Threaded 2-56 UNC and fully threaded along its 1\/4 inch length under the head, this fastener accepts a 5\/64 inch hex drive. It is manufactured from 18-8 stainless steel with a bright, uncoated finish, providing corrosion resistance in environments where plated carbon steel is not suitable. The fine thread form holds well under vibration and delivers consistent clamping force in close-tolerance holes. This screw is commonly installed by machinists, maintenance technicians, and mechanical assemblers working on precision equipment.\u003c\/p\u003e\n\u003cp\u003eThis screw is well suited for small-frame assemblies, instrument panels, enclosures, and light mechanical fixtures requiring a compact, low-profile fastening solution. The 2-56 UNC thread size is a standard choice in precision electrical and mechanical equipment where small fasteners are required. The stainless steel construction makes it appropriate for applications exposed to moisture or mild corrosive conditions where a standard steel fastener would degrade over time.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-56 UNC thread form for precision small-diameter fastening\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the entire 1\/4 inch under-head length\u003c\/li\u003e\n  \u003cli\u003e5\/64 inch internal hex drive accepts standard hex keys\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating thickness to account for in close-tolerance holes\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.3 and ASTM F837 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or stock fastener for assemblies requiring a 2-56 UNC hex socket cap screw with a 1\/4 inch under-head length, conforming to ASME B18.3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated 5\/64 inch hex key or hex bit driver; avoid oversized or worn drivers that can strip the socket. Ensure the mating tapped hole is clean and free of debris before installation. Do not apply excessive torque — small-diameter stainless fasteners are susceptible to galling and thread seizure; use an appropriate anti-galling lubricant where torque consistency is critical. Follow applicable mechanical assembly standards for the specific equipment or enclosure being serviced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 2-56 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\u003eThreading\u003c\/strong\u003e: Fully 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: 5\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel, 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: 78004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51729623875890,"sku":"78004","price":7555.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc9e89e6793841dd8c0b834bd3919a31.jpg?v=1788706886","url":"https:\/\/voomisupply.com\/products\/holo-krome-78004-hex-socket-cap-screw-2-56-unc-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
