ASTM A325 Bolt Strength. ASTM A325 bolt strength are summarized in the table bellow inluding tensile strength, yield strength and hardness, etc. Notes:The stress area is calculated as follows:A s = 0.7854 [D- (0.9743/n)] A s = stress area, in 2, D = nominal bolt size, and. n = threads per inch. Fastener Grade, Material, Strength ComparisonYield strength is stress at which a permanent set of 0.2% of gage length occurs. After manufacturing, steel fasteners should be electroplated, zinc with a yellow chromate conversion per ISO 4042, Examples of hardened fasteners are steel bolts - US Grade 8 (Metric property class 10.9), hardened steel washers, spring washers, etc.
Gr 8 bolt capability in yield (stretch) = 130,000 lbs / in2 x .03349 in2 = 4354 lbs minimum High tensile Grade 8 bolt capability in tension (failure) = 150,000 lbs / in2 x .03349 in2 = 5024 lbs minimum Grade 8 hex bolts have 6 marks on the head. tensile strength is 150,000 lbs per square inch ultimate shear strength Grades of Bolts - The Home DepotThere are several grades of bolts but the three common grades for SAE are 2, 5 and 8. The common class (grades) for metric are 5.8, 8.8, 10.9 and 12.9. Each grade has a specific bolt strength. No matter the system used to grade the bolts, the higher the number means the stronger the bolt.

Dec 14, 2019 · EN 10025 S355 Steel. S355 steel is a European standard structural steel grade, according to EN 10025-2:2004, material S355 is divided into 4 main quality grades:S355K2 (1.0596). The properties of structural steel S355 is better than steel S235 and S275 in yield strength and tensile strength.
