What Applied Bolting Technology Products, Inc. does

Applied Bolting Technology Products, Inc. (operating as Applied Bolting Technology LLC) is a Bellows Falls, Vermont-based manufacturer founded in 1994 that produces Squirter® Direct Tension Indicators (DTIs) with its patented DuraSquirt® Formula. The DTIs are heat-treated washer-style devices that provide visual verification of proper bolt tension in structural steel connections, eliminating the need for feeler gauges. The company is the only U.S. manufacturer dedicated exclusively to heat-treated DTIs and produces products compliant with ASTM F959, BS 7644, EN 14399, AASHTO, AISC, and RCSC specifications, available in imperial sizes from 1/2" to 1-1/2" and metric sizes M12 to M36 across galvanized, Type 3, and plain finishes.

The company's primary customers are structural steel contractors, EPC firms including Bechtel, Fluor, Worley, Kiewit, and Burns & McDonnell, bridge fabricators such as Stupp Bridge, and infrastructure project teams. Revenue is generated predominantly through direct B2B sales and a network of 48 authorized distributors across North America, South America, Asia-Pacific, the Middle East, and Europe, with Portland Bolt serving as preferred distributor. Pricing is quote-based on volume and specifications with multi-year contract cadences. Secondary revenue comes from training services including Lunch and Learn clinics and webinars supporting PDH certification for structural engineers, ironworker apprenticeship programs (Locals 68, 721, 584), and EPC project teams.

The business operates an enterprise field-sales motion combining dedicated technical support, distributor enablement, and event-driven training programs to drive specification-level adoption with engineers. Since 2025, the company has operated as part of the Portland Bolt family of companies, and maintains ISO 9001:2015 certification (expiring November 30, 2028). Manufacturing and distribution are conducted from a single Vermont facility supported by a 15,000-cubic-foot on-site warehouse with reported headcount of 11-50 employees.

It addresses adjacent parts of the structural bolting quality-control workflow and shares the same contractor and inspector customer base.

Direct peers

• LeJeune Bolt Company: LeJeune Bolt Company produces large-diameter structural bolts, tie rods, and fasteners for bridges, buildings, and heavy infrastructure. It serves the same specifier and contractor audience and competes on structural bolting projects.
• Chicago Hardware & Iron: Chicago Hardware & Iron produces structural and industrial fasteners including heavy hex bolts and related products for construction and infrastructure. It competes in the same high-strength structural fastener category used in conjunction with DTI washers.
• Midwest Structural Products: Midwest Structural Products supplies structural bolting products and accessories used in steel construction. It targets similar contractors and EPC customers on bridge and building projects where DTI washers are specified.
• Haydon Bolts: Haydon Bolts manufactures structural bolts, anchor bolts, and related fasteners used in bridge, building, and infrastructure construction. It addresses the same structural bolting specification ecosystem as Applied Bolting Technology.
• Portland Bolt: Portland Bolt is the parent company and preferred distributor of Applied Bolting Technology and a manufacturer of structural bolts and related fastening products serving the same construction, bridge, and infrastructure end markets. The two share customer overlap and distribution, making Portland Bolt the closest direct comparator and channel partner.
