The GP Hub Screw is an official GP spare part designed for GP engines fitted with the blue anodised propeller hubs. It is compatible with a wide range of GP petrol engines, including the GP 38cc, 61cc, 76cc, 88cc, 123cc, 176cc, 176cc EVO and 178cc.

Ideal as a replacement or workshop spare, this genuine GP prop hub screw is suitable for maintaining your engine and propeller hub assembly.

Important: Older GP engines fitted with the previous silver chromed propeller hubs require a different taper-fit hub screw. If you have an older silver chromed hub and require the correct screw, please contact us before ordering.
