Titanium Grade 5 Tall flange nuts
ISO 4161ASTM B348
A tall Titanium Grade 5 flange nut extends the usable thread envelope and spreads the seating load. The grade brings higher strength than commercially pure titanium at low density, while engagement depth and flange contact determine the assembled fit.

Heat Treatment
AnnealedAnnealing reduces working stresses and restores ductility, with atmosphere and surface control limiting contamination during heating.
What we can make in Titanium Grade 5
Body height: regular / tall
- Regular height
- Fits compact equipment covers and mounting brackets where clearance above the nut is limited.
- Tall body
- Provides longer thread engagement on clamping studs in jigs, fixtures and machine-tool setups that are tightened and released repeatedly.
Bearing face: plain / serrated
- Plain face
- For painted covers and finished equipment faces where serration marks are unwanted.
- Serrated face
- For metal mounting brackets where teeth can bite directly into the seat to resist rotation.
All configurations shown are available on request.

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
Forming and thermal processing require contamination control. The final surface is cleaned before dimensional and material acceptance.
Finished geometry
Internal thread gauging, usable engagement and bearing-face alignment are checked after final processing.
Where Titanium Grade 5 fits — and what matters

Industrial Machinery & Automation
Machine frames and positioning fixturesTitanium Grade 5 tall flange nuts retain the threaded connections on machine frames and positioning fixtures, combining increased nut height with an integral bearing flange. Alignment, operating cycles and replacement access define the working interface.

Pumps, Valves & OEM
Actuator mounts and pump baseplatesTitanium Grade 5 tall flange nuts retain the threaded connections on actuator mounts and pump baseplates, combining increased nut height with an integral bearing flange. Repeated maintenance makes fit, engagement and access part of the component specification.

Automotive & EV Manufacturing Equipment
Assembly fixtures and test-rig framesTitanium Grade 5 tall flange nuts retain the threaded connections on assembly fixtures and test-rig frames, combining increased nut height with an integral bearing flange. Repeated tooling changes require consistent seating and repeatable assembly dimensions.
Same tall flange nut. Different material priorities.
Titanium Grade 5 material dataTitanium Grade 2
Low mass, corrosion resistance and commercially pure titanium formability.
- Connection priority
- Thread engagement over the tall body and flange bearing
- Commercially pure titanium
- Grade 2 favours corrosion resistance and forming characteristics over the higher strength of Grade 5. Mating-metal contact, surface condition and assembly friction remain part of the connection design. Include liquid retained at the extended internal thread and broad flange underside in the exposure description.
Inconel 718
Precipitation-hardened strength for compact, highly loaded connections.
- Connection priority
- Thread engagement over the tall body and flange bearing
- Strength after aging
- Machine-stock properties and final aged properties describe different states. The final heat-treatment lot and mechanical results establish the strength available in the installed part. At the extended internal thread and broad flange underside, the relevant metal temperature can differ from the process or furnace set point.

Questions about Titanium Grade 5 tall flange nuts
Does greater nut height automatically increase joint capacity?
Capacity depends on the engaged threads, nut condition and stud strength, as well as load distribution. Extra unengaged height does not add thread engagement and does not create prevailing torque.
