Manufactured to ASTM A325 specifications, this bolt features a 1-1\/8-7 UNC thread size and a 7.5-inch length under head with partial threading. The hot-dipped galvanized finish provides corrosion resistance in outdoor and exposed environments. At 3.126 pounds per unit, this is a substantial structural fastener suited for steel-to-steel connections in construction, industrial, and heavy equipment assemblies. Installation requires standard hex tooling and is typically performed by ironworkers, millwrights, or structural mechanics following applicable torque and tightening specifications defined by project engineering documents.\u003c\/p\u003e\n\u003cp\u003eThis bolt is commonly used in structural steel connections, bridge construction, heavy machinery mounting, and industrial fabrication where ASTM A325 compliance is specified by engineers or inspectors. The partial threading leaves a smooth shank section that resists shear forces in bearing-type connections. The hot-dipped galvanized finish makes it suitable for exterior, high-humidity, or chemically exposed environments where bare steel would corrode. It is typically specified on projects governed by AISC, RCSC, or similar structural steel standards requiring documented bolt grades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM A325 certified high-strength structural bolt\u003c\/li\u003e\n  \u003cli\u003e1-1\/8-7 UNC thread size with partial threading for shear-bearing connections\u003c\/li\u003e\n  \u003cli\u003e7.5-inch length under head accommodates thicker steel stack assemblies\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish for corrosion resistance in exposed environments\u003c\/li\u003e\n  \u003cli\u003eSteel construction meeting Grade A325 material and mechanical property requirements\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 in steel-to-steel structural connections where 1-1\/8-7 UNC fasteners are specified by engineering or project documentation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified tradespeople following AISC and RCSC specifications for structural bolt tightening. Power down or de-energize any adjacent systems before working in the installation area. Use calibrated torque wrenches or tension-control tools appropriate to the bolt diameter and specified pretension values defined in the project engineering documents. Do not substitute torque values without consulting the applicable structural specification.\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: 7.5 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\u003eThreading\u003c\/strong\u003e: Partially Threaded\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: 3.126 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: HCI31120750NG-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693148373298,"sku":"HCI31120750NG-005BX","price":66.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81ddbe7a115027660d1f8cba3c4a99c7.jpg?v=1788307995","url":"https:\/\/voomisupply.com\/products\/value-collection-hci31120750ng-005bx-hex-head-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
