Complete Your Structural Bolt and Anchor Bolt Assembly

One Source for the Whole Assembly

A hardened washer is one component of a complete structural bolting assembly. Portland Bolt manufactures and supplies the bolts, anchor bolts, nuts, and washers that make up these assemblies, so customers can source multiple components from one manufacturer.

A structural bolted connection rarely uses a washer on its own. The washer works together with a matched bolt and nut, and often with Applied Bolting Technology Squirter DTI Washers, to develop and verify the specified pretension. When those components come from a single manufacturer, they can be coordinated for compatible grade, finish, and material type, and the documentation for the whole assembly stays together. That coordination reduces the risk of a mismatch between a bolt, its nut, and its washer, and it simplifies procurement for the project.

• ASTM F3125 Grade A325 Structural Bolts — high-strength heavy hex structural bolts formerly designated A325.

• ASTM F3125 Grade A490 Structural Bolts — high-strength structural bolts formerly designated A490.

• ASTM F3125 Grade 144 Structural Bolts — high-strength structural bolts.

• ASTM F1554 Anchor Bolts — Grades 36, 55, and 105 for column bases and equipment.

• Heavy Hex Nuts — to specifications including ASTM A563 and A194.

• Squirter DTI Washers, Applied Bolting Technology — direct tension indicators for verifying tension in bolted connections.

Complete Structural Assemblies

Portland Bolt is most competitive when manufacturing the complete bolting assembly for a project. Combining bolts, anchor bolts, nuts, and hardened washers into one package lets the components be coordinated together from a single source.

Sourcing the assembly as a package also keeps the certifications and material documentation for the bolts, nuts, and washers together, which is often a requirement on structural and infrastructure projects. It reduces the coordination burden of matching parts from different suppliers and helps ensure the washer, the bolt, and the nut are compatible in grade, material type, and finish for the connection they serve.
