It features a 1\/2-13 UNC thread and measures 3.5 inches under the head with partial threading. The 3\/8-inch hex drive is engaged with a standard hex key or Allen driver. Constructed from alloy steel with a black oxide finish, this screw delivers corrosion resistance and a consistent appearance in demanding environments. It meets ASME B18.3 and ASTM A574 standards, making it appropriate for structural and mechanical assemblies where load-bearing integrity is critical. Licensed professionals and industrial maintenance technicians rely on this fastener type for precision equipment and machinery applications.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in mechanical assemblies, structural fixtures, and industrial equipment installations where a flush or countersunk hex drive is preferred over an external head. The partial threading provides a strong clamping force and is appropriate for through-hole or threaded-insert applications in metal fabrication, equipment mounting, and general industrial maintenance. Its alloy steel construction makes it a reliable choice for applications subject to vibration, torque, and elevated stress loads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread size for compatibility with standard inch-series hardware\u003c\/li\u003e\n  \u003cli\u003e3.5-inch length under head with partial threading for strong clamping force\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex drive accepts standard hex keys and Allen drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 for high-strength fastener requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduced light reflection\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 replacement or standard-service hex socket cap screw for industrial, mechanical, and structural assemblies requiring a 1\/2-13 UNC partially threaded fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, maintenance technicians, or mechanical contractors using a calibrated torque wrench and a 3\/8-inch hex key bit. De-energize and lock out all equipment before servicing fastener connections on powered machinery. Inspect threads and seating surfaces for debris or damage before installation. Do not substitute a fastener of lower grade in applications originally specified for ASTM A574 high-strength cap screws.\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: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partial\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 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\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: 72246\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51740833055026,"sku":"72246","price":9527.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/42bddb3288bca42fb42c9f5b01bc1265.jpg?v=1788827712","url":"https:\/\/voomisupply.com\/products\/holo-krome-72246-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
