Highley Light Lock Disc – 6 mm Diameter (Model Higllk006)

Description

Two common causes of a propeller and nut spinning off the shaft are:

Any mechanic knows a nut screwed against a second nut locks the first one in place. They call this double nutting. We applied the principle of double nutting to propeller nuts in a special way.
The Lite Lock or Prop Lock replaces the propeller washer as shown in the photos above. A second nut, safety spinner or heavy hub screws against the Lite Lock or Prop Lock and eliminates the problem of propeller spinoff.
Aluminum Lite Locks also compliment the appearance of a safety spinner.
A 1/2 ounce brass Prop Lock adds just a little more nose weight for a tail heavy airplane and goes well with our heavy hub. We have added 10mm and 3/8″ to our brass locking nuts.
