It features a 1\/4-20 UNC thread size and a body length of 3.25 inches under the head, driven by a 3\/16-inch hex socket. Constructed from alloy steel and finished with a black oxide coating, this fastener meets ASME B18.3 and ASTM A574 standards, making it suitable for demanding mechanical assemblies where strength and corrosion resistance are required. Licensed trades and industrial maintenance technicians rely on this type of fastener for precision installations where a low-profile cap head and internal-drive geometry are necessary.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for use in mechanical, HVAC equipment panels, electrical enclosures, pump housings, and other assemblies that require a high-tensile, internal-drive fastener. Its partially threaded shank provides accurate alignment and strong clamping in through-hole and tapped-hole applications. The black oxide finish offers mild corrosion resistance suitable for indoor and protected environments. This item is sold individually but requires a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread form for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3.25-inch length under head provides ample grip for thick material stacks\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves alignment and shear strength\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish reduces surface friction and provides mild corrosion protection\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-stock hex socket cap screw for any application requiring a 1\/4-20 UNC partially threaded fastener with a 3\/16-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/16-inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before threading to avoid galling or cross-threading. Power down or de-energize any equipment before accessing fastened assemblies. Apply fastener torque per the applicable equipment service manual or relevant ASME fastener torque guidelines for the specific joint material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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: 3\/16 inches\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\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: 86576\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51740369420594,"sku":"86576","price":1351.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91c384ae02a7630303ba22ef078cc974.jpg?v=1788824568","url":"https:\/\/voomisupply.com\/products\/holo-krome-86576-hex-socket-cap-screw-1-4-20-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
