Take the minimum yield in psi of the ASTM grade (see ourStrength Requirements by Grade Chartfor this value), multiplied by the stress area of the specific diameter (see ourThread Pitch Chart). This formula will give you the ultimate yield strength of that size and grade of bolt. Example:W...
Thread Size Chart Thread fit categorizes the tolerances between the peaks and valleys (crests and roots) of mating threaded hardware. In metric descriptions, thread fit is classified by a number and letter system; lower numbers indicate threads with higher precision and letters indicate tolerance pos...
