This bolt meets ASTM A490 and ASTM F2280 standards and features a 7\/8-9 UNC thread with a 4-inch length under head. The 1-5\/8-inch head diameter and included nut and washer make this a complete fastener assembly. It arrives with a bright uncoated finish, making it suitable for use where a galvanized or coated fastener is not required. Licensed structural ironworkers and steel erectors are the primary installers of this fastener type.\u003c\/p\u003e\n\u003cp\u003eThis tension control bolt is used in structural steel connections where high-strength fasteners are required by design specification. Typical applications include beam-to-column connections, moment frames, and shear tab assemblies in commercial and industrial steel construction. The ASTM A490 material grade makes it appropriate for heavy structural loads. Each package contains 5 complete bolt assemblies, each including a nut and washer. The inch measurement system and UNC thread standard make this compatible with standard structural steel fabrication practices.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM A490 and ASTM F2280 compliant high-strength structural bolt\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread with 4-inch length under head\u003c\/li\u003e\n  \u003cli\u003e1-5\/8-inch head diameter for standard structural washer seating\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for unpainted or field-painted structural steel applications\u003c\/li\u003e\n  \u003cli\u003eIncludes nut and washer — complete fastener assembly per bolt\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 5 with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ASTM A490 and ASTM F2280 compliant tension control bolt for structural steel connections requiring 7\/8-9 UNC high-strength fasteners per applicable engineering specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of ASTM A490 tension control bolts must be performed by qualified structural ironworkers or licensed contractors in accordance with AISC and RCSC bolt installation specifications. De-energize and lock out any nearby electrical hazards before working in the connection zone. Tension control bolts are installed using a shear-wrench tool that spalls the spline end when proper pretension is achieved — do not substitute standard impact wrenches without confirming pretension requirements. Inspect installed assemblies for proper nut engagement and washer placement per project specifications before final inspection.\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 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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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\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: TCI40870400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693674889522,"sku":"TCI40870400","price":86.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01241f56952eccc85d1e560cfb4882c2.jpg?v=1788315889","url":"https:\/\/voomisupply.com\/products\/value-collection-tci40870400-tension-control-bolt-7-8-9","provider":"Voomi Supply","version":"1.0","type":"link"}
