Titanium Grade 5 Hex socket countersunk screws
ISO 10642ASTM B348
Flush seating puts the load into the conical head of a Titanium Grade 5 countersunk screw. Higher strength than commercially pure titanium at low density is combined with a matching head angle and acceptance of the reduced head section.

AnnealedAnnealing reduces working stresses and restores ductility, with atmosphere and surface control limiting contamination during heating.
What we can make in Titanium Grade 5
Head angle & seating
90° metric and 82° inch heads need matching countersinks. Head diameter and recess depth control whether the screw sits flush.
Socket & overall length
Specify overall length including the head. Socket size and depth govern key engagement, especially in shallow head sections.
Reduced head loadability
ISO 10642 identifies reduced loadability from the countersunk head and socket geometry. For Inconel 718 or A-286, assess head capacity and seating contact alongside the specified material strength and assembly preload.

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 angle, socket depth and the head-to-shank transition are inspected with the thread; the reduced head section remains part of finished-part acceptance.
Where Titanium Grade 5 fits — and what matters
Industrial Machinery & Automation
Machine guards and instrument panelsTitanium Grade 5 hex socket countersunk screws secure machine guards and instrument panels with the head below or flush with the surface, leaving clearance for neighbouring moving parts or removable covers. Alignment, operating cycles and replacement access define the working interface.
Pumps, Valves & OEM
Actuator housings and removable equipment coversTitanium Grade 5 hex socket countersunk screws secure actuator housings and removable equipment covers with the head below or flush with the surface, leaving clearance for neighbouring moving parts or removable covers. Repeated maintenance makes fit, engagement and access part of the component specification.
Automotive & EV Manufacturing Equipment
Production-machine guards and sensor panelsTitanium Grade 5 hex socket countersunk screws secure production-machine guards and sensor panels with the head below or flush with the surface, leaving clearance for neighbouring moving parts or removable covers. Repeated tooling changes require consistent seating and repeatable assembly dimensions.
Same hex socket countersunk screw. Different material priorities.
Titanium Grade 5 material dataTitanium Grade 2
Low mass, corrosion resistance and commercially pure titanium formability.
- Connection priority
- Head-bearing stress in the reduced countersunk section
- 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 conical seat and recessed socket in the exposure description.
Inconel 718
Precipitation-hardened strength for compact, highly loaded connections.
- Connection priority
- Head-bearing stress in the reduced countersunk section
- 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 conical seat and recessed socket, the relevant metal temperature can differ from the process or furnace set point.

Questions about Titanium Grade 5 hex socket countersunk screws
Does a high-strength alloy remove countersunk-head loadability limits?
The conical head and socket still reduce the available section. Head-bearing stress, countersink contact and housing thread engagement need assessment alongside the final alloy strength.
