Thank you for your question, Gerald! The set screw RP152 will use a 1/8 inch hex key, however, please know that this is not always the set screw used on all 13/14 series shower handles as they are sometimes model specific. To be sure this is the correct set screw, please refer to your original owners manual. If you need further assistance, please contact our customer service team directly at 1-800-345-3358 Monday-Friday: 8a.m.-8p.m. EST and Saturday: 9a.m.-6p.m. EST or via email at firstname.lastname@example.org.
Best regards, Edward
