Step 1 - Enter Information. 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. We provide it as a resource for our customers, because the weight of a bolt or assembly is often needed when calculating shipping costs, or jobsite delivery requirements. Tension tooling, powertrain couplings, and accessories designed for power generation applications. Bolt Stress window, displays bolt stress, bolt load and % of bolt yield. The calculator is generic an can used for imperial and metric units as long as the use of units are consistent. Bolt Load Calculator Please note that the above data is based on bolts lubricated to manufacturer’s spec. Instrumentation. joined by a bolted joint. 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. 1) Enter thread diameter nominal value in section Thread Size.Click on info button for more info. But also the possibility to make a request for a special tensioner or enquire about your selections directly in the app. Bolt Load Capacity Tables To BS5950 Part 1. 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 . Single. Clamp load is also known as preload or initial load in tension on bolt. 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. Accuracy of Bolt Preload Based on Bolt … 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. BOLT ULTIMATE STRENGTH CALCULATORS. 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). Bolt Torque Calculator. To download BoltUp, or for a free 7 day trial of the Informate bolt load calculation software go to: joint-integrity.com. Note: tensile axial forces (Fa) applied to the joint will reduce the slip load. 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 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. 2. The Calculators below can be to calculate the ultimate (breaking) load of bolts. K values: waxed (e.g. Try this bolt pattern force distribution calculator, which allows for applied forces to be distributed over bolts in a pattern. Hydraulics. 2. The lower calculation table considers simulaneous axial (Fa) and shear … Some notes from ISO 898 metric screw threads standards: To achieve the benefits of the preloading, the clamping force must be higher than the joint separation load. Force = Bolt Load = ? Both lateral (single and double shear) and withdrawal capacities can be determined. Bearing strength of bolts. F v,Ed is the applied shear load and F v,Rd is the shear resistance of the bolt. RE: ASME flange calculations design bolt load Vs. applied bolt load … 8) NOMINAL BOLT SLIP LOAD - This is the nominal slip load shear loads applied to the joint should be below this value. Submit. If the joint is exposed to cyclical loads, too little clamping force can shorten the bolt’s fatigue life. Due to a variation in friction we recommend in extreme cases to check with the bolt manufacturer, as this chart represents a guideline only. 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 . Proper amount of tensioning of the bolts is vital. That figure is about right for a low tensile bolt. 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). Results are in Newtons. Higher or lower values of clamp load can be used depending on the application require- mm. 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). 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. 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. Quick Input Quick input provides input of all data in only one dialogue window. kN. The Explore the possibilities. Values calculated using industry accepted formula T = KDP where T = Torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt clamp load, lb. Bolt Torque Calculator; US Bolts - Tensile Strength and Proof Loads ; Proof Load. of threaded section of each bolt size. Clamp load (lb.) 5) Calculate torsional shear force (Fm) 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. Calculate bolt design stress and design load from bolt diameter and yield stress or proof stress. The calculator below can be used to calculate the torque required to achieve a given axial bolt force or load. 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 ‘bedding in’ of Definition of the algorithm Name * First. 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 Date :-01.01.2003.

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. Caution. Learn More. COMMITTED TO SUSTAINABLE PRODUCTIVITY The load will vary for each bolt. Calculation Basis SR1 Software calculates, in accordance with VDI 2230, high-stress bolted joints with concentric or eccentric strain and load. This calculator can be used as an aid to help estimate the weight of bolts, nuts, and washers. Last. in.) Tensioning sequence information. 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. Gross Area. F t,Ed is the applied tensile load and F t,Rd is the tension resistance of the bolt. Bolt Load Calculator. Product Lines. 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.
