Bolt Grade Markings and Strength Chart
Tensile Strength: The maximum load in tension (pulling apart) which a material can withstand before breaking or fracturing. Yield Strength: The maximum load at which a material exhibits a specific permanent deformation. Proof Load: An axial tensile load which the product must withstand without evidence of any permanent set.

Understanding Metric Bolt & Screw Grades — & Head Markings!
Apr 10, 2021 · We’ve talked about how to use head markings to determine the different grades and manufacturers of inch-series bolts, but metric bolt and screw head markings are a whole different beast. They’re not a beast we can’t tackle though.
The purpose of the grade marking is to identify the strength level that the fastener has been manufactured to, and the manufacturer's marking is to identify who is responsible for the quality and testing of the fastener.
