Harry Higley Light Lock 10 x 1.25mm LLK010 (Box 29)

Description

It is best to use a Prop Lock in a pair or with a Heavy Hub, allowing them to lock together and eliminate propeller spinoff. The Prop Lock would replace the propeller washer, and either a second Prop Lock or a Heavy Hub would screw against the first Prop Lock. These brass nuts weigh 0.5 oz, 3/16” thick, and are 7/8” hex pattern.
