It features a 7\/8-9 UNC thread and a 6-inch length under head, with a 1-5\/8-inch head diameter. Manufactured from A490 steel and supplied in a bright, uncoated finish, this bolt meets ASTM A490 and ASTM F2280 standards. Each package includes a nut and washer, making it ready for direct installation. It is installed using a tension control installation tool that shears the splined end when proper pretension is achieved, eliminating the need for torque wrenches on site.\u003c\/p\u003e\n\u003cp\u003eThis tension control bolt is used in structural steel connections on commercial and industrial construction projects, including beam-to-column connections, moment frames, and other bolted joints requiring controlled pretension. It is appropriate for applications governed by AISC and RCSC specifications. The included nut and washer are matched components intended for use with the supplied bolt. Licensed ironworkers and structural steel erectors are the primary installers for this fastener type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC thread for compatibility with standard structural steel connections\u003c\/li\u003e\n  \u003cli\u003e6-inch length under head suits thick connection stacks common in heavy fabrication\u003c\/li\u003e\n  \u003cli\u003eA490 high-strength steel construction meets ASTM A490 and ASTM F2280 standards\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for standard interior structural applications\u003c\/li\u003e\n  \u003cli\u003eIncludes matching nut and washer for a complete fastener assembly\u003c\/li\u003e\n  \u003cli\u003eSplined end design enables installation with a tension control tool without torque verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style structural fastener for high-strength bolted steel connections requiring ASTM A490 or ASTM F2280 compliant tension control bolts in the 7\/8-9 UNC thread size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTension control bolts must be installed by qualified ironworkers or structural steel erectors using an approved tension control installation tool. Verify that the mating steel surfaces are free of debris, excess mill scale, or coatings that are not permitted under the applicable connection specification before installation. Do not reuse tension control bolts that have had the splined end sheared, as pretension cannot be re-established. Follow AISC and RCSC bolting specifications and applicable local structural codes throughout the installation process.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: A490\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standards\u003c\/strong\u003e: ASTM A490, ASTM F2280\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Nut and Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound (per package)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TCI40870600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717091131698,"sku":"TCI40870600","price":104.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a73d476e4e94b09c07d1bfaf61a0d967.jpg?v=1788535572","url":"https:\/\/voomisupply.com\/products\/value-collection-tci40870600-tension-control-bolt-7-8-9","provider":"Voomi Supply","version":"1.0","type":"link"}
