Key Features

• M3*8 Specification — This metric-sized fastener measures 3mm in diameter with an 8mm length, making it a standard size for most 1:10 scale RC cars and compatible with numerous FMS models including the F100 platform. This size is commonly used for chassis mounting, suspension components and body work attachment, so having spares ensures you can complete any repair or upgrade.
• Cap Head Hex Design — The cap head hex socket configuration provides excellent grip for installation and removal using standard hex key tools, allowing you to work efficiently without damaging the fastener head. This design is more durable than phillips or slot head alternatives and provides better torque application for consistent fastening throughout your RC vehicle.
• Genuine FMS Manufacturing — As an official FMS part, this screw meets the exact specifications and quality standards required for FMS vehicles, ensuring perfect compatibility and reliability. Using genuine OEM fasteners rather than generic alternatives guarantees that your RC car will maintain its integrity and performance characteristics.
• Precision Engineering — FMS manufactures this fastener to tight tolerances, ensuring smooth installation into pre-drilled holes and consistent performance across multiple installations. The quality control standards applied to these fasteners mean you can rely on them for critical structural applications on your RC car.
• Essential Spare Part — Cap head hex screws are high-wear items in RC vehicles due to the constant vibration and stress experienced during driving and maintenance cycles. Having replacement screws available means you can keep your RC car running rather than being sidelined waiting for parts to arrive.

Technical Performance

The FMS CAP HEAD HEX SCREW M3*8 represents precision engineering at the component level. This fastener is manufactured to metric specifications with a 3mm shaft diameter and 8mm overall length, creating a compact yet robust fastening solution suitable for the tight tolerances found in modern 1:10 scale RC car construction. The cap head hex design features a smooth cylindrical cap with internal hex socket, allowing use with standard 2.0mm or 2.5mm hex keys depending on the specific configuration. The fastener head is precision-formed to ensure flush or slightly recessed mounting, which is critical in RC applications where aerodynamic efficiency and clean lines can impact performance. The material composition and hardness specifications ensure the screw can withstand repeated installation cycles, vibration from high-speed running, and the thermal stresses experienced during extended driving sessions. For UK RC car enthusiasts working with their 1:10 scale brushless RC vehicles or electric RC car setups, these fasteners are compatible with both plastic and aluminium chassis components commonly found in modern RC designs. The engineering behind this seemingly simple component reflects FMS Hobby's commitment to quality across their entire product range, from their complete ready to run RC cars down to individual replacement parts.

Frequently Asked Questions

• What is an M3*8 cap head hex screw used for in RC cars? — The M3*8 is a standard fastener size used throughout 1:10 scale RC cars for securing chassis components, suspension mounts, body panels and internal structural elements. The 3mm diameter provides excellent strength-to-weight ratio while the 8mm length allows secure fastening through multiple material layers without excessive protrusion. These screws are essential for maintaining structural integrity in your RC vehicle during high-speed running and rough terrain driving.
• Is this genuine FMS part compatible with my 1:10 RC car? — This is a genuine FMS manufactured part designed specifically for FMS vehicles, particularly the 1:10 F100 model and other compatible FMS chassis. While the M3*8 specification is a standard metric size used across many RC brands, genuine FMS fasteners are precision-manufactured to exact OEM specifications ensuring perfect fit and reliability. We recommend confirming compatibility with your specific model before ordering, though most modern 1:10 scale RC cars use this standard size.
• How many screws should I stock for my RC car? — Most 1:10 scale RC cars use dozens of cap head hex screws throughout their construction. We recommend stocking a variety of sizes including this M3*8, as fasteners frequently loosen or strip during normal use. Having a spare supply ensures you can maintain your RC car without downtime waiting for replacement parts to arrive from retailers.
• Can I use generic cap head screws instead of genuine FMS parts? — While generic metric screws may have similar external dimensions, genuine FMS parts are manufactured to exact tolerances and material specifications that ensure optimal performance and compatibility. Generic fasteners may have slightly different head shapes, thread pitches or material hardness that could cause fit issues or premature failure. For critical structural applications on your ready to run RC car, genuine OEM parts provide the reliability you need.
• What tools do I need to install this screw? — The cap head hex design requires a hex key (Allen key) for installation and removal. Most M3 cap head screws work with 2.0mm or 2.5mm hex keys, though you should verify the correct size for your application. A quality hex key set is an essential tool for any RC car UK enthusiast doing maintenance and repairs on their vehicles.
