It features a 1\/2-13 UNC thread and measures 1.5 inches in length under the head. The drive is a 3\/8 inch internal hex socket, requiring an Allen key or hex bit driver for installation. Constructed from 18-8 stainless steel with a bright, uncoated finish, this screw offers solid corrosion resistance for both indoor and outdoor environments. It is fully threaded along its entire shank length and conforms to ASME B18.3 and ASTM F837 standards. Installers in mechanical, plumbing, HVAC, and general fabrication trades will find this fastener suitable for a wide range of structural and equipment assembly tasks.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for use in residential and commercial applications where a recessed hex drive head is preferred over a standard hex head or Phillips drive. Typical installation scenarios include equipment panel mounting, pump and motor assembly, pipe flange fastening, and structural bracket attachment. The 1\/2-13 UNC coarse thread provides strong clamping force and is well-suited for use in standard tapped steel, aluminum, or stainless steel receiving materials. The uncoated stainless finish makes it suitable for use in moist or corrosive environments without requiring additional protective treatment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC coarse thread for reliable engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1.5 inch length under head suits medium-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch internal hex socket drive for use with Allen keys or hex bit tools\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank maximizes thread engagement across the full grip length\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance without coating\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.3 and ASTM F837 standards for dimensional and mechanical conformance\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 equipment and assemblies requiring a 1\/2-13 UNC hex socket cap screw with a 1.5 inch length under head in 18-8 stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/8 inch hex key or hex bit driver rated for the applied torque. Ensure the receiving hole is properly tapped to 1\/2-13 UNC before installation. Power down or depressurize any equipment before replacing fasteners on live systems. Avoid mixing stainless steel fasteners with dissimilar metals in submerged or highly conductive environments to minimize galvanic corrosion risk.\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: 1.5 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: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3, ASTM F837\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: 78116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51788010815794,"sku":"78116","price":3935.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c9a2a0009891924a2ca223b5da382b3_839f7114-b9d7-42da-a507-68eabfea1b86.jpg?v=1789221655","url":"https:\/\/voomisupply.com\/products\/holo-krome-78116-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
