Overview
The Losi Driveshaft Screw Pin M5x16mm Steel (10): SBR/SRR is an essential replacement and upgrade component for serious RC enthusiasts who operate Losi vehicles, particularly the Super Baja Rey 2.0 series. These precision-engineered fasteners are designed to secure driveshaft components with absolute reliability, ensuring consistent power delivery and drivetrain integrity during intense RC driving sessions. Whether you're a competitive racer, a weekend basher tackling challenging terrain, or an RC car UK hobbyist who demands genuine OEM parts, this pack of ten driveshaft screw pins represents excellent value and peace of mind for your brushless RC setup.
Driveshaft connections are critical to RC vehicle performance, and using quality fasteners ensures your Losi 1/6 scale truck maintains optimal alignment and power transmission. These M5x16mm machine thread grub screws with hex driver heads are manufactured to Losi's exacting standards, providing the durability and precision fit that ready to run RC models require. Having spare fasteners on hand is essential maintenance practice for any serious RC enthusiast, as driveshaft connections experience constant stress during acceleration, braking, and cornering. This pack gives you ten replacement pins, meaning you'll have comprehensive coverage for repairs, maintenance, and future upgrades.
The steel construction ensures these fasteners provide reliable clamping force without stripping, even under the demanding conditions of 4WD brushless RC vehicles. For owners of the Losi Super Baja Rey SBR 2.0 or similar Losi desert trucks, maintaining proper fastener quality is fundamental to preventing drivetrain failures and enjoying uninterrupted RC driving pleasure.
Key Features
- M5x16mm Machine Thread Specification — These fasteners are precision-sized to M5 diameter with a 16mm length, engineered specifically for Losi driveshaft applications where exact fitment is non-negotiable for proper component alignment and torque transmission.
- Steel Construction — The steel material provides superior strength and resistance to stripping compared to cheaper alternatives, ensuring these fasteners maintain clamping force through hundreds of charge cycles and intense driving sessions.
- Hex Grub Screw Design — The grub screw head type features a hex socket driver, allowing precise tightening with standard hex tools and ensuring consistent fastening force without risk of head damage or slipping.
- Black Finish — The black coating provides corrosion resistance and durability, particularly important for RC vehicles that may encounter dust, moisture, or salt conditions during outdoor operation.
- Pack of Ten — This economical pack includes ten fasteners, providing comprehensive spare coverage for driveshaft maintenance, component replacement, and future upgrades without requiring frequent reordering.
- Genuine Losi OEM Part — These are authentic Losi factory components, ensuring perfect fitment and compatibility with genuine Losi driveshaft components and maintaining your vehicle's reliability and performance characteristics.
- Super Baja Rey SBR 2.0 Compatibility — These fasteners are specifically designed for the Losi 1/6 Super Baja Rey SBR 2.0 4WD Brushless Desert Truck in both Blue and Yellow variants, as well as other Losi SRR models in the range.
Technical Performance
The M5x16mm steel driveshaft screw pins represent essential engineering for high-performance RC vehicles. In the context of brushless 4WD RC desert trucks like the Super Baja Rey 2.0, driveshaft fasteners experience constant cyclic loading from motor torque transmission, suspension articulation, and high-speed running. The M5 diameter provides substantial tensile strength whilst remaining appropriately sized for Losi's precision chassis design, whilst the 16mm length ensures adequate engagement depth in driveshaft components. The machine thread specification allows these fasteners to seat properly in tapped holes without requiring nuts, simplifying maintenance and reducing overall assembly complexity. Steel construction provides hardness values that resist the deformation and thread stripping that can occur with inferior fastening solutions, particularly important for RC vehicles operating at sustained high rpm and under load. The hex grub screw head type is superior to slotted designs as it distributes driver force more evenly across the head geometry, reducing the risk of driver camming out and damaging the fastener head. For 1/6 scale brushless RC vehicles generating substantial torque output, having reliable fasteners is absolutely fundamental to drivetrain longevity and performance consistency. These genuine Losi fasteners are manufactured to exacting tolerances that ensure compatibility with other Losi components and maintain the precision engineering that makes Losi vehicles competitive performers in both racing and recreational RC applications.

Frequently Asked Questions
- Are these driveshaft screw pins compatible with my Losi RC vehicle? — These M5x16mm fasteners are specifically designed for the Losi Super Baja Rey SBR 2.0 4WD Brushless Desert Truck in both Blue and Yellow versions, as well as other Losi SRR model variants. Consult your vehicle's parts diagram or contact our RC Model Shop team to confirm compatibility with other Losi models, as different scales and designs may require different fastener specifications.
- Why do I need replacement driveshaft screw pins for my RC car? — Driveshaft fasteners experience constant stress from motor torque, acceleration forces, and suspension articulation during RC operation. Over time or through intensive driving, these fasteners can loosen, strip, or wear, compromising drivetrain connection integrity and potentially causing power loss or component separation. Maintaining spare fasteners ensures you can quickly perform maintenance and repairs without interrupting your driving schedule.
- What tools do I need to install these fasteners? — The hex grub screw design requires only a standard hex Allen key or driver in the appropriate M5 size. Most RC enthusiasts have hex key sets as part of their RC toolkit, making these fasteners straightforward to install and adjust during maintenance sessions.
- How many driveshaft connection points do these fasteners cover? — This pack of ten fasteners provides multiple coverage options. The exact number of driveshaft connections on your vehicle depends on your specific Losi model and configuration, but having ten spare pins ensures comprehensive coverage for maintenance, replacement, and future upgrades without requiring immediate reordering.
- Are these genuine Losi fasteners or aftermarket components? — These are authentic Losi OEM factory components, meaning they are manufactured to Losi's exact specifications and quality standards. Using genuine fasteners ensures perfect fitment, compatibility with other Losi parts, and maintains the engineering integrity of your vehicle.
- What is the difference between machine thread and other fastener types? — Machine thread fasteners like these are designed to install into pre-tapped holes, unlike wood screws which cut their own threads. This design provides superior accuracy, repeatability, and consistency in fastening force, essential for precision RC vehicle engineering where exact component alignment is critical to performance.
