Unlike tensile and yield strengths, there are no published shear strength values or requirements for ASTM specifications. Also, shear strength is approximately 60% of the minimum tensile strength. It is important to understand that some imported fastener are typically ungraded. Since they are not manufactured to any specific grade, it is impossible to determine any strength characteristics for
. bolts unless you have them strength tested in a laboratory. For more info click on http://www.portlandbolt.com/faqs/bolt-shear-strength-considerations.
