The assembly includes a nut and spline-drive washer, and is used where pre-tensioned high-strength bolting is required per ASTM A490 and ASTM F2280 standards. The splined shank shears off during installation when the specified clamp load is reached, providing a built-in tension indicator. Thread size is 1-8 UNC with a length under head of 3.5 inches and a head diameter of 1.875 inches. This bolt is intended for licensed structural ironworkers and contractors working to applicable building and structural codes.\u003c\/p\u003e\n\u003cp\u003eThis tension control bolt is suited for structural steel erection in commercial, industrial, and heavy civil construction. It is installed in bearing-type or slip-critical connections where ASTM A490 high-strength bolt specifications are called out on structural drawings. Each package contains 5 complete assemblies, each including the bolt, nut, and washer. The bright uncoated finish is standard for field-installed structural fasteners where paint or coating is applied after erection or where bare steel is acceptable per project specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM A490 and ASTM F2280 compliant for high-strength structural bolting applications\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC thread standard ensures compatibility with standard heavy-hex structural nuts\u003c\/li\u003e\n  \u003cli\u003eSpline-drive design shears at target clamp load, eliminating separate torque verification\u003c\/li\u003e\n  \u003cli\u003eEach assembly includes bolt, nut, and washer ready for field installation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for painted or bare structural steel applications\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 5 assemblies with a minimum order quantity of 1 package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit tension control bolt for structural steel connections requiring ASTM A490 high-strength fasteners in 1-8 UNC thread size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of ASTM A490 tension control bolts is performed by qualified structural ironworkers in accordance with AISC and RCSC specifications for structural joints. Power off or de-energize any adjacent electrical systems before working in structural bays near live conductors. Use an electric or pneumatic TC bolt shear wrench rated for 1-inch bolt assemblies. Do not reuse a tension control bolt assembly once the spline has sheared, as clamp load verification is no longer possible.\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: 3.5 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: 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: 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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound (per package)\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: TCI41000350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701799223602,"sku":"TCI41000350","price":108.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9adc1971e5b3fdc151ac1b79e541ff94.jpg?v=1788405162","url":"https:\/\/voomisupply.com\/products\/value-collection-tci41000350-tension-control-bolt-a490","provider":"Voomi Supply","version":"1.0","type":"link"}
