Manufactured to ASTM A490 and ASTM F2280 standards, this bolt uses a splined end that shears off at a predetermined torque, confirming proper pretension without the need for a torque wrench or turn-of-nut verification. The 7\/8-9 UNC thread and 5-inch length under head make it suited for moderate-to-heavy structural assemblies. Each unit ships with a mating nut and washer. The assembly is bright and uncoated, appropriate for applications where field painting or galvanizing will follow installation.\u003c\/p\u003e\n\u003cp\u003eTension control bolts are used in structural steel framing for commercial and industrial construction projects. Typical applications include beam-to-column connections, moment frames, and braced-frame assemblies where AISC or RCSC bolt specifications require pretensioned installation. The 7\/8-9 thread size is one of the most common diameters in structural steel work. This bolt is installed by ironworkers and structural steel erectors. The package includes 5 complete assemblies, each consisting of a bolt, nut, and washer.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM A490 and ASTM F2280 certified for high-strength structural applications\u003c\/li\u003e\n  \u003cli\u003eSplined shear end confirms proper pretension at installation without torque wrench measurement\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread with 5-inch length under head for moderate-to-heavy steel connections\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish compatible with post-installation field coating\u003c\/li\u003e\n  \u003cli\u003eEach assembly includes bolt, nut, and washer\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 5 assemblies per unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-strength structural replacement for 7\/8-9 UNC tension control bolt assemblies meeting ASTM A490 and ASTM F2280 fastener standards in structural steel connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified ironworkers or structural steel erectors in accordance with AISC and RCSC Specification for Structural Joints requirements. A tension control bolt gun with the appropriate 7\/8-inch socket and inner spline socket is required to drive the bolt and shear the splined end. Do not reuse tension control bolt assemblies once the splined end has sheared. Verify that faying surfaces and hole alignment comply with project structural drawings before fastening.\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: 5 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\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: Bolt, Nut, 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\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: TCI40870500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699911688498,"sku":"TCI40870500","price":95.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5550b8fb95aaebd204666db5ba5e8c80.jpg?v=1788383162","url":"https:\/\/voomisupply.com\/products\/value-collection-tci40870500-tension-control-bolt-7-8-9","provider":"Voomi Supply","version":"1.0","type":"link"}
