THREADLINE PRODUCTS, INC.

What THREADLINE PRODUCTS, INC. does

Threadline Products, Inc. is a Charlotte, North Carolina-based custom metal fabrication company specializing in threaded fasteners, anchor bolts, structural hardware, and fabricated steel components serving the commercial and infrastructure construction markets. Founded in 1984, Threadline manufactures and distributes anchor bolts including bent configurations, all-thread rods, double-ended studs, and headed studs, alongside mechanical and adhesive anchors from DeWalt and Simpson Strong-Tie, structural bolts to ASTM A325, A490, and A307 specifications, and custom fabricated items such as plate embeds, angle embeds, sag rods, and tie rod assemblies. Production relies on certified welding and in-house roll threading capabilities, with steel drawn from U.S. domestic sources and the option to source imported hardware to specification.

The company operates a direct, quote-driven sales model: customers request a quote online via Build A Quote, by email, or by phone, and revenue is generated through one-time project sales of standard catalog fasteners at list pricing and custom fabricated products priced per quote based on material grade, finish, dimensions, and complexity. Threadline serves commercial and industrial construction, government and infrastructure customers including state DOTs, OEMs, precast and metal building contractors, and large industrial distributors, with shipping reach across the Southeast, East Coast, and Mid-Atlantic and 1-3 day nationwide fulfillment including same-day or next-day delivery to twelve or more states.

The company has scaled through two inorganic moves: the February 2022 acquisition of Atlantic Bolt, Inc. and the December 2024 acquisition of the Atlantic Fastener / Würth Greensboro, NC facility. A new 27,635 sq ft Charlotte headquarters opened in January 2024, consolidating Threadline and Atlantic Bolt under one roof. Threadline remains privately held and family-controlled, co-owned by Jenny Miller (President and CEO) and Josh Miller (VP and Co-Owner), with no institutional investors, parent entity, or public reporting obligations.

Direct peers

• Monroe Engineering: Custom fastener manufacturer and industrial supply distributor offering specialty bolts, anchors, and threaded products. Comparable in serving OEMs and construction customers with custom-spec orders.
• Simpson Strong-Tie: Industry-leading manufacturer of structural connectors, anchor bolts, and fasteners for construction. Closest direct competitor given Threadline's resale of Simpson mechanical and adhesive anchors and overlap in DOT-compliant structural fastening.
• Haydon Bolts: Manufacturer of custom and standard anchor bolts, structural bolts, and threaded fasteners serving bridge, highway, and commercial construction. Closely comparable in DOT/AASHTO-compliance focus and custom-bending capabilities.
• Portland Bolt: Custom manufacturer of anchor bolts, structural bolts, and threaded rod serving construction and infrastructure. Highly comparable business model built around custom fabrication, fast lead times, and engineer-spec orders.
• Baco Enterprises: Manufacturer of anchor bolts, structural bolts, and fabricated steel hardware for construction and infrastructure. Closely comparable niche competitor focused on DOT-compliant and custom-spec fasteners.
• Allied Bolt: Manufacturer and distributor of construction fasteners including anchor bolts, mechanical anchors, and structural hardware. Directly comparable product portfolio and customer base of contractors and steel fabricators.
• Chicago Hardware & Fixture: Domestic manufacturer of bolts, threaded rod, and structural hardware for industrial and construction applications. Comparable in operating as a U.S.-based custom fabrication shop with regional distribution and engineering-spec work.

Broad incumbents

• Fastenal: Largest U.S. industrial fastener and supply distributor with national branch network and OEM/contractor customer base. Competes on price, SKU breadth, and delivery density that Threadline's two-facility footprint cannot match.
• Würth Industry: Global fastener and assembly solutions provider serving industrial and construction customers with broad catalog and vendor-managed inventory. Particularly relevant given Threadline's recent asset acquisition of the former Würth/Atlantic Fastener Greensboro facility.
• Hilti: Global manufacturer of tools, anchors, and fastening systems for construction professionals. Competes in mechanical and adhesive anchoring segments where Threadline resells Hilti-adjacent DeWalt and Simpson lines.
