The fastener uses a splined end that shears off at a calibrated torque, confirming that the required clamping force has been achieved without a torque wrench. It is supplied as a complete assembly that includes the bolt, a compatible nut, and a hardened washer. The bolt is manufactured from A325 steel with a bright uncoated finish and conforms to ASTM A325 and ASTM F1852 standards. Licensed ironworkers and structural steel erectors are the primary installers of this fastener.\u003c\/p\u003e\n\u003cp\u003eThis tension control bolt is intended for use in structural steel framing applications including building frames, bridges, and heavy equipment platforms where pre-tensioned high-strength bolted joints are required by design specification. The 1-8 UNC thread and 5-inch length under head make it suited for medium to heavy plate and flange connections. It is packaged in a quantity of five units per package, which is standard for jobsite use where small quantities are needed for completion work or repair.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSplined shear end provides a positive visual confirmation of proper pre-tension without a torque wrench\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM A325 and ASTM F1852 standards for structural bolting applications\u003c\/li\u003e\n  \u003cli\u003eA325 steel construction delivers the high clamping force required in structural connections\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for use in dry or protected interior steel environments\u003c\/li\u003e\n  \u003cli\u003eComplete assembly includes bolt, nut, and hardened washer for single-source procurement\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of five per package with a minimum order of one package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ASTM A325 and ASTM F1852 compliant tension control bolt for structural steel connections requiring 1-8 UNC thread and a 5-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by qualified ironworkers or structural steel erectors following AISC and RCSC specification requirements for pre-tensioned bolted joints. Use a TC wrench (tension control installation tool) to drive the bolt until the splined end shears, which confirms minimum pre-tension has been achieved. Inspect each sheared spline after installation as required by the project inspection plan. Do not reuse tension control bolts that have had their spline sheared or that have been field modified.\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: 5 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: A325\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 A325; ASTM F1852\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\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: TCB31000500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689586819378,"sku":"TCB31000500","price":92.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a390952740b356296a913cb3f1614f6.jpg?v=1788261462","url":"https:\/\/voomisupply.com\/products\/value-collection-tcb31000500-tension-control-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
