Technical Performance
The Futaba Servo Horn Lock Screw M3 x 8 represents precision engineering applied to a small but critically important component in radio control systems. The M3 metric thread specification provides excellent compatibility across Futaba's comprehensive metal gear servo lineup, which are renowned for their robust construction and powerful torque output. The lock screw design incorporates features to resist vibration-induced loosening, a common issue in high-vibration RC applications where servos experience constant movement and repositioning. Whether you're operating a ready to run RC car, a competition-grade RC buggy, or a custom-built RC rock crawler, the servo fastening system must remain completely secure at all times. These lock screws are manufactured from quality materials that resist corrosion and wear, ensuring they maintain their clamping force even after repeated installation and removal cycles. The 8mm length is specifically optimised to engage properly with Futaba servo horn mounting points without bottoming out or stripping the internal threads, a critical consideration for maintaining servo reliability across multiple seasons of RC use.

Frequently Asked Questions
- What size servos do these lock screws fit? — These M3 x 8mm lock screws are specifically designed for Futaba metal gear servos that accept M3 fasteners. If you're unsure whether your servo is compatible, check your servo manual or contact the RC Model Shop team for advice on servo compatibility and recommended spare parts.
- Why use lock screws instead of standard servo horn screws? — Lock screws feature a design that resists vibration-induced loosening, which is essential in RC applications where constant servo movement and vehicle vibration can cause standard screws to gradually work loose over time. This can result in servo horn movement and loss of control precision, making lock screws the safer and more reliable choice for metal gear servos.
- How many screws will I need? — Each servo horn typically requires one lock screw to secure it firmly to the servo output shaft. This 10-pack is ideal for maintaining multiple RC vehicles or keeping spares on hand for repairs and replacements over an extended period.
- Are these genuine Futaba parts? — Yes, absolutely. As an authorised Futaba retailer in the UK, RC Model Shop supplies only authentic Futaba replacement parts manufactured to original specifications. This guarantees compatibility, quality, and long-term reliability.
- Can I use these with plastic gear servos? — These lock screws are specifically engineered for metal gear servos. While they may physically fit some plastic gear servos, they are optimised for the heavier-duty requirements of metal gear servo applications, and Futaba recommends checking your specific servo specifications before use.
- How do I install these lock screws? — Installation is straightforward: align your servo horn with the servo output shaft, insert the lock screw through the horn into the threaded hole on the servo, and tighten firmly using an appropriate hex key or screwdriver. Ensure the screw is tight enough to prevent movement but not so tight that you strip the threads.
