Titanium Hex Flange Head Bolts
Grade 5 titanium hex flange head bolts in M6 with an 11 mm integral flange and an 8 mm hexagon, in lengths from 10 mm to 90 mm.
Overview
What This Range Is
An external hexagon head with the flange formed as part of the head. The external drive lets the bolt be run with a socket or a spanner rather than a key, which matters where access is from the side or where the joint is made and broken often. The integral flange spreads the load and removes the separate washer.
Every size in the range is made in Grade 5 titanium. The head geometry and the drive size are listed for each size in the table below, taken from the product data for that size rather than from a general specification.
Problems This Range Solves
- Joints made and broken often where an internal drive would wear or pack with dirt
- Side access positions where a socket or spanner is the only practical tool
- Assemblies where the separate washer is a part number and a handling step worth removing
- Outdoor and wash down service where a zinc plated flange bolt would corrode at the flange

Material
Ti-6Al-4V Grade 5 Reference Data
Published values for the alloy and for ASTM B348. They describe the material, not a batch certificate.
| Alloy designation | Ti-6Al-4V, ASTM Grade 5 |
|---|---|
| UNS number | R56400 |
| Nominal composition | 6 percent aluminium, 4 percent vanadium, balance titanium |
| Alloy class | Alpha beta alloy |
| Density | 4.43 g/cm³ |
| Minimum tensile strength | 895 MPa / 130 ksi |
| Minimum yield strength | 828 MPa / 120 ksi |
| Minimum elongation | 10 percent |
| Modulus of elasticity | About 114 GPa |
| Magnetic response | Non magnetic |
| Melting range | About 1604 to 1660 °C |
Why It Matters For This Range
- Roughly 44 percent less mass than the same fastener in steel, which is the whole reason the range exists
- Yield strength high enough to replace a medium strength steel fastener rather than an aluminium one
- A stable oxide film that re-forms in air or water, so chloride service does not pit the fastener
- Non magnetic, so the fastener can sit next to sensors and imaging equipment

Use Guide
Fitting Titanium Fasteners
Use anti seize on the threads
Titanium galls readily against titanium and against stainless. A dry film or copper free anti seize on the thread and under the head keeps the torque to tension relationship predictable and lets the joint be broken later.
Torque to a titanium figure not a steel figure
Do not carry over a torque value from a steel or stainless fastener of the same size. The friction behaviour is different and the safe clamp load has to be set for the alloy and for the lubricant actually used.
Seat the drive fully before applying load
Push the Torx key or the socket right to the bottom of the recess before turning. A partly seated drive concentrates load on the top edge of the recess.
Watch galvanic pairings
Titanium is a noble metal. Where it is bolted directly to aluminium or magnesium in a wet environment, isolate the joint or accept that the lighter metal will carry the corrosion.
Keep the bearing face clean and flat
A wide flange or saucer face only works if it lands on a flat clean surface. Swarf or paint under the head shifts the clamp load off centre.
