Can other companies’ clubheads be used with the Spiralock® system?
Yes. The heads simply must be tapped with the proprietary Spiralock® 30° ramp threading. We offer this service for $22/head for non-TWGT clubhead models, with a 2-3 week turnaround time. However, there are aluminum hoel O.D. requirements on any clubhead to enable the threads to be tapped in the hosel bore, so please contact us for further details.
