Last. BoltUP - Our online bolt load calculator; Informate - Our advanced calculation and procedure software; IDMS Integrity Data Management System - The complete package for managing Bolted Joints from cradle to grave. Calculate bolt design stress and design load from bolt diameter and yield stress or proof stress. A material must remain in its elastic region when loaded up to its proof load typically between 85-95% of the yield strength. Bolt Torque Calculator; US Bolts - Tensile Strength and Proof Loads ; Proof Load. Bolt Load Capacity Tables To BS5950 Part 1. Bolt Load Calculator. Product Lines. in.) The calculator below can be used to calculate the torque required to achieve a given axial bolt force or load. RE: ASME flange calculations design bolt load Vs. applied bolt load â¦ That figure is about right for a low tensile bolt. Accuracy. Results are in Newtons. The bearing resistance of the bolt F b,Rd should be verified against the applied shear load F v,Ed in accordance with EN1993-1-8 Table 3.4: In the continuation, the paper briefly presents the model for operating bolt load calculation and the method for the calculation of structure elasticity and stiffness matrices and presents a comparative analysis of the results obtained through different calculations and measurements. F v,Ed is the applied shear load and F v,Rd is the shear resistance of the bolt. See also this calculator and this table. Tensioning sequence information. Tension tooling, powertrain couplings, and accessories designed for power generation applications. Bolt Load Calculator Please note that the above data is based on bolts lubricated to manufacturerâs spec. BOLT ULTIMATE STRENGTH CALCULATORS. Gross Area. Too much clamping force can also cause severe problems. Pb = Bolt axial load resulting from yield, ultimate or joint separation load V = Bolt shear load resulting from limit load ... the calculation of the maximum and minimum preloads: (a) The maximum and minimum torques of the specified torque-range plus any prevailing torque (Tmax, Tmin and Tp). By over-tightening the bolt, one may exceed the proof load of the bolt. Hydraulics. Thanks a lot for your clarifications. Explore the possibilities. Quick Input Quick input provides input of all data in only one dialogue window. Both lateral (single and double shear) and withdrawal capacities can be determined. With too little clamping force, the joint may loosen. K â constant d â diameter of bolt (m, in) F â axial bolt force or load (N, lb) Connection Calculator Provides users with a web-based approach to calculating capacities for single bolts, nails, lag screws and wood screws per the 2015 NDS . Caution. Features the Indikon product line of legacy torque and vibration measuring devices. Load Calculator Quickly find the tensile, yield, proof, and estimated shear strengths of your bolts. Email * Website. Torque window, displays torque and defines coefficient of friction Load Graph window, displays bolt stress over a 3 stage time period BTS TAKES THE COMPLEXITY OUT OF BOLT TIGHTENING CALCULATION. Metric bolt grades and strength calculator to show proof strength, tensile strength, Vickers / Brinell hardness, minimum breaking torque and stress area of metric bolts and screws made of carbon steel and alloy steel with designations 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9. Clamp load is also known as preload or initial load in tension on bolt. Finding Tension Loads on Fastener Group This procedure is similar to the shear load determination, except that the centroid of the fastener group may not be the geometric centroid. pressure wax as supplied on high strength nuts) = .10, hot dip galvanized = .25, and plain non-plated bolts â¦ COMMITTED TO SUSTAINABLE PRODUCTIVITY Selecting âAuto Spacerâ from the Spacer drop down menu, allows the software to calculate a suitable spacer thick-ness based on a target Load Transfer Factor (Note the lowest LTF when using bolt tensioning tools is 1.15). After calculating the torque, ensure the bolts are not over-stretching and exceeding their yield strength, or some predetermined design stress. Single. Bolt Load Calculation Software Hydratight introduces Informate: the next generation of software that provides bolt loads and tool pressures on a huge range of flanged joints and clamped connections. Force = Bolt Load = ? the bolt load is transferred from the Tensioner to the joints hexagon or round nuts. 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.
