Structural Bolts - Material Options

South Coast Fasteners stocks structural bolts in a range of high-performance materials chosen for their strength ratings, mechanical consistency, and ability to meet engineering requirements in the field.

A307 Grade B

A strong option for structural connections where extreme tension is not the primary concern. These bolts are commonly used with cast iron flanges, piping supports, and connections where high loads are not expected. A307 Grade B offers simplicity, reliability, and a trusted spec for lighter structural applications.

A325

This is one of the most specified structural bolt grades for steel-to-steel assemblies in buildings, bridges, and heavy infrastructure. A325 bolts provide excellent strength and are designed for tensioned or snug-tight joints. They are widely used across commercial and industrial construction and are often called out by engineers on structural plans.

A325 Type 1

Made from medium carbon steel, A325 Type 1 bolts meet the same strength performance as standard A325 but with material traceability that is critical for many inspection-driven projects. These are preferred in structural steel assemblies where consistency and documentation are essential, such as in schools, stadiums, or public infrastructure.

A490

A490 bolts offer greater tensile strength than A325 and are used where load demands exceed standard bolt capabilities. These bolts are common in seismic applications, cantilevered systems, and structures exposed to dynamic forces. Because of their high strength and hardness, they require careful installation and torque control, but they deliver excellent holding power in critical zones.

A490 Type 1

This alloy steel version of the A490 bolt provides the same elevated strength with added material designation for engineering and compliance documentation. These bolts are used in load-sensitive environments like tower cranes, steel frame expansions, or retrofit bridge connections where reliability and traceability both matter.

Grade A193 B7 Steel

This grade is typically used for threaded assemblies in structural environments where temperature, pressure, or chemical exposure are a concern. A193 B7 bolts are heat-treated for extra strength and are often found in anchor rod systems, structural embed plates, and engineered components that require high performance under stress.

Structural Bolts - Available Finishes

South Coast Fasteners offers structural bolts with finish options selected to handle the environmental conditions and corrosion exposure of long-term structural installations.

Hot Dip Galvanized

This zinc-based coating offers outstanding corrosion protection for exterior and exposed structures. Commonly used in bridges, outdoor frames, and marine builds, hot dip galvanized bolts form a durable shield that helps prevent rust, surface breakdown, and failure over time. They are often required for projects in coastal or high-moisture regions.

Plain

Plain finish bolts come without any added coating and are generally used in dry indoor environments or in applications where the bolts will be painted or treated on-site. These are simple, cost-effective, and ideal when you need raw steel that is ready for custom processing or immediate installation inside climate-controlled spaces.
