Titanium Grade 2 Hex nuts
ISO 4032ASTM B348
Titanium Grade 2 nuts place low mass, corrosion resistance and commercially pure titanium formability in the internal thread and bearing face of the connection. Regular or heavy hex geometry, usable engagement and final condition must match the stud or bolt.

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
Regular hex
Use on equipment covers and mounting brackets with standard socket access. The compact wrenching envelope is useful where adjacent fasteners or housing walls restrict tool clearance.
Heavy hex
Use on flange-bolting sets and pressure-equipment joints calling for a heavy-hex pattern. The wider bearing footprint and larger wrench size require more seat area and socket clearance than a regular hex nut.
Thin hex
Use in restricted axial spaces or as part of a specified two-nut locking arrangement. Reduced thread engagement means a thin nut is not a direct load-capacity replacement for a full-height nut.

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
Chemical pump covers and reactor connectionsTitanium Grade 2 hex nuts complete the stud connections on chemical pump covers and reactor connections. The nut pattern provides the bearing area and thread engagement for the selected stud and tightening method. Process liquid can remain at the contact after the exposed surface drains.
Pumps, Valves & OEM
Pump casings and valve bonnetsTitanium Grade 2 hex nuts complete the stud connections on pump casings and valve bonnets. The nut pattern provides the bearing area and thread engagement for the selected stud and tightening method. Repeated maintenance makes fit, engagement and access part of the component specification.
Mining & Mineral Processing
Chemical-recovery pump and vessel coversTitanium Grade 2 hex nuts complete the stud connections on chemical-recovery pump and vessel covers. The nut pattern provides the bearing area and thread engagement for the selected stud and tightening method. Leach solution and deposits act on the installed part; corrosion duty is separate from abrasive wear.
Same hex nut. Different material priorities.
Titanium Grade 2 material dataHastelloy C-276
Resistance to chemically aggressive, mixed process streams.
- Connection priority
- Thread-stripping resistance and bearing pressure
- 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 internal threads and the nut-bearing face in the exposure description.
Inconel 625
Solid-solution strength and resistance to aggressive process liquids.
- Connection priority
- Thread-stripping resistance and bearing pressure
- 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 internal threads and the nut-bearing face in the exposure description.
Hastelloy C-22
Corrosion resistance across oxidising and reducing process exposures.
- Connection priority
- Thread-stripping resistance and bearing pressure
- 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 internal threads and the nut-bearing face in the exposure description.

Questions about Titanium Grade 2 hex nuts
Does a matching UNS make the stud and nut a matched set?
Matching chemistry addresses only one part of the order. Nut strength, effective engagement, internal thread fit and surface friction must also suit the stud and assembly tightening method.
