2. The calculation makes enables graphical representation of load-extension diagrams and scale drawings. 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. Proof load is defined as the maximum tensile force that can be applied to a bolt that will not result in plastic deformation. Values calculated using industry accepted formula T = KDP where T = Torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt clamp load, lb. 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 is calculated by arbitrarily assuming usable bolt strength is 75% of bolt proof load (psi) times tensile stress area (sq. Quick Input Quick input provides input of all data in only one dialogue window. F t,Ed is the applied tensile load and F t,Rd is the tension resistance of the bolt. Too much clamping force can also cause severe problems. Bolt Load Calculator Please note that the above data is based on bolts lubricated to manufacturer’s spec. 2. 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). The accuracy of all calculations performed in the shock load calculator is … 1) Enter thread diameter nominal value in section Thread Size.Click on info button for more info. See also this calculator and this table. K – constant d – diameter of bolt (m, in) F – axial bolt force or load (N, lb) Submit. Clamp load (lb.) To achieve the benefits of the preloading, the clamping force must be higher than the joint separation load. Use to determine Torque, Bolt Load and Percent Yield of Maximum Load of Bolts. 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. 8) NOMINAL BOLT SLIP LOAD - This is the nominal slip load shear loads applied to the joint should be below this value. Tensioning sequence information. 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. Tension elements: Elongation due to axial load Calculator: Calculates elongation (as well as stress and strain) for prismatic elements subject to axial force.. Wood tension element capacity Calculator: Calculates capacity of a wood tension element based on allowable tension on net area (reduced by bolt holes) and, if desired, row and group tear-out. Some notes from ISO 898 metric screw threads standards: 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. Bolt Torque Calculator; US Bolts - Tensile Strength and Proof Loads ; Proof Load. Accuracy. EZ Calc - Bolting Calculator, Enerteq's oline tool for estimating Required Torque Values. About this Calculator What is it for? 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: The calculator is generic an can used for imperial and metric units as long as the use of units are consistent. Both lateral (single and double shear) and withdrawal capacities can be determined. Caution. Gross Area. After calculating the torque, ensure the bolts are not over-stretching and exceeding their yield strength, or some predetermined design stress. BOLT ULTIMATE STRENGTH CALCULATORS. That figure is about right for a low tensile bolt. The lower calculation table considers simulaneous axial (Fa) and shear … Bolt Load Calculator. COMMITTED TO SUSTAINABLE PRODUCTIVITY 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. Due to a variation in friction we recommend in extreme cases to check with the bolt manufacturer, as this chart represents a guideline only.
