Submit. Last. Calculation Basis SR1 Software calculates, in accordance with VDI 2230, high-stress bolted joints with concentric or eccentric strain and load. Boltplus Bolt Load Calculation is a free app and what makes it different from similar apps on the market is the speed, ease of use and ability to save all the calculations against a project. K values: waxed (e.g. pressure wax as supplied on high strength nuts) = .10, hot dip galvanized = .25, and plain non-plated bolts … from precision medical instruments to high-performance robotic solutions, FUTEK products are designed to work in the most demanding environments — even on Mars. Both lateral (single and double shear) and withdrawal capacities can be determined. Selecting “Auto Spacer” 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). Accuracy of Bolt Preload Based on Bolt … EZ Calc - Bolting Calculator, Enerteq's oline tool for estimating Required Torque Values. the bolt load is transferred from the Tensioner to the joints hexagon or round nuts. A t = Tensile Shear Area of Bolt S p = Proof Load of Bolt (or some percentage less than 100% of yield load of bolt, typically 85 % of yield S y) c = 0.75 For connections requiring reuse c = 0.89 For permanent connections . Date :-01.01.2003. If the joint is exposed to cyclical loads, too little clamping force can shorten the bolt’s fatigue life. 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: Higher or lower values of clamp load can be used depending on the application require- in.) Calculate bolt design stress and design load from bolt diameter and yield stress or proof stress. Clamp load (lb.) Single. 2. Bolt Torque Calculator; US Bolts - Tensile Strength and Proof Loads ; Proof Load. Gross Area. Bolt Load Calculator. Name * First. The calculation makes enables graphical representation of load-extension diagrams and scale drawings. Open --> Bolt Preload Tension Force Calculator. Shear Capacity at 160N/mm THREADS IN SHEAR PLANE. Hydraulics. COMMITTED TO SUSTAINABLE PRODUCTIVITY 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. Use to determine Torque, Bolt Load and Percent Yield of Maximum Load of Bolts. 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. F v,Ed is the applied shear load and F v,Rd is the shear resistance of the bolt. Learn More. The calculator below can be used to calculate the torque required to achieve a given axial bolt force or load. 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 . RE: ASME flange calculations design bolt load Vs. applied bolt load … The minimum required bolt load divided by the number of bolts in the flange will determine the minimum f, or force, needed to use the torque equation. This uses the equations from ANSI B1 1-1974 and B18.3.1-1978 which calculates the area carrying the tensile load from the mean of the pitch diameter and the minor diameter. F t,Ed is the applied tensile load and F t,Rd is the tension resistance of the bolt. Caution. Actually what I do not understand in ASME is that the bolt load used for design seems different from the true bolt load (as the one I describe just above). Bolt Load Capacity Tables To BS5950 Part 1. Tightening torque to preload a bolt Metric thread : M1 M1.2 M1.6 M2 M3 M4 M5 M6 M8 M10 M12 M14 M16 M20 M24 M30 M36 M42 - 3.6 4.6 4.8 5.6 5.8 6.8 8.8 9.8 10.9 12.9 Bolt Torque Calculator. An example verification calculation is provided in Fig 4 for a steel plate 1m diameter and 20mm thick impacted by a mass of 0.253kg at 6.581m/s using CalQlata's Plates calculator. Explore the possibilities. Try this bolt pattern force distribution calculator, which allows for applied forces to be distributed over bolts in a pattern. Clamp load is also known as preload or initial load in tension on bolt. A material must remain in its elastic region when loaded up to its proof load typically between 85-95% of the yield strength. 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. kN. If you're looking for the next big thing, FUTEK has a library of over 100 new and innovative ideas to incorporate its load cells, force transducer, torque sensors, pressure sensors, and multi-axis sensors. Email * Website. Force = Bolt Load = ? Informate’s bolt load values are independently verified to ensure leak-free joints, every time. Tensioning sequence information. The load will vary for each bolt. With too little clamping force, the joint may loosen. See also this calculator and this table. Due to a variation in friction we recommend in extreme cases to check with the bolt manufacturer, as this chart represents a guideline only. mm. 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). After calculating the torque, ensure the bolts are not over-stretching and exceeding their yield strength, or some predetermined design stress. Step 1 - Enter Information. 1) Enter thread diameter nominal value in section Thread Size.Click on info button for more info. 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). 2. Area = Tensile Stress Area = 0.6057 sq.in (For 1” bolt from ASME PCC-1) Force (Bolt Load) = 105000 X 0.6057 = 63598.5 lb Kindly confirm if this can be used to calculate bolt load before using T=KFD to calculate the torque value Bolt Load Calculator Please note that the above data is based on bolts lubricated to manufacturer’s spec.
