Key Features
- M4 Thread Size — The M4 metric thread diameter ensures universal compatibility with a wide range of ARRMA components and provides optimal holding strength for medium-duty applications on RC vehicles, making these screws suitable for securing everything from servo mounts to suspension components.
- 25mm Length — The 25mm shaft length is carefully dimensioned to penetrate deeply into mounting surfaces while maintaining proper clearance, giving you the extended reach needed for certain assembly configurations without unnecessary extra material.
- Hex Socket Head Type — The grub screw design with hex socket (Allen key) drive ensures you can apply consistent torque without stripping the fastener head, making installation and removal straightforward for routine maintenance on your RC car UK setup.
- Machine Thread Construction — These are precision machine threads rather than wood screws, delivering consistent engagement and superior holding power in threaded holes, which is exactly what you need for reliable fastening on precision RC components.
- Pack of Four — Each package contains four individual set screws, giving you enough spares for multiple repairs or a complete replacement set for multiple mounting points, ensuring you're always prepared for maintenance without running short.
- Black Finish — The black coating provides both aesthetic consistency with ARRMA components and corrosion resistance, helping to protect the screw from oxidation and maintaining its appearance even after extended use in outdoor RC conditions.
- OEM Quality — As genuine ARRMA parts, these set screws meet the manufacturer's exacting standards for fit, finish and performance, guaranteeing they will work perfectly with your ARRMA vehicle without compatibility concerns.
Technical Performance
The ARRMA Set Screw M4x25mm represents precision engineering in fastener design. With an M4 metric thread diameter, these screws provide secure fastening for medium-load applications typical in RC vehicle assembly and maintenance. The 25mm length is engineered to deliver sufficient penetration into mounting surfaces whilst maintaining proper clearance margins, preventing over-penetration that could damage internal components. The hex socket head design enables consistent torque application during installation, which is critical for maintaining the structural integrity of your RC vehicle. Unlike standard fasteners, these machine-threaded set screws feature precision manufacturing that ensures repeatable engagement, meaning each screw will perform identically to the last, providing the reliability that competitive RC enthusiasts and casual basher drivers alike depend on. The black finish offers practical corrosion resistance, which is especially valuable if you operate your brushless RC vehicles in varying British weather conditions. These fasteners are specifically engineered for use on ARRMA RC models including the INFRACTION 4X4 1/8 3S BLX Resto-Mod Truck variants, demonstrating their suitability for modern brushless RC platforms that demand precision-engineered components.

Other RC brands may use different fastening standards, so always verify compatibility before substituting parts between manufacturers.
- How many screws do I get in a pack? — Each pack contains four individual set screws, providing enough for multiple repairs, complete replacement sets, or spare inventory for regular maintenance.
- What is a set screw and why would I need replacements? — Set screws are fasteners used to secure components in place on your RC vehicle, such as servo mounts, suspension brackets, and other critical assembly points.
