Free online calculation tools for structural design according to Eurocodes. Excel App. Our products are supplied all over the country and also exported worldwide to different industries where Class 8.8 Studshas varied applications. Properly torqued bolts will provide the maximum amount of clamping force under load. Refer to the charts to find the ideal tightening torque. Spring Design Apps Grade 8 bolts are the strongest commonly used bolts outside of industrial applications. We hope this guide on SAE bolt tightening torques has helped you with your project. Electronics Instrumentation 400 MPa for classes 4.x, 500 MPa for classes 5.x, 600 MPa for classes 6.x, 800 MPa for classes 8.x, and 1000 MPa for classes 10.x. Or, contact me via email (fix the punctuation). For fastening bolts used in different products and Medium Carbon Alloy Steel, Quenched and Tempered. In Brief: SAE Bolt Torque Chart Grade 2, Grade 5, Grade 8, Bolt Torque Charts for Grades 2, 5, and 8. Grade 8. The design resistance of a group of fasteners may be taken as the sum of the design bearing resistances, For preloaded bolted connections which are slip-resistant at the Serviceability Limit State or the Ultimate Limit State the corresponding shear load, According to EN1993-1-8 3.6.1(4) the design shear resistance, According to EN1993-1-8 Table 3.4 the bearing resistance, According to EN1993-1-8 3.6.1(12) where bolts transmitting load in shear and bearing pass through packing plates of total thickness, According to EN1993-1-8 3.8(1) for long joints where the distance between the centers of the end fasteners measured in the direction of load transfer is more than 15, According to EN1993-1-8 Table 3.4 for countersunk bolts the tension resistance. It should be noted that grade 8 nuts are designed to mate with grade 8 cap screws/bolts. Strength (psi) Grade Identification Marking Compatible Nuts Min. They show examples of the typical bolt grade markings for each bolt grade. The size column also includes the thread count. SAE bolt grades indicate the strength of the bolt. COPYRIGHT 2020 LIGHTNINGBOLTANDSUPPLY.COM. Hardware, Metric, ISO Videos Design Manufacture 120,000. The yield strength fyb and the Grade 8 hex cap screws are made to a much higher precision than grade 8 bolts. Downloads Made from Grade 8 steel, these screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. Values in italic are greater than the double shear capacity of the bolt. Bearing Apps, Specs & Data Engineering Book Store Hardware, Metric, ISO Shear strength must be calculated, Click "Accept" if you agree or click "Manage" to learn more and customize cookies. All grade 8 bolts have the same tensile strength per square inch. Sharon has expertise with both woodwork and metalwork, so she's always prepared for any job!
