Minimum Tensile Stress Hex Bolts HEX BOLTS - MINIMUM TENSILE STRESS (MPa or N/mm²) Minimum Proof Load Hex Bolts. JEGS Sport Torque Wheels are engineered and tested to meet or exceed SAE (Society of Automotive Engineers) J2530 for radial fatigue, cornering fatigue and impact fatigue. • Clamp load is approximately 75% proof load. To solve bolting groups in general: 1) Find the bolt group centroid 2) Determine directional vectors for each bolt with distance Rn 3) Calculate direct shear load for both the weight and applied load (Fv) 4) Calculate Reaction Moment (M) at the bolt group centroid. The proof load is usually considered to be the absolute. This figure shows that the A490 bolt has a higher load-carrying capacity than the A325 bolt and that both can carry more load than the hot-driven rivet. 8 Metric Studs Metric Screws Drain Plugs and Gaskets Body Clips. If there is no bolt preload in loaded bolt joint, the bolt load is equal to the joint load.
