These are replacement lugs for all 2013-2014 Ronix Bindings. These are Metric Thread M6 Phillips Head Mounting Screws. DO NOT use these on previous years wakeboards that have the 1/4" threads on the screws. Ronix Wakeboards before 2013 did not use Metric Hardware. Placing Metric Thread Screws in Lugs designed for 1/4" Screws will damage the lugs! Set of 4 Screws and Washer Lugs.
