These screws are perfect for securing suspension components, mounting brackets, servo mounts, and countless other assembly points throughout modern RC vehicles.

Key Features

• M3 x 16mm Specification — Precisely sized at M3 diameter with 16mm length, these screws fit standard RC suspension mounts, servo brackets, and structural components found on nearly every modern RC car, truck, and crawler sold in the UK market today.
• Hex Button Head Design — The distinctive hex socket button head provides superior grip for your hex key or Allen wrench, allowing you to apply consistent torque without stripping or slipping, which is essential when tightening suspension and mounting components.
• DIN 7380 Industrial Standard — These screws conform to DIN 7380, an internationally recognised specification that guarantees precise thread pitch, head dimensions, and material consistency, ensuring compatibility with genuine RC vehicle components and aftermarket parts.
• Hardened Steel Construction — Manufactured from quality steel with hardening treatment, these screws resist deformation under vibration and repetitive assembly cycles, which is critical in RC vehicles that experience high-frequency impacts and constant motion.
• Black Finish — The professional black finish not only looks great on your RC build but also provides a thin protective layer against corrosion and rust, extending the service life of the fasteners in outdoor racing and bashing conditions.
• Pack of 10 — Ten screws per pack provides excellent value, giving you spares for your current project plus backup fasteners for future builds, maintenance, or replacement of damaged hardware.
• Precision Threading — Each screw features consistently machined threads that engage cleanly and securely in threaded holes, preventing cross-threading and ensuring vibration-resistant fastening on demanding RC applications.

Technical Performance

These Corally steel screws represent professional-grade fastening hardware engineered for the demanding world of RC vehicles. The M3 x 16mm dimension is one of the most commonly specified sizes across modern RC car platforms—from high-performance racing buggies and stadium trucks to rock crawlers and short-course vehicles. The hex button head design is superior to standard Phillips or flathead screws because it distributes torque across a larger surface area, dramatically reducing the risk of stripped heads that can occur during assembly or maintenance of your RC car. The DIN 7380 specification guarantees that the thread pitch (typically 0.5mm for M3) matches precisely with threaded holes found on genuine RC components, ensuring secure, rattle-free connections even after thousands of kilometres of bashing or racing. The hardened steel material provides exceptional strength-to-weight ratio, crucial in RC applications where excess weight impacts acceleration, handling and battery runtime. These screws are designed to withstand the vibration cycles that naturally occur during high-speed driving, the repetitive assembly and disassembly that comes with regular maintenance, and the occasional overtightening that happens when builders use powered drivers. Whether you're a competitive racer tuning suspension geometry, a weekend basher maintaining your fleet, or a modeller building detailed scale vehicles, these screws deliver consistent, reliable performance that won't let you down mid-race or mid-run.

Frequently Asked Questions

• What are M3 x 16mm screws used for in RC vehicles? — These screws are used throughout RC cars for securing suspension components, mounting servo brackets, attaching body posts, securing differentials, and countless structural assembly points. The M3 size is standard across most 1/10 and smaller RC vehicles, making these essential spares for any RC enthusiast's toolbox.
• What is DIN 7380 and why does it matter? — DIN 7380 is an internationally recognised German industrial standard that specifies precise dimensions, thread pitch, and material requirements for hex button head screws. This means Corally screws are compatible with threaded holes designed for DIN 7380 fasteners, ensuring perfect fit and maximum security without risk of misalignment.
• Can these screws be used as replacement parts? — Yes, these M3 x 16mm hex button head screws are designed as genuine replacement fasteners for Corally RC vehicles and many other brands that use standard DIN 7380 specifications. Always verify the size requirement before ordering replacement fasteners for your specific vehicle.
• Why choose steel screws over plastic or nylon alternatives? — Steel screws provide superior strength, corrosion resistance, and holding power compared to plastic alternatives, which can strip under vibration and repeated assembly cycles. For demanding RC applications where reliability is essential, hardened steel is the professional choice.
• How many screws do I need? — This depends on your specific RC vehicle and application. A typical 1/10 scale RC buggy might use dozens of M3 screws throughout the suspension, chassis, and component mounting. Many builders keep multiple packs as emergency spares for races, maintenance sessions, and replacement of lost or damaged fasteners.
• Are these screws suitable for beginners? — Absolutely. These are standard fasteners used on beginner-friendly RTR (ready to run) RC cars, intermediate race kits, and advanced competition vehicles. Learning to use the correct size screws and proper tightening technique is fundamental to successful RC building at any skill level.
