Traxxas Shoulder Screws 3x12mm Hex Drive for RC Shock Assembly Pack of 6 TRX3642X

Overview

The Traxxas Shoulder Screws 3x12mm (TRX3642X) are precision-engineered fasteners designed specifically for shock attachment on a wide range of Traxxas RC vehicles. This set of six shoulder screws with hex-drive heads provides the secure mounting solution you need to keep your suspension system firmly in place during intense bashing sessions and competitive racing. Whether you're running a high-performance brushless RC monster truck, a nimble short course truck, or a rally car, these replacement screws ensure reliable shock attachment and consistent suspension performance across countless drives.

Shoulder screws are critical components in any RC car suspension setup, as they bear the load of the entire shock assembly and absorb the forces generated during acceleration, braking, and cornering. The 3x12mm sizing is perfectly proportioned for Traxxas' ultra shock design, and the hex-drive head ensures you can apply precise torque without stripping or damaging the fastener. For RC enthusiasts in the UK looking for genuine Traxxas replacement parts, these shoulder screws represent an essential spare that should be in every basher's toolkit. Whether you're maintaining your fleet of RC vehicles or building up a new setup, having quality replacement shock screws on hand means less downtime and more track time.

Traxxas is recognised globally as the leading manufacturer of ready-to-run RC cars and trucks, and every component they produce—including these shoulder screws—meets the same exacting quality standards that their vehicles are famous for. When you choose genuine Traxxas parts for your RC car maintenance and repairs, you're choosing reliability, durability, and proven performance that keeps pace with your driving ambitions.

Key Features

• Set of Six Screws — This pack contains six shoulder screws, giving you a complete spare set for multiple shock assemblies or allowing you to maintain stock when replacements wear out during regular use and maintenance routines.
• 3x12mm Specifications — The 3mm diameter with 12mm length is precisely engineered to fit Traxxas ultra shock designs, ensuring perfect compatibility with the suspension geometry and load-bearing requirements of compatible vehicles.
• Hex-Drive Head Design — The hex socket drive head allows you to apply controlled, consistent torque using a hex wrench or driver bit, preventing the rounding and damage that can occur with inferior fastener designs and ensuring reliable fastening every time.
• Shock Attachment Purpose — These screws are specifically designed for shock mounting, meaning they're engineered to handle the vertical loads, lateral forces, and vibration that suspension components experience during off-road RC car driving.
• Genuine Traxxas Part — This is an official Traxxas component, manufactured to the same quality standards and specifications as the suspension systems found on new Traxxas vehicles, guaranteeing perfect fitment and long-term reliability.
• Black Colour Finish — The black finish provides a professional appearance and offers corrosion resistance to protect against dirt, moisture, and the elements encountered during regular RC car use on UK terrain.

Technical Performance

The Traxxas Shoulder Screws TRX3642X represent a thoughtfully engineered fastening solution that accounts for the demanding operational environment of modern RC vehicles. The 3x12mm shoulder screw design incorporates a precision hex-drive head that interfaces cleanly with standard hex sockets and drivers, allowing you to achieve the proper torque specification without risk of cam-out or fastener damage. The black colour finish provides visual continuity with Traxxas' suspension designs whilst offering enhanced corrosion resistance—an important consideration for UK-based RC enthusiasts who may encounter damp conditions or wet terrain during outdoor bashing sessions. These shoulder screws are engineered to maintain their integrity under the continuous vertical loading and lateral shock forces generated during acceleration, braking, and cornering manoeuvres. The material composition and manufacturing tolerances ensure consistent performance across multiple installation and removal cycles, meaning you can disassemble and adjust your suspension without fear of fastener degradation. When used with compatible Traxxas shock towers and mounting points, these screws provide secure, vibration-resistant attachment that keeps your suspension geometry stable and responsive through every jump, landing, and turn.
