Fender genuine hardware set for guitars, made with durable materials. - Model: SC-HEX 3/8"-24 NI - Model: BS-SSD/T-6 CR - Part Type: Hardware - Part Type: Hardware Thank you for looking. This is a set of Fender genuine die-cast saddles for a tremolo unit and adjustment set screws. I bought this aiming for the point where the bass becomes stronger compared to a press saddle, but it hasn't had a chance to be used, so I am listing it as unused.
