About

About Portland Bolt Portland Bolt & Manufacturing Company is a leading domestic manufacturer and supplier of custom anchor bolts, structural fasteners, and connection hardware supporting the heavy timber and mass timber construction industries. As mass timber projects continue to grow in size and complexity, they demand fastening solutions that are engineered, precise, and often nonstandard. Portland Bolt specializes in project-specific hardware for CLT, glulam, and hybrid timber systems, including large-diameter anchor rods, custom threading, nonstandard lengths, plate fabrication, and ASTM-compliant fasteners manufactured in the USA. With four locations across the country totaling more than 270,000 square feet of manufacturing and distribution space, plus in-house hot-dip galvanizing, we provide the scale, redundancy, and geographic reach mass timber projects require. Our coast-to-coast footprint allows us to support tight schedules, large connection packages, and phased deliveries while coordinating closely with engineers, fabricators, and installers. From early design collaboration through final delivery, Portland Bolt brings the experience, flexibility, and capacity needed to support modern mass timber construction—where connection performance, reliability, and timing are critical to success.
