Flat-Head Countersunk Screw Specifications

This Yokomo ZC-F38SH FH countersunk screw set is intended for MS2.0 aluminium chassis and is profiled to sit flush on 1.5mm plates thanks to a 120 degree head angle. That angle differs from the common 90 degree form to match the chassis countersink geometry.

The screws are steel and machined to close tolerances to limit movement between the screw head and the countersink. When seated correctly this reduces localized plate deformation and helps maintain consistent chassis geometry for reliable tuning.

Fitment guidance: use a properly sized hex driver, align the screw in the countersink before final tightening, and apply conservative torque on thin aluminium to protect threads. The pack includes four M3x8mm screws and lists compatibility with MSR-020A and MSR-020 chassis variants.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Which driver size should I use for M3x8mm FH screws?

Use a hex driver that matches the screw head socket snugly to avoid rounding; the correct fit improves torque control and reduces wear on the head.

Can these screws be used as replacements on other chassis?

They are optimised for MS2.0 geometry; other chassis that use a 120 degree countersink and M3x8mm fasteners could accept them, but confirm plate thickness and countersink angle before swapping.

How should I avoid stripping threads in thin aluminium?

Tighten in stages, use a driver with good grip, and stop when resistance increases; consider light threadlocker or using steel inserts if repeated removal is expected.
