Race-Focused Titanium Fasteners for Tuning

The 3Racing TS-FS4120M titanium flat head hex socket screws are specified for builders who tune setups for lap time and durability. Manufactured to machine tolerances, these screws give consistent clamp force and minimise unsprung mass where that matters.

Engineered for Strength and Mass Reduction

Titanium delivers a favourable strength to weight ratio compared with steel, allowing the reduction of component mass without sacrificing clamp integrity. That helps achieve sharper transient response in lightweight chassis configurations.

Consistent Thread Engagement and Retention

The 4-40 x 1/2 size is common in precision RC assemblies and provides predictable engagement depth to limit micro movement under sustained vibration. Use matched torque settings to maintain repeatable preload across fasteners.

Applicable in Setup and Service Work

These screws are suitable for targeted upgrades, servo mounts, linkages and other tuned locations where low mass and secure fastening improve overall performance. Keep spare drivers and check torque during setup changes.

Which areas of a race car benefit most from titanium screws?

Lightweight suspension links, servo mounts and body mounting points see the most benefit where weight reduction and reliable clamping improve dynamic response.

How should I set torque when fitting titanium fasteners?

Use conservative torque values and incremental tightening to achieve consistent preload. Refer to component manufacturer guidance and avoid over torqueing into softer materials.

Any compatibility notes for race prep?

Check mating materials for thread strength and consider threadlocker only where scheduled service intervals allow easy removal. Maintain an inventory of replacement screws for critical areas.
