17-4 PH Thin hex nuts
ISO 4035ASTM A564
Limited axial space is the reason to use a 17-4 PH thin nut. Its aging-controlled strength and hardness must be paired with the reduced thread engagement and the intended locking arrangement.

Heat Treatment
Solution treated, then aged to the specified H conditionCondition A is the solution-treated starting state; aging to H900, H1025 or H1150 sets the final strength–toughness balance.
What we can make in 17-4 PH
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
Solution treatment and the specified aging condition are recorded against the production lot; final dimensions are checked after thermal processing.
Finished geometry
Internal thread gauging, usable engagement and bearing-face alignment are checked after final processing.
Where 17-4 PH fits — and what matters
Industrial Machinery & Automation
Drive shafts, collars and guide pins17-4 PH thin hex nuts serve as jam or retaining nuts on drive shafts, collars and guide pins where axial space is limited. Their reduced thread engagement is part of the retention design. Alignment, operating cycles and replacement access define the working interface.
Automotive & EV Manufacturing Equipment
Fixture pins and positioning shafts17-4 PH thin hex nuts serve as jam or retaining nuts on fixture pins and positioning shafts where axial space is limited. Their reduced thread engagement is part of the retention design. Repeated tooling changes require consistent seating and repeatable assembly dimensions.
Pumps, Valves & OEM
Valve stems and pump-drive collars17-4 PH thin hex nuts serve as jam or retaining nuts on valve stems and pump-drive collars where axial space is limited. Their reduced thread engagement is part of the retention design. Repeated maintenance makes fit, engagement and access part of the component specification.
Same thin hex nut. Different material priorities.
17-4 PH material data316L
Molybdenum-bearing stainless performance in wet equipment.
- Connection priority
- Thread load in a reduced-height body
- Washdown and retained cleaner
- Cleaner concentration, rinse quality and deposits determine the exposure in covered joints. The low-carbon designation does not independently establish a fastener strength class. Include liquid retained at the short internal engagement and paired-nut faces in the exposure description.
Inconel 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.
Duplex 2205
Duplex strength and chloride-corrosion resistance.
- Connection priority
- Thread load in a reduced-height body
- S31803 or S32205
- The specified UNS fixes the chemistry. Solution treatment, section size and the ordered mechanical or corrosion tests establish the final duplex condition. Include liquid retained at the short internal engagement and paired-nut faces in the exposure description.

Questions about 17-4 PH 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.
