Silver Spinner Nut for Threaded M5 x 0.8mm Shaft
This Spinner Nut is designed to fit any prop adapter with a Metric M5x0.8mm 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 M5x0.8mm Spinner Nut has a base that is 12.5mm in diameter, an overall length of 17.3mm and weighs 2.6 grams (0.09 ounces). The prop nut threads are 13mm deep, and it requires a 2.0mm diameter tool shaft to tighten it.
