Bolt Load Calculator Please note that the above data is based on bolts lubricated to manufacturerâs spec. Calculation Basis SR1 Software calculates, in accordance with VDI 2230, high-stress bolted joints with concentric or eccentric strain and load. Single. Explore the possibilities. Thanks a lot for your clarifications. A material must remain in its elastic region when loaded up to its proof load typically between 85-95% of the yield strength. Clamp load is also known as preload or initial load in tension on bolt. kN. The preferred bolt preload for structural applications should be at least 75% of the fastener's proof load for the higher strength fasteners and as high as 90% of the proof load for permanent fasteners. from precision medical instruments to high-performance robotic solutions, FUTEK products are designed to work in the most demanding environments â even on Mars. The Calculators below can be to calculate the ultimate (breaking) load of bolts. K values: waxed (e.g. The Bolt load loss is a direct loss of stud elongation, this is due to many different factors, such as thread deflections, radial expansion of the nut and âbedding inâ of Tensioning sequence information. Force = Bolt Load = ? About this Calculator What is it for? BOLT LOAD CAPACITY TABLES TO BS5950 PART 1, 2000 THE ULTIMATE LIMIT STATE (ie FACTORED APPLIED LOADS) GRADE 4.6 BOLTS In Grade 43, bearing capacity = 460N/mm, for e 2d. Email * Website. Hydraulics.

If the joint is exposed to cyclical loads, too little clamping force can shorten the boltâs fatigue life. Tension tooling, powertrain couplings, and accessories designed for power generation applications. is calculated by arbitrarily assuming usable bolt strength is 75% of bolt proof load (psi) times tensile stress area (sq. The calculator below can be used to calculate the torque required to achieve a given axial bolt force or load. Bolt load is calculated from the design stress (SAE, ISO or ASME), bolt size (UNC, UNF, BSW or ISO) and the tensile area (ANSI or ISO threads). of threaded section of each bolt size. 5) Calculate torsional shear force (Fm) 2) In section Head Size and Type either select one fastener ISO with the "Select Standard for Type" option or enter manually the type and whether the fastener is socket or not in the right part of the page, once you have selected Custom option.. 3) Enter strength class of the fastener. mm. Due to a variation in friction we recommend in extreme cases to check with the bolt manufacturer, as this chart represents a guideline only. The load will vary for each bolt. Clamp load (lb.)
