Titanium Grade 5 Serrated flange nuts
ISO 4161ASTM B348
Titanium Grade 5 serrated flange nuts engage the member directly through their toothed seat. Higher strength than commercially pure titanium at low density concerns the nut body; the substrate exposed by the serrations remains part of the same connection.

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 serrated flange nuts clamp machine frames and positioning fixtures through a serrated flange that engages the mounting face. The mating surface must accept the serration contact. Alignment, operating cycles and replacement access define the working interface.
Pumps, Valves & OEM
Actuator mounts and pump baseplatesTitanium Grade 5 serrated flange nuts clamp actuator mounts and pump baseplates through a serrated flange that engages the mounting face. The mating surface must accept the serration contact. Repeated maintenance makes fit, engagement and access part of the component specification.
Automotive & EV Manufacturing Equipment
Assembly fixtures and test-rig framesTitanium Grade 5 serrated flange nuts clamp assembly fixtures and test-rig frames through a serrated flange that engages the mounting face. The mating surface must accept the serration contact. Repeated tooling changes require consistent seating and repeatable assembly dimensions.
Same serrated flange nut. Different material priorities.
Titanium Grade 5 material dataTitanium Grade 2
Low mass, corrosion resistance and commercially pure titanium formability.
- Connection priority
- Bearing and tooth engagement against the member
- 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 serration tips and the covered flange seat in the exposure description.
Inconel 718
Precipitation-hardened strength for compact, highly loaded connections.
- Connection priority
- Bearing and tooth engagement against the member
- 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 serration tips and the covered flange seat, the relevant metal temperature can differ from the process or furnace set point.

Questions about Titanium Grade 5 serrated flange nuts
Will serrations preserve a coated bearing surface?
Serrations work by engaging the surface and can break its coating. Include the exposed substrate in the corrosion assessment; the nut’s own alloy cannot protect coating damage underneath it.
