# metric bolt shear strength calculator

The shear strength of a bolt is a measurement of the minimum amount of force needed to break the bolt into two pieces. F atiguesrn h* c odx p fm"E v l limit of metric screw threads for (machine screws, bolts and nuts" Yamamoto). Yield Strength (MPa) Min. Bolt Marking. Allen head bolts can easily be identified as they require the use of an allen wrench. Both lateral (single and double shear) and withdrawal capacities can be determined. P t = p t A t Exact . getcalc.com's Tensile Stress Area of Bolt Calculator is an online mechanical engineering tool to calculate the tensile (critical) stress area or the mimimum area of threaded section of the bolt, in both US customary & metric (SI) units. For bolts, the minimum ultimate tensile load is the maximum amount of tensile force that can be applied along the bolts axis before failure, or fracture. where: α v is a coefficient that takes values α v = 0.6 for bolt classes 4.6, 5.6, 8.8 or α v = 0.5 for bolt classes 4.8, 5.8, 6.8 and 10.9. Each Bolt withstands a shear Force F s = F v / (Number of bolts) The resulting shear bolt stress τ n = F s /A The identification of high-strength structural bolt and nut assemblies can be readily made from the bolt head and nut markings (see Ref. 2）For stripper bolts and others which are subjected to tensile impact loads, the selection is made based on the fatigue strength. K Factor: K Factor is a torque coefficient between bolt and receptacle. Anchor Bolt Shear Strength Chart - Anchor bolt load capacities Anchor bolt strength chart bpm select the premier building: pin. • The high-strength structural (Property Class 8.8) bolt. Bolt Type. Further Reading. For bolts, the minimum tensile stress is the maximum amount of tensile stress that can be applied before failure, or fracture. English bolts have radial lines on their head to identify the grade, or strength class. The material properties of metric bolts are not exactly equal to the imperial ASTM with the same designation as there is as much as a 0.5% difference between 120 or 150 ksi used in the imperial ASTMs and the 830 or 1035 MPa used in the metric ones. Provides users with a web-based approach to calculating capacities for single bolts, nails, lag screws and wood screws per the 2015 NDS. Shear strength of alloy steel is approximately 60% of its ultimate tensile strength. The beam calculator is a great tool to quickly validate forces in beams. The beam calculator uses these equations to generate bending moment, shear force, slope and defelction diagrams. This 3-PDH course can be used to calculate the: shear, bending, and torsion strength of many types of bolted joints. Program to calculate the thread stripping strength, shear strength of the thread in tapped holes, minimum thread engagement. The second number is = 1/100. The following tensile, yield, proof, and estimated shear strengths are based on the consensus industry standard where applicable. You will find further reading on this subject in reference publications (2 & 3) Head Markings Metric Bolt Class Mechanical Properties Proof Load (MPa) Min Yield (MPa) Min Tensile Strength (MPa) Class 8.8 Medium carbon steel, quenched and tempered 580-600 640-660 800-830 Class 10.9 Alloy Steel, quenched and tempered 830 940 1040 Class 12.9 Alloy Steel, quenched and tempered 970 1100 1220 A2 Stainless Also called 18-8 or type 304 stainless steel* N/A 210 Min. To determine the force required to strip the threads, multiply the shear strength by the cross sectional area being sheared. Calculator The screw thread strength calculator contains a comprehensive database of basic dimensions for metric and Imperial standard engineering screw threads including BA, UN, UNEF, UNF, UNC, UNS, BSW & BSF, and calculates strengths and torque rates for the thread you select based upon your input data for material strength and friction coefficient .
