Titanium Grade 5 Hex flange bolts
ISO 4162ASTM B348
An integral flange spreads the bearing load of a Titanium Grade 5 bolt. Higher strength than commercially pure titanium at low density addresses the service exposure; plain or serrated seating determines contact with the supported surface.

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
Integral flange
Use on mounting brackets and equipment covers to distribute head load over a wider seat and reduce loose parts during assembly. The flange needs a flat landing clear of nearby walls and radii.
Plain bearing face
Choose a plain underside for finished or coated seats where teeth would mark the surface. It also permits controlled sliding at the head-seat interface during tightening.
Flange vs loose washer
An integral flange speeds repeated assembly by keeping the bearing surface with the bolt. Retain a separate washer when the joint needs a replaceable wear face or a specifically hardened bearing layer.

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 hex flange bolts clamp machine frames and positioning fixtures through an integral flange that spreads head load over the mounting face. Alignment, operating cycles and replacement access define the working interface.
Pumps, Valves & OEM
Actuator mounts and pump baseplatesTitanium Grade 5 hex flange bolts clamp actuator mounts and pump baseplates through an integral flange that spreads head load over the mounting 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 hex flange bolts clamp assembly fixtures and test-rig frames through an integral flange that spreads head load over the mounting face. Repeated tooling changes require consistent seating and repeatable assembly dimensions.
Same hex flange bolt. Different material priorities.
Titanium Grade 5 material dataTitanium Grade 2
Low mass, corrosion resistance and commercially pure titanium formability.
- Connection priority
- Clamp load spread over the integral 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 broad flange underside and its edge against the member in the exposure description.
Inconel 718
Precipitation-hardened strength for compact, highly loaded connections.
- Connection priority
- Clamp load spread over the integral 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 broad flange underside and its edge against the member, the relevant metal temperature can differ from the process or furnace set point.

Questions about Titanium Grade 5 hex flange bolts
Can the flange replace a separate washer?
Only when its bearing footprint and the supported surface meet the assembly requirement. A serrated seat can damage a coating, while a thin or slotted member may need a different bearing arrangement.
