Self-Tapping Screw for CSC Scooters and GY6 50cc Engines

This 4.2x12 self-tapping screw suits several CSC scooter models, among them the Bella Classic 50, Nitro Sport 50, Pug 50, and both the go and go MAX. It holds plastic parts such as front fairings and side covers in place. It belongs to the group of GY6 50cc scooter parts that help keep the scooter body properly put together.

Purpose and Usage

This screw is mainly used to fasten the body. It secures a range of plastic pieces to the frame. If a screw has been damaged or lost, a replacement keeps the body panels seated tightly, which helps the scooter look and fit as it should.

When to Replace

Check your scooter from time to time for screws that have worked loose or gone missing. Panels that move or wobble, or screws with stripped heads, are a sign they need replacing. A scooter that stays firmly assembled is safer to ride.
