It features a 1-1\/4-7 UNC thread and measures 12 inches in length under the head. The 7\/8 inch hex socket drive accepts a standard hex key or socket driver. Manufactured from alloy steel with a black oxide finish, this fastener delivers corrosion resistance and meets ASME B18.3 and ASTM A574 standards. It is well-suited for structural and heavy-duty fastening applications where precise torque and thread engagement are required.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in heavy industrial machinery, structural steel assemblies, manufacturing equipment, and maintenance applications requiring a large-diameter, high-strength fastener. The coarse 7 UNC thread pitch provides reliable engagement in steel or alloy tapped holes. Partial threading along the shank allows for accurate alignment and load distribution in through-bolt and blind-hole configurations. Machinists, millwrights, and maintenance technicians commonly install this fastener in fabrication shops, processing plants, and equipment repair settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-7 UNC coarse thread for robust thread engagement in heavy steel assemblies\u003c\/li\u003e\n  \u003cli\u003e12 inch length under head accommodates deep through-bolt and structural applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves alignment and distributes shear loads along the bolt body\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch hex socket drive compatible with standard hex keys and socket drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with black oxide coating for corrosion resistance and reduced galling\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit fastener for heavy industrial machinery and structural assemblies requiring a 1-1\/4-7 UNC hex socket cap screw per ASME B18.3 specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, machinists, or maintenance technicians using a calibrated torque wrench and a 7\/8 inch hex socket or hex key. De-energize and lock out all relevant equipment before beginning fastener installation or removal per applicable OSHA lockout\/tagout procedures. Inspect the tapped hole for debris, damage, or misalignment before driving the fastener. Do not substitute thread lubricants or anti-seize compounds without verifying compatibility with the joint design and torque specification established by the equipment manufacturer.\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\/4-7 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.84 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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 720004260\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51753264939314,"sku":"720004260","price":165.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_30c634d1-cfdf-48d0-a797-566fa76a6ee3.jpg?v=1788934669","url":"https:\/\/voomisupply.com\/products\/holo-krome-720004260-hex-socket-cap-screw-1-1-4-7-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
