ASTM A325 Bolts
ASTM A325 Bolts are heavy hex bolts made of heat-treated steel. Typically, they are short in total length and are used to attach structural steel to concrete. The bolts meet the ASTM specification for structural steel ties and bolts in both metric and imperial sizes. They are unique in their chemical and mechanical specifications, including the configuration tolerance. Listed below are some applications for ASTM A325 Bolts.
For large steel structures, A325 bolts are typically recommended by engineers. These bolts have high strength steel, high pretension, and high resistance to fatigue. They are used in bridges, heavy machinery structures, and high-pressure equipment connections. The A325 bolt is widely used in the metal structure of cranes. A325 bolts are ideal for these applications. They can be used in heavy construction projects and OEM projects and can be found in heavy machinery parts.
ASTM A325 bolts are available in various sizes and are often called "heavy hex" bolts. A325 bolts range in diameter from half an inch to one-and-a-half inches. They have minimum tensile strengths of 120/105 ksi. The bolts are marked with their grade and manufacturer's identification marks. The grade of the A325 bolt depends on its chemical and mechanical properties. Grade 8 bolts have six radial lines.
Uses of ASTM A325 Bolts
The A325 anchor bolt standard is a standard for structural bolts. Its strength is governed by the material used to manufacture the bolt. The bolts are available in metric and imperial sizes and come with various markings. The bolts' tensile strength is 830 MPa and their yield strength is 660 MPa. These values are almost three times greater than those of ordinary stainless steel. The bolts are made from medium-carbon steel, which is used to develop the required mechanical properties.
There are several different types of ASTM A325 bolts. Type 2 is withdrawn from use while type 3 is obsolete. Type 2 and 3 anchor bolts are made of weathering steels, which do not need coating because the patina is a barrier against corrosion. Type 1 anchor bolts, on the other hand, are made of medium carbon steel and are used for structural connections. They can be made with various types of coating.
The use of A325 bolts is widespread in heavy construction because they are known for their durability and strength. In fact, they are the most common type of bolt used in heavy construction. The Research Council on Structural Connections (RCSC) sets the A325 bolt specification. As a result, the Federal Highway Administration recommends that the fasteners be used in heavy construction.
