UNSPSC 31161613: Tension bolts

UNSPSC 31161613 Tension bolts is a Commodity code that state and local governments procure primarily as components within larger construction, infrastructure, and equipment assembly projects rather than as standalone fastener orders. Recent solicitations show tension bolts appearing as specification items embedded in guardrail systems, water treatment facility modifications, transmission steel pole structures, and law enforcement equipment frameworks — they are called out in bills of materials and technical specifications but rarely as the primary procurement focus. Issuing bodies span city engineering departments (Sandy Springs, Georgia), utility authorities (Kissimmee Utility Authority, Florida), state procurement offices (State of Georgia), and cooperative purchasing vehicles serving multi-jurisdictional public sector buyers (Sourcewell on behalf of Washington state counties and national participating entities). The code sees activity from municipal public works departments, special-purpose utility authorities, and state-level construction material procurement offices rather than consolidated repeat purchasing under a single jurisdictional buyer.

Recent opportunities show tension bolts specified across Georgia, Florida, and Washington state. The City of Sandy Springs posted an ITB on February 19, 2026 (due March 20, 2026) for guardrail maintenance and repair services that called for tension bolts as part of Type W and Type T beam guardrail anchorage and terminal hardware systems. The City of Lavonia, Georgia solicited construction services on April 24, 2026 (due May 26, 2026) for water treatment plant improvements requiring tension bolts in structural connections across the flash mixer, settling basins, and filtration unit renovations. The Kissimmee Utility Authority in Florida issued an IFB for transmission tubular steel poles calling for anchor bolts and structural components with tension specifications. The code shows activity across transportation, water infrastructure, and utility construction sectors, but tension bolts themselves remain embedded within broader structural or mechanical assembly specifications rather than standing as discrete procurement line items. Vendors pursuing this code should expect to bid them as components within equipment or construction contracts rather than as primary products, and should focus on specification compliance, delivery timing tied to project schedules, and integration with larger fabrication or assembly workflows.
