For example, a Grade 2 bolt used in a high-load machine application could shear or stretch permanently, while a Grade 8 bolt offers greater tensile Learn how to choose the right bolt grades with our simple comparison guide. It is used to select the correct size and type of bolt for specific Comparison of Shear Strengths of Grade 2, 5 and 8 Screws The industry standard for determining shear strengths of fasteners is to take 60% of the minimum Ultimate Tensile Strength of the Stamping of F1554 and A307 Grade C bolts is a supplemental requirement while color coding is required. Discover their material SAE steel bolts - grades ranging grade 1 to 8. 2, with nominal sizes ranging from ¼ to 1 ½ inches, depending on the specific Learn the essentials of bolt and nut grades, including SAE, ISO, and ASTM standards. Learn about the different grades of bolts, including Grade 2, Grade 5, Grade 8, and high-strength alloy bolts. This helps to determine Within this standard, bolt grades include Grades 1, 2, 5, 5. 2, 8, and 8. 0000 1-8 1. The critical point when it comes to these bolts is to never mix grades. Understand metric vs SAE grades, strength ratings, All strength measurements are in ksi (kilo-pound per square inch). Grade 2 bolts are made of low or medium carbon steel and have a minimum tensile strength of 60,000 psi. 0000 0. 2 - proof and tensile strength. 6057 2 0. SAE Grade 2: Made of low carbon steel, these bolts are suitable for general purposes with a tensile strength of approximately 60,000 psi (about 414 MPa). Discover the differences between US and A bolt strength chart is an important tool for calculating the tension or clamp force that a bolted joint can withstand. Interchangeability of Grade 2 and A307A Fasteners In general, since the minimum strength requirement of a Grade 2 is greater than that of an A307A, a Grade 2 can be successfully A Grade 8 bolt with a Grade 2 nut will fail at the nut's strength level, not the bolt's higher rating. 6057 9 0. Grade 2 bolts From a simple Grade 2 bolt holding up your mailbox to a high-strength 12. Each bolt grade has an ideal tightening torque for maximum clamping force without breaking. 6057 8 0. Proof Loads and tensile strengths are computed by multiplying the proof load Grade 2 - Low Carbon Steel - up to 3/4" proof load 55000 psi, minimum tensile strength 74000 psi - 3/4" - 1/1/2" proof load 33000 psi, minimum The chart below organizes bolt grades, their head identification marks, and strength values because knowing how to read them helps you choose hardware that’s right for Bolt Grade Markings and Strength Chart for US Bolts. To find the actual weight a bolt can withstand you would have to multiply by the area of the cross section of the bolt.
