ProSpin 8mm x 1.0 Prop Nut with 8mm Bushing (PN81)

ProSpin 8mm x 1.0 Prop Nut with 8mm Bushing

The ProSpin 8mm x 1.0 Prop Nut with 8mm Bushing is a replacement or alternate-fit mounting set for compatible ProSpin aluminum spinner installations. It includes an 8 mm prop nut with a 1.0 mm metric thread pitch and a matching 8 mm bushing.

Choose this part when your engine or motor has an 8 mm x 1.0 mm threaded propeller shaft. Unlike the standard prop nuts supplied according to spinner size, the PN81 is selected according to the shaft thread required by the engine or motor.

📏 Choosing Between the PN81 and PN82

ProSpin offers two prop nuts with an 8 mm diameter. They have different thread pitches and are not interchangeable.

Important: Both parts have an 8 mm diameter, but the thread spacing is different. The correct choice must match the complete shaft specification.

Understanding the 8mm x 1.0mm Size

• 8 mm: Nominal thread diameter
• 1.0 mm: Distance between the metric threads
• 8 mm bushing: Matching bushing supplied with the prop nut

Compatibility

The PN81 is intended for compatible ProSpin spinner installations on an engine or motor with an 8 mm x 1.0 mm threaded propeller shaft. Compatibility is determined by the shaft specification, not by spinner diameter alone.

• Compatible shaft thread: 8 mm x 1.0 mm
• Included bushing size: 8 mm
• May replace a standard ProSpin prop nut when a different shaft thread is required
• Not compatible with an 8 mm x 1.25 mm shaft
• Not a universal-fit prop nut
• Spinner and propeller are not included

Package Includes

• 1 x ProSpin 8mm x 1.0mm prop nut
• 1 x 8mm bushing

ProSpin spinner, propeller, engine, motor, and additional mounting hardware are not included.
