Portland Bolt & Manufacturing

What Portland Bolt & Manufacturing does

Portland Bolt & Manufacturing Co., LLC is a U.S. specialty fastener manufacturer founded in 1912 in Portland, Oregon. The company designs, forges, threads, fabricates, and hot-dip galvanizes nonstandard anchor bolts, rods, bent bolts, nuts, washers, and related construction hardware for nonstandard specifications not typically stocked by general line fastener distributors. Its horizontal hot-forging process using National Upsetters can produce headed bolts up to 40 feet long and 2-1/2 inches in diameter, complemented by CNC lathe turning, threading, cutting, bending, and plate fabrication under one roof. Vertical integration into in-house hot-dip galvanizing is positioned as a lead-time differentiator versus competitors that outsource coatings.

The company sells via a quote-based direct sales motion staffed by experienced estimators who assist engineers, architects, contractors, and government buyers with fastener specifications; there are no stated minimum order quantities on custom orders. Customer segments span bridge and DOT infrastructure, marine construction, power and energy, light rail, mining, timber construction, OEM, and government/military applications, with explicit DOT approval and domestic manufacturing compliance as qualification requirements. Operations span a 137,000 sq ft Portland headquarters and manufacturing plant, a North Augusta, South Carolina facility acquired in 2024, a Jordan, New York distribution site, and the Bellows Falls, Vermont-based Applied Bolting Technology subsidiary acquired in April 2025; in 2024 the Portland site shipped 7.09M pounds across 10,129 orders to all 50 U.S. states, 12 Canadian provinces/territories, and 28 international markets. The business is privately held with no disclosed PE, VC, or parent company involvement, and a management team anchored by long-tenured veterans such as Greg Lindsay (with the company since 1991). Bennett Bolt Works was acquired on 2025-05-14, signaling continued inorganic expansion.

Direct peers

• Lawson Products: Public distributor of industrial fasteners, parts, and supplies to construction, industrial, and government customers across North America. Comparable in its sales-led distribution model and construction/industrial customer mix, though Lawson distributes rather than manufactures.
• Fastenal: Public industrial fastener and supply distributor and manufacturer serving construction, infrastructure, and OEM customers across North America. Directly comparable business model (sales-led, multichannel distribution, broad fastener catalog) though at vastly larger scale than Portland Bolt's specialty positioning.
• Würth Group: Global market leader in fastening and assembly materials for construction, metalworking, and automotive. Comparable in its specialization in fasteners and technical advisory services, though operating at substantially greater scale and geographic breadth than Portland Bolt.
• Hilti: Global manufacturer of tools, anchors, and fastening systems serving construction, energy, and infrastructure professionals. Directly comparable in serving engineers and contractors specifying structural anchors and fasteners, with overlapping customer segments in DOT, marine, and infrastructure projects.
• Grip-Rite (PrimeSource Brands): Brand of PrimeSource Brands specializing in fasteners, nails, and construction hardware for residential and commercial construction. Comparable in serving construction contractors with made-in-USA-positioned fasteners for structural and framing applications.
• Birmingham Fastener & Supply: US-based manufacturer and distributor of standard and custom industrial fasteners including anchor bolts, structural bolts, and threaded rod. Closely comparable in its niche specialization in nonstandard and large-diameter fasteners for construction and infrastructure.
• Allfasteners: Industrial fastener manufacturer and distributor serving construction, infrastructure, and OEM customers with anchor bolts, studs, and threaded products. Comparable in its specialty focus on construction-grade fasteners and made-in-USA positioning.
• Simpson Strong-Tie: Manufacturer of structural connectors, anchor bolts, and fasteners for construction and infrastructure applications. Highly comparable in serving structural engineers, DOTs, and contractors with engineered fastening solutions for bridges, marine, and timber construction.

Broad incumbents

• Stanley Black & Decker: Global industrial conglomerate whose fastening and construction businesses (including DEWALT, Powers fasteners) compete in the construction fastening space. A broad incumbent with overlapping adjacency rather than a direct specialty-bolt specialist.
• Illinois Tool Works (ITW): Diversified industrial manufacturer whose ITW Construction segment produces fastening systems and construction components (including Buildex, Ramset, Red Head). Operates adjacent to Portland Bolt's specialty structural fastener niche as part of a much broader industrial portfolio.
