The installation methods that are required to be used when installing structural bolts (A325 and A490) would ensure the bolts are installed to a minimum of 70% of the minimum tensile strength. This would provide greater resistance to vibration that any of the standard lock nuts and lock washers. ASTM A325 and A490 only allow the use of ASTM F436 flat washers or ASTM F959 DTI washers.
