Self-tapping Screws - Sharp Point or Drill Point

by MaryLouise on 07/27/15

Since starting this fastener blog several years ago, one of the most common requests we hear is "I want self-tapping screws".  "I want self tappers".  We hear this more often than not.  We have written several articles on what is the best terminology to use when ordering your screws to make sure you get the right parts and not have to go through the time and expense of returning them to your supplier.  

Summer is here and the building season is booming so this would be a great time to go over this again. Even some employees at fastener supplier houses are confused as to the correct usage of  'self-tapping screw'  Self-tapping is referring to the threads and NOT the point of the screw.  For a more detailed description of fasteners that are often referred to as 'self-tapping', please click here to watch our informative video.

Most of the time, when we hear someone ask for a self tapping screw, they really are looking for a self-drilling screw.  One that has a point sometimes described as looking like a shovel, but in fact, is actually a small drill bit.  The confusion comes with so many different names describing the same screw.  Some are brand names that have just been used for so long that they have become synonymous with the part.   Some names have just been used incorrectly for so long, that you kinda have to give in an say ok.  Like "dove" which is now commonly referred to as "dived". 

Here are the most commonly used terms for the screw that looks like this: 

Self-Tapping Screw

Tek Screws
Self-Drilling Screws
Self-Tapping Screws
Bit Tip Screws

Here is a really helpful self-drilling screw chart that can be used for submittals:
