Key Features

• M4 Thread Size — The M4 metric thread specification ensures perfect compatibility with your Hyper 7 kingpin assembly, providing the exact fit and securing force required for this critical suspension component without stripping or loosening under load.
• 12mm Length — The precisely engineered 12mm length provides adequate engagement with the kingpin assembly whilst maintaining the correct stack height and geometry for optimal suspension performance and handling characteristics.
• Socket Cap Head Design — The socket cap head style offers several distinct advantages over traditional slotted or Phillips head screws, including superior torque transmission, less likelihood of cam-out or stripping, and a cleaner, more professional appearance on your RC car.
• Hex Driver Type — The hex driver socket accepts standard hex key tools, allowing you to apply precise torque settings with greater control and consistency compared to traditional screw head styles, essential for maintaining suspension geometry.
• Machine Thread Construction — Machine-cut threading provides superior consistency and strength compared to rolled threads, ensuring reliable fastening that won't strip or fail during aggressive RC driving or competitive racing scenarios.
• Black Finish — The durable black coating provides excellent corrosion resistance and protects against rust and oxidation, particularly important if you frequently bash your RC car in wet conditions or muddy terrain typical of UK outdoor tracks.

Frequently Asked Questions

• Are these screws compatible with my Hyper 7 RC car? — Yes, these Fastrax M4 X 12 Socket Cap Head Screws are specifically engineered for Hyper 7 kingpin assemblies, making them direct replacement components for this popular RC platform. The M4 x 12 specification ensures perfect fitment without modification.
• What makes socket cap head screws better than regular screws for RC cars? — Socket cap head screws offer superior advantages for RC applications including better torque transmission through the hex socket, greater resistance to stripping compared to Phillips or slot-head alternatives, and the ability to achieve precise torque settings with standard hex key tools, all critical for maintaining suspension geometry on your RC car UK.
• How often should I replace these screws on my RC car? — Replacement frequency depends on your driving intensity and conditions. Casual weekend bashers might replace kingpin screws annually, whilst competitive racers or drivers in harsh conditions may replace them more frequently. If you notice any loosening, stripping, or corrosion, replace immediately to maintain suspension performance.
• Why is the black finish important? — The black finish provides genuine corrosion and rust protection, which is particularly important for UK RC enthusiasts who may encounter muddy or wet conditions during outdoor bashing sessions. Without proper coating, bare metal screws can oxidise and seize, making them difficult to remove for future maintenance.
• What is the difference between these and cheaper fasteners? — Genuine Fastrax screws feature machine-cut threads that deliver superior consistency and strength compared to budget alternatives with rolled threads. The precision manufacturing ensures reliable fastening without stripping, and the quality finish resists corrosion better, making them a worthwhile investment for anyone serious about maintaining their RC car properly.
• Do I need special tools to install these screws? — You'll need a standard metric hex key (Allen key) in the appropriate size to drive these socket cap head screws. The hex socket design makes installation straightforward and allows you to apply consistent, repeatable torque to maintain proper suspension geometry.
