M3x8 Imbus Bolt – 10 pcs

These M3x8 Imbus bolts are practical metric fasteners for small mechanical assemblies, RC aircraft parts, 3D printed components, and workshop projects.

At Craycle, we use M3x8 socket head cap screws as common hardware across multiple models. They are used as motor screws for attaching the motor mount to the motor, usually with 4 screws per motor setup.

We also use this screw in our Spring Lock design as the handle screw for the spring catch mechanism. This makes it useful for hatch and canopy lock systems in Craycle aircraft.
