MS2.0 Countersunk FH Screw M3x8mm for Aluminum Chassis - Yokomo ZC-F38SH  [ZC-F38SH]

Precision Flat-Head Countersink Screw

This Yokomo ZC-F38SH screw set is designed for MS2.0 aluminum chassis, providing FH (flat head) countersunk fastening optimized for 1.5mm plate profiles. The head uses a 120° taper instead of the usual 90° so it sits flush and keeps clamping consistent.

Made from steel with tight machining tolerances to minimize play between the screw head and chassis countersink. Correct seating lowers local deformation and helps preserve chassis alignment, aiding repeatable balance and stiffness tuning during setup and track use.

Installation tips: use the correct hex driver, start the screw aligned in the countersink before final torque, and apply modest torque to avoid stripping threads in thin aluminum. Packed as M3x8mm, 4pcs, and compatible with MSR-020A and MSR-020 chassis series.
