Yokomo ZC-F38SH High-Precision FH Countersunk Screw M3x8mm for MS2.0 Aluminum Chassis (4pcs)  [ZC-F38SH]

High-Precision FH Countersunk Screw

This Yokomo ZC-F38SH set is an RC-scale FH (flat head) countersunk screw engineered for MS2.0 aluminum chassis. The head has a 120° taper rather than the common 90°, matching the geometry used on 1.5mm aluminum chassis plates to ensure flush seating and consistent clamping force.

Material is steel with high-precision machining to reduce play between the screw head and the chassis countersink. Proper seating reduces local deformation and helps maintain base alignment, which in turn supports repeatable tuning of balance and chassis stiffness during setup and track use.

Installation notes: use a correctly sized hex driver, align the screw in the countersink before final tightening, and torque conservatively to avoid stripping threads in thin aluminum. This listing is for M3x8mm screws supplied as 4pcs, compatible with MSR-020A and MSR-020 chassis series.
