This bolt meets ASTM A490 and ASTM F2280 standards, making it suitable for heavy structural assemblies where precise clamping force is critical. The tension control design uses a splined end that shears off at a calibrated torque, eliminating the need for a torque wrench and reducing installer error. Thread size is 1-8 UNC, length under head is 5.5 inches, and head diameter is 1.875 inches. Each set includes a compatible nut and washer. Installed by ironworkers and structural steel erectors on commercial and industrial projects.\u003c\/p\u003e\u003cp\u003eThis tension control bolt is used in structural steel connections on commercial buildings, bridges, industrial frames, and similar heavy construction applications. The A490 material grade indicates a high-strength alloy steel fastener appropriate for demanding load-bearing joints. The bright uncoated finish is standard for structural bolt sets used in dry or painted steel assemblies. This package contains 5 complete bolt sets, each including the bolt, nut, and washer.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eASTM A490 and ASTM F2280 compliant for structural high-strength applications\u003c\/li\u003e\n\u003cli\u003eTension control splined end shears at calibrated torque for consistent preload\u003c\/li\u003e\n\u003cli\u003e1-8 UNC thread standard ensures compatibility with standard structural hardware\u003c\/li\u003e\n\u003cli\u003eEach set includes nut and washer for a complete installation unit\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for painted or dry structural steel assemblies\u003c\/li\u003e\n\u003cli\u003ePackaged in quantities of 5 bolt sets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in structural steel connections conforming to ASTM A490 and ASTM F2280 specifications.

Before installation, inspect hole alignment and ensure mating steel surfaces are clean and free of debris. A TC wrench or shear wrench is required to engage the splined end and achieve proper preload. Do not reuse tension control bolts that have had their splined end sheared.\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: 5.5 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: Nut and 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: TCI41000550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720870691122,"sku":"TCI41000550","price":131.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c20abc2c09dfeb1e0ac81b4ad0e7da4_9f45dca4-b039-4329-9499-2e4a091b9504.jpg?v=1788570268","url":"https:\/\/voomisupply.com\/products\/value-collection-tci41000550-tension-control-bolt-a490","provider":"Voomi Supply","version":"1.0","type":"link"}
