Stainless Steel Grades & Strength
The Nut and Bolt Solution Series
A common question is whether stainless steel is stronger that a grade 5 or grade 8 bolt. Stainless commonly comes in grades 18.8 (304) or T316. Stainless steel bolts are rated for corrosion resistance. Bolt strength is rated in PSI (pounds per square inch). A stainless steel bolt has the same PSI rating as a grade 5 bolt (125,000 PSI). A grade 8 bolt has a stronger rating with a PSI of 150,000.
