SPINNER NUTS
MECOA SAFETY SPINNER NUTS WITH FULL RADIUS NOSE

Each is made on one of MECOA's computer controlled turning machines
in virtually every US and metric thread size and hex combination.

Do you have a tail heavy plane?
Try our brass spinner nut and add the weight at the best place, far forward so you don't have to add as much.

These also act as a flywheel so your engine will idle more reliably.
