Overview
The Traxxas Attachment Screws (3x12mm Shoulder Screws) TRX3642 are essential replacement parts for RC car enthusiasts and serious bashers alike. This pack of six precision-engineered shoulder screws is specifically designed as shock attachment screws, connecting your shock towers to the main chassis on compatible Traxxas vehicles. Whether you are running a 1/10 scale RC monster truck, exploring the world of RC car UK models, or maintaining your existing fleet of brushless RC vehicles, having quality replacement fasteners on hand is crucial for keeping your rig in top condition.
Shock attachment points are critical components in any RC car suspension system, as they bear significant loads during aggressive driving, jumps and high-impact landings. Over time, these screws can become stripped, bent or lost entirely, compromising your vehicle's handling and potentially causing damage to your shock towers. The TRX3642 offers an authentic Traxxas solution that meets original equipment manufacturer standards, ensuring perfect fitment and reliable performance on your ready to run RC truck or custom build.
These shoulder screws are the genuine article from Traxxas, the world-leading manufacturer of radio-controlled vehicles and parts. With a proven track record supplying OEM fasteners to countless RC enthusiasts across the UK and beyond, Traxxas parts represent quality, durability and peace of mind. Whether you are repairing battle-worn suspension components or simply maintaining preventative spares for your RC collection, the TRX3642 delivers dependable fastening performance.

Technical Performance
The TRX3642 shoulder screws represent precision engineering focused on the critical interface between your RC car's shock assembly and chassis structure. At M3 size with a 3x12mm shoulder specification, these fasteners are sized specifically for the mounting holes found on Traxxas shock towers and compatibility with the suspension geometry of supported vehicle models. The machine thread construction ensures smooth engagement with corresponding threaded holes, while the shoulder design prevents over-tightening and damage to delicate composite or aluminium chassis components. The Phillips-drive head offers practical usability in the field or workshop, allowing quick installation with minimal tool requirements. Build quality reflects Traxxas's commitment to reliability — the black finish resists oxidation and corrosion, critical for maintaining fastener integrity when your RC car is exposed to outdoor conditions, moisture from wet terrain, or storage in garage environments. These screws are engineered to withstand the vibration, impact loads and repeated stress cycles inherent in 1/10 scale monster trucks, buggies and other platform vehicles during aggressive driving, jumps and technical terrain navigation.

Frequently Asked Questions
- What are shock attachment screws and why do I need them for my RC car? — Shock attachment screws connect your suspension shock absorbers to the main chassis shock towers on your RC vehicle. They are critical fasteners that bear constant stress during driving, jumping and impacts. Over time they can become stripped, bent or lost, requiring replacement to maintain proper suspension geometry and handling characteristics on your RC truck or buggy.
- Are these screws compatible with my Traxxas RC vehicle? — The TRX3642 shoulder screws are confirmed compatible with multiple Traxxas models including the Stampede 4X4 HD VXL brushless electric monster truck (available in green, blue and orange variants) and the WideMaxx monster truck range (Rock N Roll, green and red versions). If you own a different Traxxas model, consult your vehicle manual or contact us to verify compatibility before ordering.
- What is a shoulder screw and how is it different from a regular machine screw? — A shoulder screw features a stepped design with a larger diameter cylindrical shaft (the shoulder) between the threaded portion and the head. This design prevents over-tightening and damage to mounting holes in delicate materials, and helps maintain proper spacing and alignment of suspension components — critical for suspension performance in RC vehicles.
- How often do shock attachment screws need replacement? — The frequency of replacement depends on how heavily you bash or race your RC car. Screws may become loose, stripped or bent during impacts and hard landings. Regular inspection of your shock towers during routine maintenance is recommended, and keeping spare fasteners on hand allows quick repairs to keep your vehicle in action.
- Can I use standard M3 screws instead of these Traxxas shoulder screws? — While standard M3 machine screws might physically fit, genuine Traxxas OEM shock attachment screws are engineered to exact specifications for proper fitment, load bearing and suspension alignment. Using non-standard fasteners risks misalignment, damage to shock towers and compromised handling, so genuine Traxxas TRX3642 screws are the recommended choice.
- What tools do I need to install these screws? — The Phillips-drive heads require only a Phillips-head screwdriver, available in most RC pit tool kits. No specialised tools or equipment is necessary, making installation quick and accessible whether you are performing roadside repairs during RC racing or comprehensive workshop maintenance.
