How Strong Are Grade 8 Bolts? Grade 8 bolts are the highest grade of bolts under the SAE J429 standard, which means they have the highest strength. Here are their various strength specifications: But now you might be wondering what those PSI numbers really mean. By EngineerExcel. Bolt grades are essential for ensuring that bolted joints are strong and durable enough to handle the intended load with the appropriate safety factor. These alphanumeric designations categorize bolts based on their mechanical properties, such as proof load, tensile strength, and surface hardness.

What Is The Tensile Strength Of A 3 8 Grade 8 BoltShear strength is typically 60% of tensile strength, and the minimum tensile strength of a grade 8 bolt is 150,000 psi. We have an FAQ that addresses this question here: https://www.portlandbolt/technical/faqs/bolt-shear-strength-considerations. Henry:How are all grade 8 bolts the same tensile strength? Grade 8 Medium Carbon Alloy Steel Quenched and Tempered up to 1 1 2 proof load 120000 psi minimum tensile strength 150000 psi Lamalloy Medium Carbon Alloy Steel Quenched and Tempered up to 1 1 2 proof load 145000 psi

Grade 8: These are high-strength bolts marked with six radial lines and have a tensile strength of up to 150,000 PSI. Metric Grades. Metric grades range from 3.6 to 12.9. They are marked by their grade number, for instance, "8.8" or "10.9". Higher numbers represent stronger bolts.
