These FH (flat head) countersunk screws are made for MS2.0 aluminum chassis applications where a 120 degree taper is required. The head angle is deliberately 120 degrees rather than the common 90 degrees so the head seats flush against 1.5mm thick MS2.0 aluminum plates, improving contact and reducing slight rocking at the mounting points. Material is steel with high-precision machining to keep thread tolerance and head seating consistent across pieces.
This listing is for M3x8mm length, supplied as 10pcs, and is intended for use with MS2.0 aluminum chassis including MSR-020 and MSR-020A platforms. In practice these screws help maintain a square, stable chassis mounting which supports predictable tuning changes to balance and handling without implying any non-RC use.
