This 7\/8-9 UNC threaded fastener measures 4-3\/4 inches under the head and is manufactured from Grade A490 steel, meeting ASTM A490 and ASTM F2280 standards. Each bolt arrives as a complete assembly including a compatible nut and washer, ready for direct installation. The uncoated bright finish is standard for structural steel applications where field painting or coating will be applied after erection. Licensed ironworkers and structural steel contractors are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis tension control bolt is suited for structural steel framing in commercial and industrial construction, including beam-to-column connections, moment frames, and bolted splice plates. The 7\/8-9 thread size is among the most common specifications called out in structural steel connection designs. Package quantity is 5 assemblies per unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade A490 high-strength steel meets ASTM A490 and ASTM F2280 fastener standards\u003c\/li\u003e\n  \u003cli\u003eComplete assembly includes nut and washer for single-source procurement\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread with 4-3\/4 inches length under head suits heavy structural connections\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish compatible with field-applied coatings and galvanizing\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 5 assemblies supports small-run and repair work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style structural replacement fastener for 7\/8-9 UNC tension control bolt applications conforming to ASTM A490 and ASTM F2280 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTension control bolts are installed by licensed ironworkers or structural steel contractors using a shear-wrench tool that engages the splined end of the bolt and shears it off at the specified tension — no torque wrench calibration is required by design. Follow AISC and RCSC bolt installation specifications, including inspection requirements for pre-installation verification and rotational capacity testing. Never reuse tension control bolts once the splined end has been sheared. Ensure mating surfaces are free of mill scale, paint, and debris as required by the connection design documents.\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: 4-3\/4 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 assemblies\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound (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: TCI40870475\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696469475634,"sku":"TCI40870475","price":93.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86012d1133640e4c247f63f788638b31.jpg?v=1788343017","url":"https:\/\/voomisupply.com\/products\/value-collection-tci40870475-tension-control-bolt-a490","provider":"Voomi Supply","version":"1.0","type":"link"}
