FAQs
Does this fit my 2020 Yamaha YZF250?
No, this specific bolt is designed for the 2014-2018 model range for the YZF250.
Can I use a socket wrench to tighten this?
It is not recommended. The bolt is designed for hand-tightening, and using a socket wrench may overtighten and damage the component.
What is the material of the shaft?
The shaft is made of durable stainless steel for strength.
Why is the head made of aluminum?
The aluminum head reduces total weight while providing a durable, grippy surface that is easy to manipulate.
How do I prevent stripping the plastic threads in the airbox?
Always start the bolt by turning it counter-clockwise until you feel it drop into the thread path, then proceed clockwise.
Troubleshooting
Bolt feels difficult to thread
Back the bolt out completely, ensure no debris is in the housing hole, and restart the threading process slowly using the tapered lead-in.
Bolt head is loose during vibration
Ensure the air filter cage is properly seated and flush against the mounting surface before tightening the bolt.
Pros and Cons

- Improved grip for faster filter maintenance

Setup, Compatibility & Care
To install, simply hand-thread the bolt into the existing airbox mounting point. Due to the aluminum head construction, do not use impact drivers or excessive torque, as this may damage the component or the mounting surface.
