The proof load itself is usually 85% to 95% of a bolt’s yield strength, but the clamp load is significant because it is what ultimately provides the clamping pressure.

| Stripper bolt material: 4137 33～38 HRC, strength class 10.9.） From the table at right, for a strength class of 10.9 and a maximum allowable (psi) s tensile = Ultimate Yield Strength (lbs) t min = Minimum tensile strength of the bolt grade, ASTM, SAE, etc. Ultimate strength can be defined for liquids as well as solids under certain conditions. The strength data is assumed to be accurate at room temperature only and for applications that expose the fastener to extreme temperatures or for other questions related to the content below, contact the Fastenal Engineering & Design Support at engineer@fastenal.com. Determine whether the bolt is safe or unsafe in both shear and tensile stresses. The tensile load a fastener can withstand is determined by the formula P = St x As. I accept the terms and conditions set forth above. the anchor bolt breaks D L Bond Strength Epoxy to Steel The bond of grout to the steel anchor bolt can be calculated using 1600 psi as the Bond Strength of epoxy to steel.
1. T = wrench torque (Nm, lb f ft) K = constant that depends on the bolt material and size .
Tensile strength is the maximum tension-applied load the fastener can support prior to fracture. Changing this settings will alter the functionality of this site and your user experience could be diminished. Use Ubs = 1.0. var proof = null;
Shear is not part of any industry standard and the values presented below are estimations based on 60% of the ultimate tensile strengths.
There exists an often quoted myth, that Grade 5 bolts are better in shear than Grade 8 since they will bend before breaking. Below given the ultimate tensile strength formula to calculate the ultimate strength … The tensile strength of a grade 8 bolt is 150,000 pounds per square inch. Preloaded Bolts : Refer to page Preloading if (value == 0) value = "N/A";
Thus, for the bolt of property class 8,8 in the above example a nut of property class 8 is required. The recommended value in EN1993-1-8 is γM2 = 1.25. var tensile = 60000;
