Difference Between Sheet Metal And Self Tapping Screws

Why drill a bunch of holes into a metal sheet wearing out a drill bit when you can use these guys.

Difference between sheet metal and self tapping screws.

Sheet metal screws are very strong because the metal may be resistant. It can be hard for you to know the difference between the two. Hopefully this gives you a better understanding of the differences between metal and. If the tip is flat it is thread rolling rolling or extruding threads and creating zero clearance between screw and material.

They both have a sharp end to fit in the metal. Here are the differences between both fasteners. What is the difference between a self drilling screw and a self tapping screw. And they are even available in the same materials.

Self drilling a screw that can well self drill through various gauges of metal materials without predrilling. These screws have two sets of threads with alternating heights. Whichever name is used these names are for screws that form mating threads tapping the threads. Similar to sheet metal screws but self drilling screws have a drill shaped point to cut through sheet metal or steel which eliminates the need for drilling a pilot hole we offer the best self drilling screws that are designed for use in soft steel or other metals.
