Volume of Solids Calculators These metric bolt torque charts show the ideal tightening torque for class 8.8, 10.9, and 12.9 bolts for both wet and dry tightening. Finishing and Plating Refer to the charts below, which show the ideal tightening torque for each bolt grade for a variety of sizes. If you might need to look up the ideal tightening torque for metric class bolts again, why not bookmark this page so that you can refer to it more easily in the future? Production years: 2015 - present Generation: 2 Type of van: pickup Model variant: Base Figures only valid for coarse thread screws and should be used as a reference guide only as variables such as but not limited to temperature, lubrication, plating and condition of mating threads will change Torque figures. HVAC Systems Calcs J/rad are also alternative units of torque, commonly used when you need the value of torque in calculations of work or power. That figure is about right for a low tensile bolt. They are over 50% stronger than stainless steel thread-locking screws. Calculated values are approximate. 11-13-2011, 07:42 PM. One Size. Fractory Ltd, Suite 4.15, Department Bonded Warehouse, 18 Lower Byrom Street, Manchester, M3 4AP. Note that standard dry torques are normally calculated to produce a tensile stress - or axial force or clamp load - in the bolt that equals to 70% of minimum tensile strength or 75% of proof strength. This calculator uses a practical starting point for all threaded fastener tightening analysis and uses the basic elastic torque-tension equation. | Contact, Home Flat Plate Stress Calcs Bearing Apps, Specs & Data metric, inch. The bolt is stressed up to the proofload value, and if there is no deformation, elongation, or fracture, then the bolt is deemed to have passed. Model# 861618. <> 0000001456 00000 n
