The Aerotech PowerCoil RH50 shaft is not available in a .350" tip size. Aerotech is only manufacturing the shaft in a .335" tip size these days. You would have to shim the .335" shaft to fit the .350" hosel bore. Our SHIM15 or Universal Plastic Shim (BB9018) both work well for this installation.
Depending on which manufactures clubhead you have an adaptor to install a .335" shaft maybe available from them.
