• Size - Thread diameter: M8; Outer diameter: 12mm/0.47"; Inner hole: 5mm/0.2"; Nut outer diameter: 12mm/0.47"; Length: 9.6mm/0.38", 6.4mm/0.25". Color: Purple. Disc nail screws come in a variety of colors, so you can choose according to your tastes and needs, and are also perfect for updating the appearance of your bicycle.
• Material - Made of aluminum alloy, high strength, lightweight, corrosion resistant, wear resistant and long life.Anodic oxidation treatment on the surface prevents acidification and resists fading.
• Features - High-precision CNC-machined aluminum alloy sprocket bolts have a smooth finish without burrs, and standard threads distribute force evenly to prevent slippage during rotation.
• Application - The disc screw fixes the brake disc to the hub and ensures the normal operation of the braking system.Suitable for mountain bikes, road bikes, folding bikes, cargo bikes, BMX, downhill bikes, etc.
• Note - Secure one end of the nail with a disc nail wrench and remove/install from the other side with a 5mm hex wrench.Too loose installation may cause parts to fall off, and excessive tightening may damage the aluminum material.
Chainring bolts made of aluminum alloy have high strength, are lightweight and sturdy, are resistant to corrosion, are not easy to rust, have excellent wear resistance and are not easily damaged, so they can be used for a long time.The surface is anodized, which effectively prevents oxidation and is resistant to fading.
The aluminum alloy sprocket bolts are manufactured using high-precision CNC machining for a smooth, burr-free appearance, and the standard thread specifications evenly distribute force to prevent slipping during rotation.
Disc screws are used to fix the bicycle brake disc to the wheel hub, ensuring the normal operation of the brake system.Widely compatible with mountain bikes, road bikes, folding bikes, cargo bikes, BMX bikes, downhill bikes, etc.
Secure one end of the nail with a disc nail wrench and remove or install from the other end with a 5mm hex wrench.Be careful not to tighten too loosely as parts may come off, and too tightly to damage the aluminum alloy material.
