
Super-duplex strength and resistance to chloride pitting.
- Connection priority
- Thread load in a reduced-height body
- Final duplex structure
- S32750 chemistry and final solution treatment belong together. Forming, section size and cooling affect the structure represented by the mechanical and corrosion records. Include liquid retained at the short internal engagement and paired-nut faces in the exposure description.
Monel K-500
Age-hardened strength in the nickel–copper alloy family.
- Connection priority
- Thread load in a reduced-height body
- Strength and hydrogen exposure
- K-500 gains strength through aging. Cathodic protection, hydrogen exposure and the ordered condition need joint consideration in highly loaded marine components. Include liquid retained at the short internal engagement and paired-nut faces in the exposure description.

Questions about 926 thin hex nuts
Can a thin nut replace a regular nut at the same load?
Reduced thread engagement changes stripping capacity. Check the reduced-height nut’s material condition and the intended jam-nut arrangement instead of transferring the regular nut’s load assumption.
