Upgrade Fasteners with 3Racing Titanium Hardware

If you want to shave weight while keeping strength, the 3Racing TS-FS4120M titanium flat head hex socket screws are a straightforward choice. Intended for machine applications, these fasteners give hobbyists a precise, dependable way to secure parts without adding bulk.

Strong Yet Low Weight

Made from titanium, these screws resist wear and cut mass compared with steel alternatives. That balance of durability and lightness makes them useful for lightweight builds and sprint race setups.

Accurate Size and Retention

The 4-40 x 1/2 dimension gives a tight thread engagement to help prevent working loose under vibration. Proper fit preserves chassis alignment and minimises the need for frequent retightening.

Handy for Upgrades and Servicing

These screws work well for routine maintenance and selective component upgrades. Their compatibility across common RC parts makes them a practical addition to any tool box.

Will these fit standard 4-40 tapped holes?

Yes, the 3Racing TS-FS4120M are standard 4-40 x 1/2 screws and will fit typical 4-40 tapped holes used across many RC models.

Should I use threadlocker with titanium screws?

For high vibration areas consider a medium strength threadlocker. Use sparingly and follow the threadlocker instructions to avoid over application.

What driver do I need for the flat head hex socket?

A matching hex key or driver sized for the socket will give the best control. Avoid rounded drivers to protect the socket shape.
