It features a 1-1\/4-7 UNC thread size and a 3-1\/4 inch length under head, manufactured from uncoated steel to ASTM A325 structural bolt standards. The A325 grade indicates high-strength performance suitable for steel-to-steel connections in load-bearing assemblies. The bright, uncoated finish means no additional coating process has been applied, making it appropriate for installations where coating is specified separately or not required. Licensed tradespeople and construction professionals working with structural steel connections will find this bolt meets the dimensional and mechanical requirements of ASTM A325.\u003c\/p\u003e\u003cp\u003eThis bolt is suited for structural steel construction, heavy equipment assemblies, and industrial fastening applications where high-strength UNC fasteners are specified. The fully threaded configuration allows maximum thread engagement along the full length of the shank, which is preferred in applications requiring deep thread contact or adjustable clamping depth. It is commonly installed by ironworkers, millwrights, and mechanical contractors working on structural frames, base plates, and heavy machinery mounts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4-7 UNC thread size for high-strength structural fastening\u003c\/li\u003e\n\u003cli\u003e3-1\/4 inch length under head for deep clamping applications\u003c\/li\u003e\n\u003cli\u003eFully threaded shank provides maximum thread engagement\u003c\/li\u003e\n\u003cli\u003eASTM A325 certified high-strength structural bolt standard\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no surface coating applied\u003c\/li\u003e\n\u003cli\u003eInch measurement system, standard hex head drive\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASTM A325 fully threaded hex head bolt for structural steel and heavy-duty industrial fastening applications requiring 1-1\/4-7 UNC thread specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified tradespeople following applicable structural codes, including AISC and RCSC specifications for high-strength bolted connections. Always confirm mating nut thread class and hole clearance before installation. Torque or tension requirements for A325 bolts must be determined from applicable project engineering specifications — do not assume a default value. De-energize and lock out any adjacent energized equipment before working in proximity to electrical systems.\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: 3-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Fully 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: 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\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: HCI31250325N-005BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714011660594,"sku":"HCI31250325N-005BX","price":34.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d3f0904b24269a44554ece56b0f5a43_e3cd446a-7d94-482d-bc06-46d9e1b4f0f3.jpg?v=1788495897","url":"https:\/\/voomisupply.com\/products\/value-collection-hci31250325n-005bx-hex-head-bolt-a325","provider":"Voomi Supply","version":"1.0","type":"link"}
