It is manufactured from steel to ASTM A325 specifications, which sets minimum tensile strength and mechanical property requirements for structural bolts. The bolt measures 3 inches in length under the head and features partial threading, leaving a smooth shank section that resists shear loads in bolted connections. The uncoated bright finish indicates no additional surface treatment. This fastener is installed by ironworkers, structural steel erectors, millwrights, and maintenance mechanics working on steel-to-steel connections.\u003c\/p\u003e\u003cp\u003eThis bolt is suited for structural steel connections in both commercial and industrial settings. Typical applications include beam-to-column connections, base plate anchoring, equipment mounting, and general structural assembly where ASTM A325 grade hardware is specified by engineering drawings or code. The partially threaded design is particularly relevant in shear-critical connections where the bolt shank bears load across a joint interface rather than through thread engagement alone. The UNC thread standard ensures compatibility with standard hex nuts and washers in inch-based fastener systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eASTM A325 grade steel meets structural bolt standards for tensile and proof load requirements\u003c\/li\u003e\n\u003cli\u003e5\/8-11 UNC thread size fits standard inch-series hex nuts and threaded components\u003c\/li\u003e\n\u003cli\u003e3-inch length under head accommodates typical structural connection stack-ups\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides a smooth bearing surface for shear load transfer\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish suitable for painted, primed, or galvanized connection assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in structural steel connections where ASTM A325 hex head bolts with 5\/8-11 UNC threading are specified.

Snug-tighten all bolts in a connection before applying final pretension using the turn-of-nut, tension-control, or direct-tension-indicator method as specified by the engineer of record. Do not use impact tools without verifying that the selected tightening method permits it. Inspect for proper thread engagement and confirm washer placement under the turned element before final tightening.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\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: 3 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: Uncoated \/ Bright\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: HCI30620300N-020BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696818716978,"sku":"HCI30620300N-020BX","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff657a25b882a7bb11ae825c98de56e1.jpg?v=1788346630","url":"https:\/\/voomisupply.com\/products\/value-collection-hci30620300n-020bx-hex-head-bolt-5-8-11","provider":"Voomi Supply","version":"1.0","type":"link"}
