Structural Steel Types and Grades . There is not just one type of structural steel. There exist various different shapes and grades, depending on the needs for that specific application. Structural steels are classified by the shape of their cross-sections, such as the most frequently used I, T, C shapes (2). Besides their shape, the grade of
ASTM A325 Bolts Dimensions Chart, Strength, Grade A325 ASTM A325 Bolt Dimensions Chart, Sizes, Strength. ASTM A325 bolts are one of the most commonly used fasteners, usually used for structural steel connections in heavy steel structures. It contains two types of quenched and tempered steel heavy hex structural bolts:Type 1:medium carbon, carbon boron, or medium carbon alloy steel,

Turn-Of-NutAlternative Design BoltsWasher ControlCalibrated Wrench MethodThis method involves tightening the fastener to a low initial "snug tight" condition and then applying a prescribed amount of turn to develop the required preload. The actual preload will depend on how far the nut is turned as well as how much preload was established prior to the turning. 1. Snug the joint to bring the assembly into firm contact. Apply a few impacts with impact wrench until solid sound or apply full effort with a spud wrench. 2. Inspect the joint to verify "snug tight". 3.
