Manufactured from alloy steel with a black oxide finish, this fastener meets ASME B18.3 and ASTM A574 standards. It features a 1\/2-13 UNC thread — fully threaded under the head — and measures 1-1\/2 inches in length under head. The low-profile head stands 0.2540 inches tall and accepts a 1\/4-inch hex key drive. This type of fastener is installed by machinists, millwrights, and mechanical contractors working on assemblies with tight vertical clearances.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for industrial machinery, equipment panels, structural assemblies, and fabrication work where a standard socket head cap screw would interfere with mating surfaces or adjacent components. The fully threaded shank provides consistent clamping throughout the grip length, making it appropriate for shallow tapped holes and thin workpiece applications. The black oxide finish offers mild corrosion resistance and reduces surface glare in precision assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLow socket cap head profile — 0.2540 inches head height for tight-clearance installations\u003c\/li\u003e\n  \u003cli\u003eFully threaded 1\/2-13 UNC coarse thread shank\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex socket drive for standard hex key or bit driver\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meeting ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced surface reflectivity\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and aftermarket replacement fastener for industrial and mechanical assemblies requiring a 1\/2-13 UNC low socket cap screw per ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists, millwrights, or mechanical contractors. Ensure the mating tapped hole is clean, undamaged, and cut to 1\/2-13 UNC specification before installation. De-energize and lock out all equipment before fastener replacement per applicable OSHA lockout\/tagout procedures. Use a properly sized 1\/4-inch hex key or bit to avoid rounding the drive socket.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.2540 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Low Socket Cap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Spacing\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 68056\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51733202108722,"sku":"68056","price":13268.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4e7c0d1142c6493142756a10b37f55a.jpg?v=1788752721","url":"https:\/\/voomisupply.com\/products\/holo-krome-68056-low-socket-cap-screw-1-2-13-x-1-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
