RC enthusiasts know that fasteners are often overlooked until you need them most.

This pack of eight screws gives you multiple replacements or the option to upgrade multiple vehicles at once.

Whether you're a seasoned RC racer, a weekend basher, or someone new to the world of RC cars and trucks, quality fasteners are the foundation of reliable performance. These button head hex screws are manufactured to tight tolerances and designed to withstand the stresses and vibrations that RC models experience during operation. The button head design provides a clean, low-profile appearance whilst the hex socket ensures secure engagement with standard hex key tools, making installation straightforward for builders of all skill levels.

Key Features

• M4 Thread Size — The M4 specification indicates these screws are compatible with standard M4 threaded holes found throughout FTX models and many other RC vehicles, ensuring broad compatibility across different platforms and configurations.
• 28mm Length — The 28mm length is engineered to provide sufficient engagement depth for secure fastening whilst remaining compact enough not to protrude excessively from assembly points, making these screws ideal for structural components on RC cars and crawlers.
• Button Head Design — The button head profile creates a clean, finished appearance on your RC model whilst providing better visibility of the screw head compared to standard cap screws, and the rounded top reduces snag points during assembly and disassembly.
• Hex Socket — The internal hex socket accepts standard hex key tools, providing precise torque application and reducing the risk of cam-out or stripping compared to Phillips or slot-head alternatives, which is essential when working with precision RC components.
• Pack of Eight — This eight-piece pack provides multiple replacement screws, allowing you to complete repairs on a single model or distribute fasteners across multiple RC vehicles in your collection, offering excellent value for active RC builders.
• FTX Brand Quality — As an FTX original part, these screws meet the manufacturer's exacting standards for fit, finish and performance, ensuring they integrate seamlessly with FTX models and deliver reliable long-term service through countless RC adventures.

Technical Performance

These button head hex screws are manufactured to ISO 4762 specifications, which defines the dimensional standards for socket head cap screws. The M4 x 28mm designation confirms the 4mm diameter thread with a 28mm overall length, providing the exact fastening solution needed for FTX models and compatible RC vehicles. The button head profile is slightly lower in height compared to traditional socket head cap screws, making these screws ideal for applications where clearance is limited or where a more refined aesthetic is desired. The hex socket design accommodates standard 3mm hex keys, which are ubiquitous in RC workshops and toolkits throughout the UK and beyond. Precision manufacturing ensures that thread pitch is consistent and that the hex socket walls are square and true, preventing stripping and ensuring reliable fastening through multiple assembly and disassembly cycles. The material composition and hardening process are optimised to provide strength sufficient for structural fastening on RC models whilst remaining lightweight, which is important in the weight-sensitive world of RC vehicles where every gram impacts performance, handling and battery runtime.
