Motorcycle Sprocket Bolts BOLT Hex Kit 7pcs Class 10.9 Zinc Plated

Description

Product Overview

Introducing the BOLT 7‑piece alloy steel sprocket bolt kit, engineered for the demanding environment of off‑road motorcycling. Each bolt is forged from high‑grade alloy steel and finished in a durable silver zinc plating, providing a class 10.9 strength rating that exceeds typical aftermarket fasteners. The fully threaded M8 hex design ensures precise alignment with sprocket holes, while the 654 MPa shear capacity offers peace of mind under extreme torque and vibration. This combination of material quality and engineering precision creates a fastener that performs reliably in the most aggressive riding conditions, from desert dunes to forest trails.

The kit includes six bolts, each paired with a Fuji metal‑locking nut that features a proprietary lock‑wire design. This combination creates a double‑lock system: the nut’s metal‑locking feature resists loosening, and the pre‑applied thread‑lock patch on each bolt cures anaerobically when tightened, forming a chemical bond that further secures the joint. Together they deliver a maintenance‑free solution that stands up to the rigors of motocross, enduro, and trail riding. The nuts are engineered to match the bolt thread profile exactly, eliminating any play that could lead to chain misalignment or premature wear.

All components are sized for a standard 8 mm bolt diameter and a 10 mm inside thread, matching the specifications of most Japanese and European full‑size off‑road motorcycles. The kit also supplies matching washers that distribute load evenly across the mounting surface, reducing the risk of bolt head deformation and ensuring a flush, professional finish. The washers are made from the same alloy steel, providing consistent strength and corrosion resistance throughout the assembly.

To simplify installation, the package provides an 8 mm socket insert that fits standard socket wrenches, eliminating the need for specialty tools. The socket’s precision‑machined interior guarantees a snug fit, allowing the user to apply the correct torque without stripping the bolt head. This design consideration reflects BOLT’s commitment to user‑friendly hardware that saves time on the shop floor. The insert also features a low‑profile head that clears surrounding components, preventing interference during tightening.

Beyond the mechanical advantages, the kit’s silver exterior finish not only resists corrosion from road salt and moisture but also adds a clean aesthetic that complements the sleek lines of modern sport and adventure motorcycles. The alloy steel core maintains structural integrity even after repeated removal and re‑installation, making the kit a long‑term investment for riders who demand reliability and performance. Each bolt is inspected for dimensional accuracy and surface integrity before packaging, ensuring that every piece meets BOLT’s exacting quality standards.

Usage

The BOLT sprocket bolt kit is ideal for riders who regularly replace or upgrade their sprockets to fine‑tune power delivery. Whether you are preparing for a competitive off‑road event or simply seeking smoother acceleration on weekend trail rides, these bolts provide the secure attachment needed for consistent chain engagement. The high‑strength class 10.9 rating ensures that the bolts will not stretch or deform under the sudden load spikes that occur during rapid gear changes.

Installation is straightforward for both professional mechanics and DIY enthusiasts. After removing the old bolts, clean the mounting surface, apply a thin layer of thread‑lock compound if additional security is desired, and insert the new bolts with the supplied socket insert. Tighten to the manufacturer‑specified torque, typically between 30 and 35 Nm, to achieve optimal clamping force without over‑stress. The double‑lock system eliminates the need for periodic retightening, allowing you to focus on riding rather than maintenance.

Because the kit includes fully threaded bolts, it can be used in applications where the sprocket position may need adjustment. Riders who experiment with different sprocket sizes will appreciate the flexibility offered by the fully threaded design, which allows for fine positioning without sacrificing strength. This adaptability is especially valuable for custom bike builds where chain tension and sprocket alignment are critical to performance.

In addition to off‑road motorcycles, the kit is compatible with many dual‑sport and adventure bikes that share the same M8 bolt pattern. This versatility makes the BOLT kit a valuable addition to any rider’s toolbox, ready to be deployed whenever a sprocket fastener is required. The kit’s components are also suitable for use in high‑performance street motorcycles that demand the same level of durability and precision.

Why Choose Us

BOLT has a reputation built on decades of experience supplying high‑performance hardware to the powersports industry. Each component in this kit undergoes rigorous testing, including tensile strength verification, corrosion resistance assessment, and dynamic load simulation, ensuring that the bolts meet or exceed OEM specifications. Our quality control process includes ultrasonic inspection and dimensional verification to catch any imperfections before the product reaches the customer.

Our manufacturing process incorporates precision CNC machining and controlled heat‑treatment cycles that produce a uniform microstructure throughout the alloy steel. This results in consistent hardness and fatigue resistance, which are critical for maintaining bolt integrity under repeated loading cycles typical of off‑road riding. The heat‑treatment process is calibrated to achieve the exact hardness range required for class 10.9 performance, balancing strength with ductility.

Customer support is a cornerstone of the BOLT brand. Buyers receive access to a dedicated technical helpline staffed by engineers familiar with motorcycle drivetrain systems. Should any question arise during installation or after‑market use, the support team provides prompt, knowledgeable assistance to resolve concerns. We also offer detailed installation guides and video tutorials that walk users through each step of the process.

Finally, the kit is backed by a limited lifetime warranty that covers material defects and workmanship errors. This warranty reflects BOLT’s confidence in the durability of its products and offers riders an added layer of protection for their investment. The warranty terms are straightforward: replace any defective component at no cost, and receive a full refund if the product fails to meet the advertised specifications.

FAQ

What motorcycles are compatible with this sprocket bolt kit?

The kit fits all Japanese and most European full‑size off‑road motorcycles that use an M8 bolt pattern, including many dual‑sport and adventure models. Check your bike’s service manual for exact specifications.

Do I need any special tools to install the bolts?

No special tools are required. The kit includes an 8 mm socket insert that works with standard socket wrenches. A torque wrench is recommended to achieve the correct tightening torque.

Can the bolts be reused after removal?

Yes. The alloy steel construction and zinc plating allow the bolts to be removed and reinstalled multiple times without loss of strength, provided the thread‑lock patches are still intact.

How does the double‑lock system work?

The Fuji metal‑locking nut features a built‑in lock‑wire that resists rotation, while the thread‑lock patch on the bolt cures anaerobically when tightened, forming a chemical bond that further secures the joint.

What warranty coverage does BOLT provide for this kit?

BOLT offers a limited lifetime warranty that covers any material defects or workmanship issues. If a bolt or nut fails due to a manufacturing fault, BOLT will replace the defective part at no cost to the customer.
