Silver Spinner Nut for Threaded M8 x 1.25mm Shaft
This Spinner Nut is designed to fit any prop adapter with a Metric M8x1.25mm threaded shaft with normal Right-hand threads.
Spinner Type Nuts work great to dress up the end of a threaded prop shaft on a motor while they securely hold your prop in place. In many AMA events, a spinner type nut is required to meet safety inspection guidelines. These spinner nuts are machined from aluminum alloy bar-stock, and are anodized either clear or black to protect the outer finish. They have a small hole drilled across the tip that a small screwdriver shaft, hex wrench or piece of music wire can be inserted into so the nut can be tightened down against the prop.
The M8x1.25mm Spinner Nut has a base that is 19.6mm in diameter, an overall length of 25.0mm and weighs 9.0 grams (0.32 ounces). The prop nut threads are 18mm deep, and it requires a 3.0mm diameter tool shaft to tighten it.
