Q: Wht do the wings on the self drilling 1/4-20 ceramic coated flathead screws do? Seems as if they would destroy the tap hole size for the thread!

  • A: Hello, the wings enlarge the hole in the fastened material, allowing the threads to pass through without contacting the fastened material. Thank you for your inquiry!
