Choosing Stainless Steel Grades for Self Drilling Screws
October 26, 2023
If you require self-drilling screws in stainless steel, it's important to note: Not all grades of stainless steel offer the same performance for this specific screw style.
Fastener SuperStore carries self-drilling screws in three grades of stainless steel: 410; 18-8 (also known as 304) & 316. Each grade provides different benefits. When it comes to self-drilling screws, it's important to take into consideration the hardness of each grade, as well as what type of material you will be installing the screw into.
18-8 & 316 stainless steel both provide greater corrosion resistance than 410 stainless however they are not hardened. 410 is hardened and much more capable of drilling through metal materials.
Your primary concern when choosing stainless steel self-drilling screws should be the material you will be drilling into. If you are drilling into wood, plastic or even thin aluminum, an 18-8 screw will probably do the job. Drilling into a harder metal will generally require 410 stainless steel. 18-8 or 316 stainless screws are likely to wear down, strip or break when drilling into harder materials.
