It features a 1-1\/4-7 UNC thread size with a 5-inch length measured under the head, and is manufactured from uncoated steel meeting ASTM A325 material grade requirements. The partial threading configuration leaves a shank section below the head, which is standard practice in structural connections where shear load transfer through the unthreaded body is required. This bolt is installed by ironworkers, structural steel erectors, and millwrights working on bolted connections in steel construction and heavy equipment.\u003c\/p\u003e\u003cp\u003eThis bolt is suited for structural steel connections in commercial and industrial construction, heavy equipment assembly, bridge work, and similar load-bearing applications where ASTM A325 high-strength fasteners are specified by an engineer or governing code. The 1-1\/4-inch diameter and 5-inch length make it appropriate for thick flange connections and heavy steel-to-steel joints. Partial threading is commonly required in bearing-type and slip-critical connections per AISC and RCSC specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eASTM A325 grade steel meeting high-strength structural fastener requirements\u003c\/li\u003e\n\u003cli\u003e1-1\/4-7 UNC thread for use with standard heavy hex nuts and washers\u003c\/li\u003e\n\u003cli\u003e5-inch length under head for thick structural member connections\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for shear-load-bearing bolted joints\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for painted or galvanized connection assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an ASTM A325 high-strength hex head bolt for use in structural steel bolted connections requiring 1-1\/4-7 UNC thread size and 5-inch grip length applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of ASTM A325 structural bolts should be performed by qualified ironworkers or structural steel erectors following AISC and RCSC specification requirements. Always use the specified nut grade and hardened washers as required by the connection design. Snug-tighten the bolt before applying final pretension using the turn-of-nut, tension-control, or direct tension indicator method as specified. Do not reuse A325 bolts that have been fully tensioned unless permitted by the applicable specification.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4-7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: 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\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\u003eStandard\u003c\/strong\u003e: ASTM A325\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Style\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HCI31250500N-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695366242610,"sku":"HCI31250500N-005BX","price":30.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d3f0904b24269a44554ece56b0f5a43.jpg?v=1788334282","url":"https:\/\/voomisupply.com\/products\/value-collection-hci31250500n-005bx-hex-head-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
