Applications and Benefits:
Self-Tapping Screws tap their own threads as they are being driven into a pilot hole. Sharp-tipped self-tapping screws, often with Type 17 Points, have the ability to drill their own holes in soft materials. Self-tapping screws with flat points will need pilot holes drilled before they can be installed.
Self tapping screws VS. Self drilling screws
The difference between self-tapping and self-drilling fasteners is that self-tapping screws will tap a hole into a soft material, self-drilling screws can drill a hole into anything from metal to wood meaning no pilot hole is needed.
Two main categories of Self Tapping Screws:
1. Thread-Forming Screw
Before using this self-tapping screw, it is recommended that a pilot hole is drilled into the material. As thread-forming screws have a flat nose, it makes the drilling process easier and is used when fastening plastic together.
2. Thread-Cutting Screw
This self-tapping screw does not require any preparation. As it has a pointed tip, it is not necessary to create a pre-drilled pilot hole. Thread-cutting screws can pierce a small entry hole while being driven into the material the thread is being created.
Self-tapping screws are used where an application requires regular maintenance and regular easy access. These screws are useful in situations where products must be assembled and disassembled, such as access panels or even furniture.
