The shear strength of a grade 8 bolt is 90,000 psi, assuming the bolt is between 1/4 inch to 1 inch. Shear strength is typically estimated to be 60 percent of tensile strength. The tensile strength of a grade 8 bolt is at least 150,000 psi.
Continue ReadingAll grade 8 bolts have the same tensile strength per square inch. Thus, the larger the bolt, the stronger the tensile strength of the bolt. Shear strength must be calculated, because the American Society for Testing and Materials does not require shear strength values to be published. To calculate tensile strength of a bolt, the tensile stress area should be multiplied by 150,000 psi.

Full Answer >Converting from pounds per square inch to pascals is a simple unit conversion problem that can be solved in a short amount of time with pencil and paper or calculator. Simply multiply the known information by the conversion factor, cancel the units and solve the equation.
Full Answer >Concrete that is designated as 3,000 pounds of pressure per square inch is commonly used for residential driveways and basement slabs. This concrete is not considered to be high strength but is poured to carry a compressive strength of 3,000 pounds of pressure per square inch after 28 days.
Full Answer >Self-locking nuts use either a pre-installed plastic insert or a chemical substance applied to the threads that, when initially tightened down, spreads in between the threads to create a more stable adhesive bond than the metal-to-metal connection of an ordinary nut and bolt. Locking nuts keep a threaded nut and bolt assembly from coming loose due to vibration and loss of torque required to maintain structural integrity.
