Custom Made Thread Cutting Screw
A thread-cutting screw is designed to create its own mating internal thread in a pre-drilled pilot hole in ductile materials like plastic, wood, soft metals (e.g., aluminum, zinc die-castings), or soft alloys. This eliminates the need for a separate tapping operation, saving time and cost. The type of thread cutting screw shafts include Type-1, Type-23, Type-25, and Type-F. These “types” refer to the end-point configurations of the screw shaft and have different application purposes.
