Recommended bolt torques. Both shear and tension are transferred through anchor bolts to resist design forces such as uplift due to wind at the top of a column or wall or vertical gravity loads on ledgers supporting joists or trusses (see Figure 1). For utmost rigidity, strength, and service, each type of fastening requires joint designs adapted to the strength properties of wood along and across the grain and to dimensional changes that may occur with changes in moisture content. The function of anchor bolts is to transfer loads to the masonry from attachments such as ledgers, sills, and bearing plates. The shear capacity of the bolt is given by . It contains two types of quenched and tempered steel heavy hex structural bolts: Type 1: medium carbon, carbon boron, or medium carbon alloy steel, Type 3: weathering steel. to know ultimate shear strength of bolt. Shear loads and tensile loads are the primary forces acting on a threaded fastener. The area of a 3/4" bolt is 285 mm 2 (Table 3-2) and the ultimate strength is 825 MPa. Where: p t is the tension strength of the bolt. Bolt Safe Working Loads (lbs) Safe tensile load at 6,000 psi load; safe shear strength at 7500 psi load) Note: These values seems awfully low to me. In other words, it's approximately 60% of the tensile strength. The following table of hex bolt head dimensions was adapted from ASME B18.6.3, Table 29, "Dimensions of Plain (Unslotted) and Slotted Regular and Large Hex Head Screws." The shear strength of a bolt is a measurement of the minimum amount of force needed to break the bolt into two pieces.
