Load Calculator Quickly find the tensile, yield, proof, and estimated shear strengths of your bolts. Select your Bolt Size and Grade, your result will be calculated. Tensile Strength Calculator. at least 640MPa. The following values are required as inputs to the calculation: 1) BOLT GRADE - Enter the two numbers comprise the bolt grade here and the approximate bolt ultimate strength and yield are calculated. Strength of the bolt or screw. for which no breaking and proof loads are indicated in ISO 898-1, as well as to UTS (Ultimate tensile strength), often shortened to TS (tensile strength) or ultimate strength is the maximum stress that a material can withstand while being stretched or pulled before failing or breaking. thick washers and cleaned threads. The strength of a nut or bolt thread cannot be viewed in isolation without considering the inter-dependence which both elements have on the strength of the assembly. 120000psi (proof load stress) 1.15 (arbitrary) I don't think tensile or ultimate is used in this case. If you have any questions, please contact our … Whilst, there are innumerable alternative welding options (most of which are uniquely suited to particular applications), there are two general purpose methods that can be interchanged according to particular requirements (cost, time, access, procedures, etc.). US Bolts: Head Marking Grade and Material Nominal Size Range (inches) Mechanical Properties ; Proof Load (psi) Min. EICAC - Design ByFat Buddha Designs. In the case of a 8.8 grade bolt the first figure signifies that the Tensile Strength is at least 800MPa. FUTEK's Donut/Thru Hole Load Cells are major players when measuring the tightening of load directly. steel with designations 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9. BOLT ULTIMATE STRENGTH CALCULATORS. Help support us by using our affiliate links below. These values vary depending on the bolt’s diameter and number of threads per inch. FUTEK's Donut/Thru Hole Load Cells are major players when measuring the tightening of load directly. Proof load is defined as the maximum tensile force that can be applied to a bolt that will not result in plastic deformation. BOLT SIZE: 0BA 1BA 2BA 3BA 4BA 5BA 6BA 7BA … Related Topics .
