It features a 1-1\/2-6 UNC thread profile and a 4-inch length under the head, with full threading along the entire shank. The screw is manufactured from alloy steel and finished with a black oxide coating to provide moderate corrosion resistance and a uniform dark appearance. Drive is a 1-inch internal hex socket. Torque is applied with a standard hex key or Allen driver. Installers in manufacturing, heavy equipment maintenance, and industrial construction commonly use this fastener where high tensile strength is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for structural and mechanical fastening in heavy industrial, OEM machinery, and maintenance-repair-operations (MRO) environments. Fully threaded construction makes it appropriate for through-hole and tapped-hole applications where thread engagement along the full fastener length is required. The coarse 6 TPI pitch aids in fast assembly and provides reliable clamp load in steel and iron assemblies. Trades and technicians working in fabrication, rigging, and industrial equipment service are the primary installers of this fastener.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-6 UNC coarse thread for reliable engagement in steel and iron tapped holes\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank for maximum thread engagement in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n  \u003cli\u003e1-inch internal hex drive for high-torque application with standard hex key tooling\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 a standard hex socket cap screw per ASME B18.3 and ASTM A574, suitable for use in any tapped or through-hole application requiring a 1-1\/2-6 UNC thread and 4-inch under-head length in alloy steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1-inch hex key or socket driver rated for the applicable torque load. Always verify that the mating tapped hole or nut meets the same thread specification (1-1\/2-6 UNC) before assembly. Follow applicable industry or OEM torque specifications for ASTM A574 alloy steel cap screws of this diameter. Ensure mating surfaces are clean and free of debris before tightening to achieve proper clamp load.\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\/2-6 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\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: 1 inch\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\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.42 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: 72430\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51743024546098,"sku":"72430","price":105.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25aa05b210c35d29c16281eabbae7048.jpg?v=1788841708","url":"https:\/\/voomisupply.com\/products\/holo-krome-72430-hex-socket-cap-screw-1-1-2-6-unc-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
