It features a 1-1\/8-7 UNC thread size with a 5-1\/2 inch length under head and is partially threaded, allowing the unthreaded shank to carry shear loads. Manufactured from steel to ASTM A325 specifications and finished with a hot-dipped galvanized coating, this bolt delivers both the tensile strength required for structural connections and corrosion resistance for demanding environments. Licensed tradespeople and contractors rely on this grade for high-strength structural steel connections.\u003c\/p\u003e\n\u003cp\u003eThis bolt is used in structural steel construction, heavy equipment assembly, and industrial fabrication where ASTM A325 compliance is specified. The hot-dipped galvanized finish makes it suitable for exterior and high-moisture environments. The partially threaded shank is appropriate for bolted connections where the bolt passes through multiple plies of steel and the threads engage only the nut side, which is standard practice in structural steel framing and beam connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM A325 grade steel construction for high-strength structural fastening\u003c\/li\u003e\n  \u003cli\u003e1-1\/8-7 UNC thread size with 5-1\/2 inch length under head\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank to carry shear loads in bolted connections\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish for corrosion resistance in exterior and wet environments\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; compatible with standard UNC hex nuts and washers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ASTM A325-compliant structural hex head bolt for use with standard 1-1\/8-7 UNC heavy hex nuts and hardened washers in structural steel connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of ASTM A325 structural bolts should be performed by qualified ironworkers or structural tradespeople following AISC and RCSC specifications for structural bolting. Bolts must be tightened to the specified pretension using the turn-of-nut, calibrated wrench, direct tension indicator, or twist-off method as required by the project engineer. Always use hardened washers under the turned element. Inspect threads and galvanized coating for damage before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/8-7\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: 5-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Partially Threaded\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\u003eFinish\u003c\/strong\u003e: Hot-Dipped Galvanized\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: 2.58 pounds\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: HCI31120550NG-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691490705714,"sku":"HCI31120550NG-005BX","price":36.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6148b005c55adefbede627bfaf3895b8_b2df5eb1-46c9-4135-adf9-e76e3730098e.jpg?v=1788285836","url":"https:\/\/voomisupply.com\/products\/value-collection-hci31120550ng-005bx-hex-head-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
