Team Corally has built a reputation for manufacturing high-quality RC spare parts and upgrades, and these hex flat head screws exemplify that commitment to excellence.

For anyone running an RC car UK setup, having quality fasteners on hand is crucial. These M4 x 12mm hex flat head screws are the kind of component that makes the difference between a secure, reliable build and one that fails mid-run. The pack of 10 screws ensures you have spares for future repairs, upgrades, or multiple projects. RC hobbyists, whether they're bashers enjoying weekend fun or competitive racers, understand that premium fasteners prevent costly damage to their RC vehicles.

These screws are manufactured to DIN 7991 industrial standards, which means they meet strict European manufacturing specifications for consistency, strength and reliability. The black finish provides both aesthetic appeal and corrosion resistance, making these screws suitable for various RC applications including buggies, trucks, and crawler builds. When you invest in quality fasteners like these, you're investing in the longevity and performance of your RC car UK setup.

Key Features

• M4 x 12mm Specification — The M4 metric diameter and 12mm length make these screws perfectly suited for securing components on mid-sized RC cars and buggies where a secure, low-profile fastening solution is essential. This size is ideal for attaching servo mounts, electronics trays, and suspension components.
• Hex Flat Head Design — The hex socket flat head configuration provides excellent tool engagement and prevents cam-out, ensuring you can tighten and loosen these screws repeatedly without stripping the head. The flat head design sits flush with mounting surfaces, creating a clean, professional appearance on your RC vehicle.
• Steel Construction — Unlike plastic or lower-grade fasteners, these premium steel screws offer superior strength and durability, resisting shearing and stripping even under the demanding conditions of high-speed RC driving, jumps, and rough terrain bashings.
• DIN 7991 Compliance — These screws are manufactured to DIN 7991 industrial standards, which is the European specification for socket head cap screws. This ensures consistent quality, precise threading, and reliable performance across every screw in the pack.
• Black Finish — The black coating provides corrosion resistance and a professional appearance, protecting the steel from rust and weathering whilst maintaining the aesthetic integrity of your RC car project.
• Pack of 10 — This generous pack size means you'll have spare fasteners for multiple installations, repairs, or future projects, ensuring you're never caught short when you need to maintain or upgrade your RC vehicle.

Technical Performance

These Team Corally M4 x 12mm hex flat head steel screws represent a significant upgrade opportunity for RC car enthusiasts across the UK seeking to improve their vehicle's reliability and performance. The M4 metric specification provides the ideal balance of clamping force and component protection for most mid-sized RC vehicles, from electric buggies to scale crawlers. The 12mm length is precisely engineered to allow proper engagement with threaded inserts and mounting bosses without bottoming out or creating excess pressure. Steel construction delivers superior tensile strength compared to nylon or composite fasteners, which is critical when dealing with vibration from high-speed runs, suspension articulation during aggressive driving, or the constant micro-movements that characterise RC car operation. The DIN 7991 industrial standard compliance guarantees that each screw in the pack meets European manufacturing specifications for dimensional accuracy, material grade, and surface finish. The hex flat head design is particularly valuable because it maximises contact area with your hex key or Allen key, dramatically reducing the risk of head stripping which can render fasteners unusable. The black finish isn't merely cosmetic — it provides a protective oxide layer that resists corrosion, extends the lifespan of your fasteners, and maintains their appearance through multiple seasons of use. For RC car UK builders and maintainers, having quality steel fasteners in your spares box is non-negotiable.

Frequently Asked Questions

• Are these screws suitable for all RC car types? — The M4 x 12mm size makes these screws ideal for most mid-sized RC vehicles including buggies, trucks, and crawlers. However, larger 1/5 scale vehicles may require larger M5 screws, whilst smaller 1/16 scale cars may need smaller M3 fasteners. Always check your specific RC car manual or parts diagram to confirm compatibility.
• What is the advantage of steel fasteners over plastic or nylon alternatives? — Steel screws offer significantly superior strength, durability and reliability. Plastic fasteners can strip, bend or break under vibration and sustained clamping loads, whereas steel maintains its integrity through countless assembly and disassembly cycles. For serious RC car enthusiasts, steel is the only acceptable choice for critical fastening applications.
• Can I use these screws for repairs as well as new builds? — Absolutely. These screws are perfect both for building RC cars from scratch and for repairing or upgrading existing vehicles. Having a spare pack means you can replace damaged or lost fasteners quickly, keeping your RC experience uninterrupted.
• Why is the hex flat head design important for RC cars? — The hex socket flat head provides excellent engagement with your hex key, preventing the rounding out that commonly occurs with Phillips or slot-head fasteners. This is crucial for RC work where you might need to remove and reinstall fasteners many times throughout the life of your vehicle.
• Are these fasteners corrosion resistant? — Yes, the black finish provides corrosion resistance, protecting the steel from rust and oxidation. This is particularly important if you use your RC car in wet conditions or live in a coastal area where salt air can accelerate corrosion.
• What tools do I need to use these screws? — You'll need a 3mm hex key or Allen key to drive these M4 fasteners. Most RC builders have multiple sizes in their toolbox, so this is unlikely to be an issue.
