M8 8mm Front Or Rear Axle Set (48mm)

The M8 8mm x 28mm-86mm Axle Set is crafted from Grade 8.8 carbon steel for high strength and corrosion resistance. It is designed for scooters with an 8mm bearing bore and includes four gaskets to allow length adjustments between 44mm and 48mm. This versatility makes it suitable for stunt scooters, dash-style models, and adult-ready kick scooters with substantial load capacity (800+ pounds). The set provides durable fastening essential for both front and rear axles and fits a wide range of wheel assemblies where precise axle length is critical.
Hex Lock Axle 77mm for 8mm Bores

This Hex Lock M8 axle set features a 77mm length suitable for longer axle requirements. The bolts are made from high-quality steel with strong oxidation and corrosion resistance, designed for durability in daily scooter use. Four gaskets allow adjustment within a 4mm range (73–77mm), enabling secure fit across various front or rear wheel configurations. The product targets kid and adult kick scooters, inline skates, and related equipment that rely on reliable, easy-to-install axles with broad compatibility for 8mm bearing bores.
47mm Front/Rear Allen Screw Set

The 47mm Allen axle set offers a compact option for scooters with shorter axle needs. Made from steel with strong resistance to oxidation and corrosion, these screws are durable for long-term use. The length is compatible with 8mm bores and includes four gaskets to adjust the effective length within a narrow range (43–47mm). This makes them suitable for mid-range kids’ scooters and micro models where space constraints necessitate precise axle sizing. It is commonly used on rear wheels but can support front applications on compatible frames.
Front/Rear Hex Lock 54mm Axle Set

The 54mm Hex Lock axle set is designed for scooters needing a longer 8mm axle with adjustability via four gaskets. The 50–54mm adjustable range accommodates a variety of wheel and deck configurations, supporting stable front and rear wheel connections. Steel construction ensures durability and resistance to daily ride stresses, making it a practical choice for kids’ and light adult scooters that demand reliable performance and straightforward installation.
45mm Front/Rear Micro Scooter Axle

This 45mm axle option focuses on micro and small-wheel scooters, where compact axles are essential. Made from steel for durability and corrosion resistance, it is designed for 8mm bearing bores and aligns with rear or front wheel setups. It often serves as a rear-wheel specific component but can be compatible with front wheels in compatible frames. The short length supports lightweight builds and tighter geometries commonly found in kids’ micro scooters and travel-friendly designs.
Buying Guide: Key Purchase Considerations
- Axle length vs bore: Confirm the bearing bore diameter (8mm) and choose a length that fits your scooter’s deck, wheel hub, and fork spacing. Adjustable lengths with gaskets offer flexibility across models.
- Material quality: Look for Grade 8.8 carbon steel or high-quality steel for strength, rigidity, and corrosion resistance to withstand daily riding and exposure to moisture.
- Compatibility: Check compatibility with your scooter’s wheel count (2-, 3-, or 4-wheel) and whether the axle is intended for front or rear use. Some sets are cross-compatible but verify fitment with your frame.
- Gasket system: A gasket-enabled design helps fine-tune the effective axle length and improves sealing against dirt and moisture. Ensure the gasket count matches your length range.
- Installation and tool needs: Ensure you have the appropriate Allen wrench size (commonly hex keys for M8 bolts) and follow torque guidelines to avoid over-tightening.
- Durability vs weight: For balanced performance, select an axle with strong steel composition that provides resilience without adding unnecessary weight to stunt or everyday scooters.
- Safety considerations: Properly seated axles reduce wobble and improve steering control. Inspect axles periodically for wear, deformation, or rust and replace as needed.
