Manufactured to ASTM A490 and ASTM F2280 standards, this bolt features a 1-8 UNC thread form, a 4-inch length under head, and a 1-7\/8-inch head diameter. It is supplied uncoated (bright finish) and arrives as a complete assembly that includes a mating nut and washer. Licensed ironworkers and structural steel erectors install these fasteners using TC wrench tooling rated for A490-grade assemblies. Each package contains 5 complete bolt assemblies.\u003c\/p\u003e\u003cp\u003eTension control bolts in the A490 grade are specified for high-load structural steel connections in commercial construction, industrial facilities, and infrastructure projects. The splined shear-end design allows installation from a single side of the joint, which is particularly useful in beam-to-column, beam-to-beam, and splice plate connections where two-sided access is limited. This part is intended for inch-measurement structural applications using standard UNC threading.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eASTM A490 and ASTM F2280 certified for high-strength structural bolt applications\u003c\/li\u003e\n\u003cli\u003e1-8 UNC thread standard for inch-measurement structural steel work\u003c\/li\u003e\n\u003cli\u003e4-inch length under head accommodates multi-ply structural connections\u003c\/li\u003e\n\u003cli\u003eSplined tension control design allows single-side installation with TC wrench tooling\u003c\/li\u003e\n\u003cli\u003eIncludes matching nut and washer for complete joint assembly\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for painted or primed steel applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style structural fastener for inch-series high-strength bolted connections conforming to ASTM A490 and ASTM F2280 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by qualified ironworkers or structural steel erectors following AISC and RCSC bolt installation specifications. Use a TC wrench matched to A490 splined tension control assemblies; do not substitute an impact wrench rated below the required shank torque class. Inspect faying surfaces and joint plies for compliance before snug-tightening. Do not reuse A490 tension control assemblies once the splined end has sheared during initial installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1-7\/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 (per package)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161613\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: TCI41000400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691603067186,"sku":"TCI41000400","price":112.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a9ab4856b9f307802ce5c472892d5bc.jpg?v=1788287661","url":"https:\/\/voomisupply.com\/products\/value-collection-tci41000400-tension-control-bolt-a490","provider":"Voomi Supply","version":"1.0","type":"link"}
