Overview
The HOBAO HYPER CNC ALUM. 3MM COUNTERSUNK WASHER (10) H36811 represents a premium fastening solution for RC enthusiasts who demand the highest quality components for their scale models. These professionally engineered aluminium washers are essential upgrades for any RC car UK builder looking to enhance reliability and performance. Whether you're setting up a ready to run RC model or customising your competition machine, these CNC-machined washers provide the precision engineering that separates amateur builds from professional-grade setups.
Designed specifically for the HOBAO Hyper series RC cars, these washers are particularly valued by builders working with 1/10 scale models who appreciate the importance of load distribution and fastener security. The countersunk design ensures flush mounting with servo horns and mounting plates, creating a clean aesthetic while maintaining structural integrity under the demanding conditions of RC racing, bashing, and trail running.
RC Model Shop stocks authentic HOBAO components because we understand that genuine OEM parts are crucial for optimal performance and longevity. These washers are manufactured to HOBAO's exacting standards using CNC machining processes that ensure consistency and reliability across every unit in the pack.
Key Features
- CNC Aluminium Construction — The washers are precision-machined from high-grade aluminium alloy, providing the perfect balance between lightweight design and exceptional durability that modern RC racing demands.
- 3mm Diameter Specification — The 3mm sizing is optimised for HOBAO servo mounting applications and fastening points throughout the Hyper platform, ensuring perfect fitment without modification.
- Countersunk Design — The countersunk profile allows fasteners to sit flush with mounting surfaces, creating a professional appearance whilst preventing snagging on moving parts and reducing aerodynamic disruption on high-speed models.
- Pack of 10 Units — This generous quantity provides sufficient washers for complete servo installation, shock tower mounting, and additional fastening points across your RC car, with spares for future maintenance or additional builds.
- Genuine HOBAO Component — As an original equipment manufacturer part, this washer is engineered to work seamlessly with HOBAO Hyper series vehicles, ensuring compatibility and performance that aftermarket alternatives cannot guarantee.
- Professional-Grade Engineering — The CNC machining process produces washers with precise tolerances, ensuring consistent performance and eliminating the dimensional variation common in budget fastening components.
Technical Performance
These CNC aluminium washers represent the engineering philosophy that HOBAO applies across the entire Hyper range of RC cars. The 3mm diameter is specifically calculated to work with the fastening systems used throughout HOBAO's 1/10 scale vehicles, particularly servo mounting horns and suspension mounting points. Aluminium was selected as the material because it provides exceptional strength-to-weight characteristics essential in modern RC racing, where every fraction of a gram impacts acceleration, handling and overall performance. The countersunk profile is particularly important in applications where fasteners need to sit flush with surfaces — this prevents the washers from catching during assembly, reduces interference with moving components like servo linkages, and contributes to the clean, professional appearance expected in competitive RC racing. The CNC machining process ensures that tolerances are held within tight specifications, meaning every washer in the pack will perform identically and seat properly regardless of which fastening point you're working with. For builders of brushless 1/10 scale RC buggies, crawlers, and racing models, the reliability of fastening hardware is non-negotiable, and these genuine HOBAO components deliver the consistency that competition demands.

Frequently Asked Questions
- What is a countersunk washer and why does my RC car need one? — A countersunk washer has a conical depression that allows the head of a fastener to sit flush with the mounting surface. In RC cars, this design prevents the washer from interfering with moving components like servo linkages and shock absorbers, whilst distributing load more effectively than flat washers. This is particularly important in precision-engineered vehicles like the HOBAO Hyper series where every millimetre matters.
- Are these washers compatible with other RC car brands? — Whilst these washers are specifically engineered for HOBAO Hyper series vehicles, the 3mm diameter makes them potentially suitable for other RC cars using similar fastening systems. However, for guaranteed compatibility and performance, we recommend using them with the HOBAO models they were designed for.
- Why buy genuine HOBAO washers instead of generic aftermarket alternatives? — Genuine OEM components like these HOBAO washers are manufactured to precise tolerances using CNC processes that ensure consistency across every unit. Aftermarket washers may have dimensional variations that compromise fit, increase fastener loosening, and potentially affect vehicle performance. For competitive RC racing and serious bashing, genuine components are worth the investment.
- How many washers do I need for my RC car? — The pack contains 10 washers, which is typically sufficient for a complete servo installation, shock tower mounting, and additional fastening points on a 1/10 scale RC car, with some spares for future maintenance. Check your build manual to confirm the exact number required for your specific model.
- Can I use these washers on brushless and nitro RC cars? — Yes, these washers are suitable for use with both brushless and nitro-powered RC vehicles within the HOBAO Hyper series. The material and design are compatible with the fastening requirements of both propulsion types.
