This chart helps to identify the grades of bolts using the identification marks on the bolt's head along with the strength and hardness of common grade bolts. Please note the bolt heads may also include the manufacturer's identification stamp, especially with high strength bolts.
A-2 & A-4 Stainless. 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.
Bolt grades are alphanumeric designations that categorize bolts based on their mechanical properties. They determine the maximum amount of load the bolt can handle as well as the method that can be used for tightening the bolt. In general, the higher the grade number, the stronger the bolt.
The bolt grades and strength chart outlines the physical and mechanical properties of various grades of bolts. It includes information on the grade of the bolt, the tensile strength, the type of material, and their common applications.
Bolt strength can be divided into ordinary grade and high strength grade. In this article, we’ll introduce the bolt grades system, the meaning of the bolt head markings grade, you can also check out the metric bolt grades chart.
Learn the different grades and types of bolts so you can find what you need for your DIY or mechanical project. Read this guide to choosing bolts and hardware that fit securely.
Hex Bolt Identification, Markings and Strength Chart. Additonal information on bolts is located at the bottom of the webpage. Note: Some bolts share identical head identification and have significantly different strengths.
Bolt Grade Markings and Strength Chart for US Bolts. Head Marking, Grade, Material, Nominal Size Range (inches) and Bolt Strength.
Bolt Grade Markings & Strength. American Bolts. Metric Bolts. 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.
How to Determine Bolt Strength Grades. Ordinary bolts are divided into Grade A, Grade B (refined bolts), and Grade C (rough bolts). Grade A and B bolts use Grade 5.6 and 8.8 steel, while Grade C bolts use Grade 4.6 and 4.8 steel. High-strength bolts are made from Grade 8.8 and 10.9 steel.
