Titanium Grade 5 Long-shank flange bolts
ISO 4162ASTM B348
The long grip and integral bearing flange give Titanium Grade 5 bolts two distinct interfaces to control. Higher strength than commercially pure titanium at low density must be paired with the required shank length, flange footprint and final condition.

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
Flanged head
Use on deep mounting brackets and thick equipment stacks where a wide head seat distributes the clamp load. Check the flange diameter against casting recesses and nearby ribs before specifying a larger head.
Extended grip
The extended plain grip can span spacers and thick components while the thread engages beyond them. Match grip length to the assembled stack so the nut can reach its seat without stopping at the thread runout.

Manufacturing route
CNC machining provides the initial route for special heads and small lots. Formed production requires alloy-specific temperature and surface-contamination control.
Heat treatment & final condition
Forming and thermal processing require contamination control. The final surface is cleaned before dimensional and material acceptance.
Finished geometry
Head geometry, bearing face, shank and thread fit are checked after the final machining and thermal operations.
Where Titanium Grade 5 fits — and what matters
Industrial Machinery & Automation
Machine frames and positioning fixturesTitanium Grade 5 long-shank flange bolts span thick spacers or mounting sections in machine frames and positioning fixtures, combining an extended grip with a flange bearing face. Alignment, operating cycles and replacement access define the working interface.
Pumps, Valves & OEM
Actuator mounts and pump baseplatesTitanium Grade 5 long-shank flange bolts span thick spacers or mounting sections in actuator mounts and pump baseplates, combining an extended grip with a flange bearing face. Repeated maintenance makes fit, engagement and access part of the component specification.
Automotive & EV Manufacturing Equipment
Assembly fixtures and test-rig framesTitanium Grade 5 long-shank flange bolts span thick spacers or mounting sections in assembly fixtures and test-rig frames, combining an extended grip with a flange bearing face. Repeated tooling changes require consistent seating and repeatable assembly dimensions.
Same long-shank flange bolt. Different material priorities.
Titanium Grade 5 material dataTitanium Grade 2
Low mass, corrosion resistance and commercially pure titanium formability.
- Connection priority
- Grip tension and distributed bearing at the flange
- 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 grip and the covered surface under the flange in the exposure description.
Inconel 718
Precipitation-hardened strength for compact, highly loaded connections.
- Connection priority
- Grip tension and distributed bearing at the flange
- 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 grip and the covered surface under the flange, the relevant metal temperature can differ from the process or furnace set point.

Questions about Titanium Grade 5 long-shank flange bolts
Which dimensions keep the flange and long grip working together?
The flange seat fixes one end of the stack; plain grip and runout fix where the threaded section begins. Specify both against the actual stack thickness so the nut tightens on the parts rather than reaching the end of usable thread.
