M5 X 25 Countersunk Head Screw for CRG Racing Karts. This screw connects the lower nassau support to the chassis.
Countersunk in shape, and M5 in thread pitch and size, this screw utilizes a 4mm allen to tighten or loosen the nassau panel support.
This pairs well with part 13, to cushion and support the nassau panel once tightened.
