It features a 7\/8-9 UNC thread form and measures 3-1\/2 inches under the head. Built to ASTM A490 and ASTM F2280 standards, this bolt delivers the high clamp load required for structural steel assemblies. Each package includes a matching nut and washer, allowing the installer to complete the bolt group without sourcing additional components. The uncoated, bright finish leaves the fastener ready for field installation as-received.\u003c\/p\u003e\n\u003cp\u003eThis tension control bolt is used in structural steel framing, beam-to-column connections, and moment frame assemblies common in commercial and industrial construction. The splined shear-type end of a TC bolt assembly allows installation with a standard TC impact wrench, which shears the spline tip at the correct tension. Ironworkers and structural steel erectors are the primary installers. Each package contains 5 bolt assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC thread size for standard structural bolt hole patterns\u003c\/li\u003e\n  \u003cli\u003e3-1\/2 inch length under head accommodates common steel stack thicknesses\u003c\/li\u003e\n  \u003cli\u003eASTM A490 and ASTM F2280 certified for structural high-strength applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating removal required before inspection\u003c\/li\u003e\n  \u003cli\u003eIncludes nut and washer — complete bolt group in one package\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 5 suits small repairs and single-connection jobs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in structural steel connections requiring ASTM A490 high-strength tension control bolt assemblies with 7\/8-9 UNC thread. Consult project drawings and the engineer of record to confirm bolt length and grade specifications before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified ironworkers using a calibrated TC impact wrench; the splined tip shears when the bolt reaches the required pretension, providing a visual confirmation of proper installation. Follow AISC and RCSC specification requirements for snug-tight sequencing and pretensioning procedures. Do not reuse tension control bolts once the spline tip has been sheared. Store bolt assemblies in a dry location and protect from corrosion prior to installation.\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: 3-1\/2 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 Standard\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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161613\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: TCI40870350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691081957682,"sku":"TCI40870350","price":81.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03e91b7968d1d2261f0e169883faf684.jpg?v=1788280114","url":"https:\/\/voomisupply.com\/products\/value-collection-tci40870350-tension-control-bolt-7-8-9","provider":"Voomi Supply","version":"1.0","type":"link"}
