what is the shear strength of a 1 2 grade 8 bolt What is the shear strength of a grade 8 bolt Six raised dashes identify the grade 8 bolt a high strength item in high demand Its quenched and tempered medium carbon alloy steel allowed for an impressive tensile strength of 150 000 psi which is higher than the 64 000 psi of a grade 2 bolt
Proof Loads and tensile strengths are computed by multiplying the proof load stresses and tensile strengths stresses by the stress area of the thread As 0 7854 D 0 9743 n squared where D equals nominal diameter in in and n equals thread per inch Tensile Strenght Proof Load Tensile Strength for Grade 2 5 8 M2 is the partial safety factor for the resistance of bolts in accordance with EN1993 1 8 2 2 2 Table 2 1 and the National Annex The recommended value in EN1993 1 8 is M2 1 25 Shear strength of bolts The shear resistance of the bolt per shear plane F v Rd is provided in EN1993 1 8 Table 3 4 F v Rd v f ub A M2

Grade 5 Medium Carbon Steel Quenched and Tempered up to 1 proof load 85000 psi 1 1 1 2 proof load 74000 psi minimum tensile strength 105000 psi 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 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 Specification
The shear strength of a bolt refers to its capacity to withstand maximum shear force without breaking when subjected to a lateral external force We can understand the calculation method standards and some specific values of bolt shear strength The most common SAE bolt grades are Grade 2 Grade 5 and Grade 8 Metric Bolt Grades Chart with Strength Chart The most common bolt grades are 8 8 10 9 and 12 9
