The 4x13mm dimensions make these pins suitable for several Traxxas models, and their popularity among the RC community speaks to their reliability and quality engineering.

• Hex Driver Type — The grub screw head design accepts standard hex drivers, making installation and removal straightforward using common RC tool kits and hobby screwdrivers that most RC enthusiasts already own and use regularly for vehicle maintenance.
• Black Finish — The hard-wearing black finish resists corrosion and wear, maintaining the professional appearance of your RC vehicle while providing durable protection against the elements encountered during outdoor RC car UK running sessions.
• 13mm Length — The 13mm length specification is precisely engineered for specific Traxxas mounting applications, ensuring correct engagement and preventing over-tightening or under-tightening that could compromise component security or cause damage to threaded holes.

Technical Performance

The TRX5189 screw pins represent precision fastening engineering specifically designed for the demanding requirements of RC vehicles. Built to M4 specification with machine thread design, these grub screws deliver consistent holding power essential for maintaining the integrity of critical components during high-speed running and the repeated impacts that characterise RC car UK hobby use. The 4x13mm dimensions are precisely calculated to provide optimal engagement in Traxxas-designed mounting points whilst avoiding over-tightening that could damage threaded holes or cause fastener failure. The factory-applied threadlock is a critical feature that sets these pins apart from standard fasteners; the threadlock prevents vibration-induced loosening that can occur during normal RC driving, ensuring that assembled components remain securely fastened throughout extended driving sessions. The hex driver type allows for straightforward installation using standard RC tools, making these pins accessible for drivers of all skill levels who need to perform routine maintenance, emergency repairs, or component replacement on their Traxxas vehicles. The black finish provides both aesthetic appeal and practical corrosion resistance, maintaining durability when vehicles are exposed to wet grass, dust, and environmental contaminants encountered during typical outdoor RC activity. These fasteners are engineered to work seamlessly with Traxxas suspension components, transmission assemblies, and structural elements that depend on reliable fastening to maintain vehicle performance and longevity.
