This fastener features a 1-8 UNC thread, a 2.5-inch length under head, and a 1.875-inch head diameter. Manufactured from A325 steel with a bright uncoated finish, it meets ASTM A325 and ASTM F1852 standards. Each unit ships as a complete assembly including a nut and washer, making it ready for direct installation without sourcing additional components. Licensed ironworkers and structural steel contractors are the primary installers of this fastener type.\u003c\/p\u003e\n\u003cp\u003eThis tension control bolt is used in structural steel connections in commercial and industrial construction, steel bridges, and heavy fabrication projects. The splined shear-type end allows for installation with a TC wrench, eliminating the need for torque measurement and ensuring consistent pretension. It is suited for applications where AISC and RCSC specification compliance is required for bolted structural joints.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC thread for standard structural bolt hole patterns\u003c\/li\u003e\n  \u003cli\u003e2.5-inch length under head accommodates typical multi-ply steel connections\u003c\/li\u003e\n  \u003cli\u003eA325 steel construction meets ASTM A325 and ASTM F1852 requirements\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for use in dry or protected structural environments\u003c\/li\u003e\n  \u003cli\u003eIncludes nut and washer for complete single-assembly installation\u003c\/li\u003e\n  \u003cli\u003eSplined shear-type design enables consistent pretension without torque measurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style structural fastener for use in standard 1-inch diameter bolt holes in ASTM A325-compliant bolted steel connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified ironworkers or structural steel contractors in accordance with RCSC Specification for Structural Joints requirements. Power down any adjacent electrical equipment and follow applicable jobsite lockout procedures before working in steel framing bays. A TC wrench is required to shear the splined end, confirming proper pretension has been achieved. Do not reuse tension control bolts once the spline has been sheared.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.875 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: A325\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 A325, ASTM F1852\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, Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\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: TCB31000250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714345206066,"sku":"TCB31000250","price":76.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a390952740b356296a913cb3f1614f6_65969e00-6f07-4949-b579-0d1f84f3eb7e.jpg?v=1788499909","url":"https:\/\/voomisupply.com\/products\/value-collection-tcb31000250-tension-control-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
