Titanium Grade 2 Tall flange nuts
ISO 4161ASTM B348
A tall Titanium Grade 2 flange nut extends the usable thread envelope and spreads the seating load. The grade brings low mass, corrosion resistance and commercially pure titanium formability, 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 2
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 2 fits — and what matters
Chemical Processing
Mixer drives and process-equipment bracketsTitanium Grade 2 tall flange nuts retain the threaded connections on mixer drives and process-equipment brackets, combining increased nut height with an integral bearing flange. Process liquid can remain at the contact after the exposed surface drains.
Pumps, Valves & OEM
Actuator mounts and pump baseplatesTitanium Grade 2 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.
Mining & Mineral Processing
Leach-equipment and dosing-skid supportsTitanium Grade 2 tall flange nuts retain the threaded connections on leach-equipment and dosing-skid supports, combining increased nut height with an integral bearing flange. Leach solution and deposits act on the installed part; corrosion duty is separate from abrasive wear.
Same tall flange nut. Different material priorities.
Titanium Grade 2 material dataHastelloy C-276
Resistance to chemically aggressive, mixed process streams.
- Connection priority
- Thread engagement over the tall body and flange bearing
- Process liquid and shutdown chemistry
- C-276 is selected for its nickel–chromium–molybdenum–tungsten chemistry. Residual product, cleaning liquid and oxidising contamination can expose a sheltered connection differently from the main flow. Include liquid retained at the extended internal thread and broad flange underside in the exposure description.
Inconel 625
Solid-solution strength and resistance to aggressive process liquids.
- Connection priority
- Thread engagement over the tall body and flange bearing
- 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 extended internal thread and broad flange underside in the exposure description.
Hastelloy C-22
Corrosion resistance across oxidising and reducing process exposures.
- Connection priority
- Thread engagement over the tall body and flange bearing
- Production and cleaning cycles
- C-22’s chromium-bearing chemistry is relevant when chemical exposure changes between operating and cleaning cycles. Include both liquids when comparing it with C-276 or a B-type nickel alloy. Include liquid retained at the extended internal thread and broad flange underside in the exposure description.

Questions about Titanium Grade 2 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.
