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...

Tensile Strengthis the maximum load in tension (pulling apart) that a material can withstand before breaking or fracturing. 1MPa = 145 pounds/inch² Approximate Equivalent Chart for Metric and English (USS/SAE) Bolts
Tensile stress and Hooke's Law. Elongation Bolt stretching according Hook's Law can be calculated as dl = F L / E A (1) where dl = change in length of bolt (inches, m) F = applied tensile load (lb, N) Leff = effective length of bolt where tensile strength is applied (inches,...
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...
Because of the larger tensile stress areas, they have high tension strength. However, a longer engagement is required for fine thread applications than for coarse series threads to prevent stripping. 8– Thread Series (8UN) is the specified thread forming method for several ASTM standards ...
