ASTM A36 Carbon Steel Fasteners are widely used fastening components manufactured from ASTM A36 carbon structural steel for construction, structural steelwork, infrastructure, fabrication, machinery and general engineering applications. These fasteners offer a practical combination of strength, machinability, weldability and cost-effectiveness for applications where dependable mechanical fastening is required.
We manufacture and supply ASTM A36 Bolts and Nuts, ASTM A36 Threaded Rods, structural plate washers, U-bolts, eye bolts and foundation anchor bolts in different sizes, configurations and finishes. Depending on application requirements, A36 Carbon Steel Fasteners can be supplied with a plain finish or protective coatings such as hot-dip galvanizing.
What Are ASTM A36 Carbon Steel Fasteners?
ASTM A36 is a commonly specified carbon structural steel grade known for its good strength and fabrication characteristics. ASTM A36 Carbon Steel Fasteners are selected for applications requiring reliable fastening together with economical material performance.
The grade is particularly suitable for structural and general-purpose applications where extremely high tensile strength or specialized alloy performance is not required. Fasteners can be manufactured in various forms, including hex bolts, nuts, threaded rods, washers, anchor bolts, U-bolts and eye bolts.
ASTM A36 Carbon Steel Fasteners are fastening components made from ASTM A36 carbon structural steel and are commonly used in construction, structural steelwork, machinery, fabrication and infrastructure applications. They are available in plain and coated finishes and include bolts, nuts, threaded rods, washers, anchor bolts, U-bolts and eye bolts.

ASTM A36 Fasteners Product Range
We offer a broad range of A36 Carbon Steel Fasteners for structural and industrial applications.
➤ ASTM A36 Bolts and Nuts
ASTM A36 Bolts and Nuts are used to mechanically join structural members, fabricated components, machinery parts and general engineering assemblies. Depending on the application, we can supply hex bolts, heavy hex bolts, structural bolts and matching nuts in different dimensions and configurations.
➤ ASTM A36 Threaded Rod
ASTM A36 Threaded Rod provides continuous external threading for applications requiring adjustable fastening, suspension, anchoring or component assembly. Threaded rods can be supplied in different diameters, lengths and thread configurations.
➤ ASTM A36 Structural Plate Washers
ASTM A36 Structural Plate Washers are designed to distribute the applied load over a larger surface area. They are particularly useful with structural connections, foundation assemblies and anchoring applications where standard washers may not provide sufficient bearing area.
➤ ASTM A36 U-Bolts & Eye Bolts
ASTM A36 U-Bolts & Eye Bolts are available for specialized fastening and support applications. U-bolts are commonly used for pipe, tube and structural support, while eye bolts provide a convenient lifting, anchoring or attachment point where the design permits.
➤ Plain Finish A36 Foundation Anchor Bolts
Plain Finish A36 Foundation Anchor Bolts are used to secure structural columns, equipment bases, steel structures and other components to concrete foundations. They can be supplied in straight, bent or application-specific configurations according to project requirements.
ASTM A36 Fastener Finishes
The surface finish of a fastener influences its resistance to corrosion and its suitability for the installation environment.
- Plain Finish: Plain or untreated A36 Carbon Steel Fasteners are suitable for controlled indoor environments or applications where additional corrosion protection is not required.
- Hot Dip Galvanized: Hot Dip Galvanized ASTM A36 Fasteners have a zinc coating that provides enhanced protection against atmospheric corrosion. They are commonly considered for outdoor structures, infrastructure, construction projects and other environments exposed to moisture.
Other coating or finishing requirements may be available according to project specifications.
