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.
