Overview

The HoBao Head Cap Screws M3.5x14mm (4) H21003 are essential replacement fasteners designed specifically for HoBao Hyper 7 TQ2 RTR buggies and compatible models. Whether you're a dedicated RC enthusiast in the UK maintaining your competition-grade nitro buggy or a weekend basher looking to keep your ready to run RC car in peak condition, these precision-engineered screws are indispensable spare parts for any serious RC hobbyist.

HoBao is a recognised manufacturer of high-performance RC buggies and components, and these head cap screws represent the quality and reliability you can expect from genuine OEM parts. As a replacement component, these screws are perfect for restoring damaged fasteners, rebuilding engine assemblies, or maintaining spare parts for competitive RC racing. With an RRP of £1.99, these affordable spares represent excellent value for money and should be part of every RC car owner's workshop inventory.

RC car maintenance is crucial for consistent performance and longevity, and having the correct replacement parts on hand ensures your buggy is always race-ready. These genuine HoBao head cap screws maintain the structural integrity of your RC vehicle and ensure proper assembly of critical engine and chassis components.

Key Features

  • Genuine OEM Replacement Parts — These are authentic HoBao-manufactured fasteners designed to exact specifications for perfect fit and compatibility with HoBao Hyper 7 TQ2 RTR buggies, ensuring you're using the correct parts that match factory standards and maintain your vehicle's performance.
  • M3.5x14mm Specification — The precise metric dimensions ensure these screws fit perfectly into their intended mounting points without stripping, cross-threading or requiring modification, which is essential for maintaining structural integrity in high-vibration RC applications.
  • Pack of Four — You receive four individual head cap screws in each pack, providing enough spares to replace multiple damaged fasteners or to keep as backup components for your RC maintenance kit.
  • Compatible with Multiple HoBao Models — These screws work with the HBM7-TQC28DG, HBM7-TQC21DG, and HBM7-TQC28BU variants of the HoBao Hyper 7 TQ2 RTR buggy, making them versatile spares if you own any of these popular ready to run RC vehicles.
  • Affordable Spare Parts Solution — At just £1.89, these replacement screws represent exceptional value and are far more economical than replacing entire assemblies when fasteners become damaged or lost.

Technical Performance

HoBao head cap screws are manufactured to precise metric specifications that ensure compatibility with the threaded mounting points found throughout HoBao Hyper 7 TQ2 RTR buggy assemblies. The M3.5x14mm dimensions provide optimal grip length and diameter for securing critical components without over-tightening or creating stress concentrations in the surrounding material. Head cap screws, also known as socket head cap screws, feature a hexagonal recess that accommodates standard Allen keys or hex drivers, allowing controlled application of torque without slippage or damage to the screw head. The design is particularly important in RC applications where vibration from nitro engines and high-speed impacts can gradually loosen fasteners. Quality fasteners like these HoBao originals resist vibration loosening better than inferior replacements and maintain their dimensional accuracy throughout extended use. Whether you're performing routine maintenance on your ready to run RC buggy or conducting a complete engine rebuild after a season of competitive racing, genuine OEM fasteners ensure your vehicle maintains factory specifications and performs reliably. The precision engineering of these screws means they thread smoothly into prepared holes without requiring excessive force, which could damage the surrounding material or the fastener itself.

For orders under £120, we can still deliver to Northern Ireland and the outlying isles, as long as the item can be sent by Royal Mail, weighs less than 30kg, and fits within 61cm × 46cm × 46cm. Some highland and remote areas may carry an extra delivery charge as couriers often apply surcharges in these locations. If you live in one of these areas, feel free to contact us before ordering so we can confirm the delivery options and costs for you.
  • Most of our products include delivery in the price. If your order is under £90, a small delivery fee will apply but do not worry this will always be clearly shown at checkout before you complete your purchase.

Orders are dispatched Monday to Friday only. Some items may take a little longer and if that is the case we will always show the expected delivery time on the product page.
  • If your order includes items with different dispatch times we will normally wait and send everything together once all items are in stock. If one of the items is going to take a while we will give you the choice either wait for everything to arrive or let us send the available items now and deliver the rest later. It is up to you.
  • We use trusted delivery partners to make sure your order gets to you safely and on time. We use DPD for next working day deliveries and Royal Mail for the 2 day option.
  • As soon as your order is on its way we will send you a tracking number by email. If you provide your mobile number at checkout we will also send delivery updates straight to your phone so you can keep an eye on progress.
