Types of Self-Tapping Stainless Screws

18-8 Stainless Steel Self-Tapping Screws

18-8 stainless self-tapping screws are Type A screws made from one of the following austenitic alloys: 303, 303Se, or 304—all of which are characterized by having a chromium content of 17-19% and a nickel content of 8-10%. 18-8 stainless steel is used in products that require general atmospheric corrosion resistance. We supply a variety of 18-8 stainless screws, including square and Phillips flat, oval, pan, and truss head.

316 Stainless Steel Self-Tapping Screws

316 stainless steel is very similar to 18-8, but 316 contains 2-3% molybdenum while 18-8 does not. While these two types of stainless steel are almost identical in terms of strength, 316 stainless steel has a higher degree of corrosion resistance due to the added molybdenum. We supply 316 stainless steel self-tapping screws in a variety of styles, including slot hex washer head and Phillips flat, oval, pan, and truss head.

Self-Tapping Screws vs Self Drilling Screws

Self-tapping and self-drilling are terms that are often used interchangeably, however; these two types of screws have small distinctions that differentiate them from one another.
  • Self-tapping screws, for one, create their own threads as they are driven into a hole and do not require matching female threads in the same way nuts and bolts do. However, self-tapping screws do require a pre-drilled hole in order to properly fasten two materials together.
  • Self-drilling screws, on the other hand, have a point similar to that of a drill bit, allowing them to create their own hole and threads in one sweep, and therefore, do not require a preexisting hole.
