Privacy Policy | As a comparison, the ASTM A325 bolt is roughly equivalent to the SAE grade 5. I'm not a metalurgist or engineer, but as I understand it, the reduced ductility means it's more brittle. Two principles influence the correct clamping pressure for each bolt, known as clamp load. The first is bolt diameter. The second is the class of the bolt, defined by the bolts tensile strength, which in turn is determined by the material of construction. This information is derived from data here. Here is how the bolt strength is specified: Tensile Strength: The maximum load in tension which a material can withstand before fracturing.
