About Our Self Tapping Screws
A number of pan head and countersunk screws are used for attaching to metal, and a pre-drilled hole is required. Plated in Trivalent Chromium (CR3) zinc 3 microns Driver bit size No 1.
Self-tapping screws are typically used to secure wood, plastic, metal and brick together. There are two types of self-tapping screws, thread-forming and thread-cutting. Thread-forming: Before you can use these screws you will need to drill a pilot hole as the screw itself does not contain a pointed tip.
Self-drilling screws eliminate the need for a pilot hole but can tap as well. Self-tapping screws tap their own threads, but cannot drill through metal and require a pilot hole. These screws are not interchangeable, and mixing up the two can cause many headaches or possible failures in the field.
