Description
The ZD Racing Hexagon Socket Headless Screw Set (Part No. 16066) is an essential hardware replacement package designed primarily for the ZD Racing MT-16 1/16 Brushless Monster Truck and BX-12 RC Truck families. These are commonly referred to as “grub screws” or “set screws” and are vital for securing rotating components to shafts within the vehicle’s drivetrain and suspension linkages.
Kit Contents & Specifications
- Part Number: ZD16066 (or labeled under the MT-16 parts tree).
- Screw Type: Headless set screws featuring an internal hexagon socket drive (requires a standard metric hex wrench/Allen key).
- Material: High-tensile hardened metal designed to resist stripping under high RPM vibration.
- Mixed Sizes Included: The standard packaging provides a mix of M3×8mm, M3×2.5mm, and M3×3mm headless screws.
Common RC Applications
Because these screws lack a traditional protruding head, they sit completely flush inside their destination components:
- M3×3mm / M3×2.5mm: Typically used to secure the metal motor pinion gear directly onto the motor’s flat-sided output shaft, or to lock down drive cups to the differential outdrives.
- M3×8mm: Commonly utilized in suspension hinge pins, sway bar mounts, or outer steering knuckle hubs to keep pivoting assemblies locked securely in place.
