This A490-grade fastener uses a splined end that shears off when the correct installation torque is reached, providing a reliable, built-in clamp force indicator. The assembly includes a matching nut and washer. With a 3\/4-10 UNC thread, a 6-inch length under head, and a 1-3\/8 inch head diameter, this bolt is sized for heavy structural steel joints in commercial and industrial framing applications. Installation is performed by licensed structural ironworkers and steel erectors working to applicable building codes.\u003c\/p\u003e\u003cp\u003eTension control bolts in this configuration are used in structural steel connections for commercial buildings, bridges, and industrial structures. The A490 material grade meets ASTM A490 and ASTM F2280 standards, making this fastener appropriate for high-load applications where precise pretension is required. The bright, uncoated finish is typical for interior or painted structural assemblies where additional corrosion protection will be applied by the contractor.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA490-grade steel meets ASTM A490 and ASTM F2280 standards for high-strength structural bolting\u003c\/li\u003e\n\u003cli\u003eSplined shear-type design provides built-in installation torque control without a torque wrench\u003c\/li\u003e\n\u003cli\u003e3\/4-10 UNC thread size for compatibility with standard structural bolt holes\u003c\/li\u003e\n\u003cli\u003e6-inch length under head accommodates substantial grip ranges in multi-layer steel connections\u003c\/li\u003e\n\u003cli\u003eIncludes matching nut and washer for a complete fastener assembly\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for assemblies receiving field-applied coatings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-strength structural tension control bolt conforming to ASTM A490 and ASTM F2280, suitable for use in standard 3\/4-inch structural bolt applications where A490 pretensioned bolting is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of A490 tension control bolts must be performed by qualified ironworkers in accordance with the AISC Specification for Structural Steel Buildings and applicable project specifications. A tension control wrench is required to engage the splined end and shear it at the specified pretension load. Confirm all mating surfaces are free of debris and mill scale as required by the connection design before assembly. Do not reuse tension control bolts once the spline has been sheared.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1-3\/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: Nut, 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\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: TCI40750600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712098894130,"sku":"TCI40750600","price":76.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d941b3e4eee2bb9576555a480514d91d.jpg?v=1788483805","url":"https:\/\/voomisupply.com\/products\/value-collection-tci40750600-tension-control-bolt-a490","provider":"Voomi Supply","version":"1.0","type":"link"}
