Manufactured from alloy steel and finished with a black oxide coating, this screw resists corrosion and reduces light reflection in service environments. It uses a 3\/16 inch hex drive and features a 1\/4-20 UNC thread with a 1\/4 inch length under the head. The fastener is fully threaded along its entire shank length, making it suitable for shallow-clearance assemblies. It meets ASME B18.3 and ASTM A574 standards, which specify dimensional and mechanical requirements for alloy steel socket cap screws commonly used in industrial and mechanical installations.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for general mechanical assembly, tool and die work, machine guarding, and equipment fabrication where an internal-drive fastener is preferred over a hex head bolt. The 1\/4-20 UNC thread is one of the most common unified coarse-thread sizes, making this screw applicable across a wide range of industrial, HVAC component assembly, and electrical enclosure fastening scenarios. The black oxide finish is appropriate for both indoor and light-duty outdoor applications where surface appearance and moderate corrosion resistance are a consideration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical strength requirements for socket cap screws\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides moderate corrosion resistance and a uniform matte appearance\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank allows engagement along the entire fastener length\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex drive accepts standard hex keys and hex-bit drivers\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standards for interchangeability and consistency\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC threading is widely compatible with standard tapped holes in machined metal assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME B18.3 hex socket cap screw for use in any 1\/4-20 UNC tapped hole requiring an alloy steel internal-drive fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or technician using a properly sized 3\/16 inch hex key or socket bit driver. Ensure the mating tapped hole is clean and free of debris before installation. Do not exceed the rated torque for 1\/4-20 alloy steel socket cap screws as specified by applicable engineering or equipment documentation. Avoid using impact drivers that may damage the hex socket recess or over-stress the fastener.\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: 1\/4 inch\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 inch\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: 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: 86526\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51743273845042,"sku":"86526","price":3841.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/667ce3da2b7ff04f2b8da8b08a57723a.jpg?v=1788844881","url":"https:\/\/voomisupply.com\/products\/holo-krome-86526-hex-socket-cap-screw-1-4-20-unc-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
