Threaded 6-40 UNF with a 1\/2 inch length under head, it accepts a 7\/64 inch hex key drive and is fully threaded along its entire shank. Manufactured from alloy steel and finished with a black oxide coating, the 73022 delivers improved corrosion resistance alongside the high tensile strength expected from an alloy steel cap screw. It conforms to ASME B18.3 and ASTM A574 standards. This fastener is installed by machinists, maintenance technicians, and assembly professionals in precision mechanical and industrial applications.\u003c\/p\u003e\n\u003cp\u003eThe 73022 is suited for use in tight-clearance assemblies where a standard hex head fastener will not fit. The 6-40 UNF fine thread pitch provides stronger thread engagement and better resistance to loosening under vibration compared to coarse thread equivalents. Typical applications include instrument panels, light machinery, electronic enclosures, and other precision assemblies where a low-profile, flush-seating fastener is required. The black oxide finish makes it a common choice in applications where light corrosion protection and a non-reflective appearance are both factors.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-40 UNF fine thread for strong engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank along the entire 1\/2 inch length under head\u003c\/li\u003e\n  \u003cli\u003e7\/64 inch hex socket drive for use in confined spaces\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides light corrosion and oxidation resistance\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-fit hex socket cap screw for assemblies specifying a 6-40 UNF fully threaded socket head fastener per ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 7\/64 inch hex key or Allen driver; use of a calibrated torque driver is recommended in precision assemblies to avoid overloading the fine thread. Ensure mating tapped holes are clean and free of debris before driving. Do not use an impact driver on fine-thread socket cap screws of this size. Follow applicable industry or equipment manufacturer torque guidelines for the fastener grade and thread size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-40 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/2 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: 7\/64 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: 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: 73022\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51739837235506,"sku":"73022","price":4486.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7d7bf7d5591a1f0996f6cd0675bd301.jpg?v=1788819400","url":"https:\/\/voomisupply.com\/products\/holo-krome-73022-hex-socket-cap-screw-6-40-unf-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
