Parsun Tornillo hexagonal m6x12

GB/T5783-M6X12 is a standard M6x12 hexagon bolt used across Parsun outboard engines in electrical and mechanical assemblies including ignitor cores, rectifier mounts, stator installations, cylinder head sections and intake-side brackets.

The service manuals show this fastener in named assembly positions rather than only as a generic size callout, which makes it a documented service replacement for multiple engine systems.

Compatible with Yamaha 90119-06M73.
