Our fasteners are commonly used in:
- Power plant construction – including HRSG (heat recovery steam generators), STG (steam turbine generators), and CTG (combustion turbine generators) equipment foundations
- Transmission and distribution structures – including poles, towers, and substation equipment
- Industrial energy systems – pipe supports, cooling towers, boiler foundations, transformers
- Facility upgrades and retrofits – replacement anchor bolts and custom hardware for existing plants
With decades of experience, we provide job-specific custom bolts manufactured to exact project requirements, ensuring long-term reliability in demanding environments.
At Portland Bolt, we manufacture and distribute anchor bolts and specialty hardware engineered for the demands of energy facilities. With forging, threading, plate fabrication, and galvanizing performed in-house, we maintain control of our manufactured fasteners at every stage.
Our fasteners support structural alignment, reliable load transfer, and long-term performance across generation, transmission, and industrial energy projects – helping utilities and contractors keep critical infrastructure on schedule.
Domestically manufactured materials, imported and domestic stock, dependable lead times, and complete certification packages ensure every order meets project requirements and supports utility, EPC, and regulatory compliance.
When quality matters before the first pour and reliability matters long after commissioning, the power and energy industry relies on Portland Bolt.
Built to fit. Built to last.
Common Products for Power and Energy Infrastructure

Square Head Bolts »
Square head machine bolts are commonly used in pole line construction to attach crossarms, brackets, and other hardware to wooden utility poles.

Hex Bolts »
Hex bolts are one of the most widely used construction fasteners in power and industrial settings. Portland Bolt manufactures hex head bolts up to 2-1/2″ diameter in a variety of ASTM specifications.

Structural Bolts »
Heavy hex structural bolts (ASTM A325, A490) from 1/2″ to 1-1/2″ diameter are commonly used in steel erection and structural framing throughout power generating facilities.

Anchor Rods »
Available in numerous configurations, headed, welded, hooked, or straight with plate washers, anchor rods are manufactured in both standard and specialty grades to meet project-specific foundation requirements.

Tie Rod Assemblies
Tie rods provide bracing for heavy steel or timber structures. Assemblies may include turnbuckles, clevises, or custom hardware designed to handle high loads and thermal movement often present in energy facilities.

Plates »
Portland Bolt fabricates plates and angle assemblies used as anchor bolt templates, bearing plates, and custom welded configurations. Our plasma table fabricates plates up to 1-1/2″ thick.
Why Power and Energy Contractors Choose Portland Bolt
Fasteners Built for Critical Infrastructure
Our products are manufactured to meet the performance demands of power generation, transmission, distribution, and industrial energy facilities, including high loads, vibration, and long-term environmental exposure.

Vertically Integrated Manufacturing for Reliable Lead Times
In-house galvanizing, threading, heading, CNC machining, and plate fabrication allow us to control production from start to finish and avoid delays associated with outside processors.

Complete Certification and Traceability
Portland Bolt provides full documentation including mill test reports, mechanical testing, galvanizing records, and dimensional verification. This supports EPC (Engineering, Procurement, and Construction) firms, utilities, and government agencies with strict compliance requirements.
Extensive Material Inventory for Large and Complex Projects
With 12 grades of round bar in 23 diameters, we can quickly supply large-diameter and anchor bolts used in HRSG, STG, CTG, cooling towers, transformers, and major foundations.
Engineering and Specification Support
Our experienced team works from supplied drawings and specifications to manufacture fasteners to the required dimensions, grades, coatings, and assembly details for power and energy projects.
Portland Bolt Fasteners Guide
for Critical Energy Infrastructure
Power and energy projects depend on fasteners that meet demanding structural, environmental, and documentation requirements. The Portland Bolt Fasteners Guide gives utilities, EPC firms, contractors, and project teams a practical reference for specifying and sourcing critical hardware with confidence. It covers common fastener types, material and coating considerations, configuration details, and key questions to address early when planning foundations, equipment anchoring, transmission structures, substations, and industrial energy systems.
