Threaded to the 1\/4-28 UNF standard, this screw features a 1-1\/4 inch length under head and accepts a 3\/16 inch hex drive key. Constructed from 18-8 stainless steel, it provides reliable resistance to rust and oxidation in both indoor and outdoor environments. Licensed trades and maintenance professionals use this fastener where a flush, recessed-drive connection is required and where standard coarse-thread fasteners are not suitable.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in mechanical assemblies, equipment enclosures, fluid system components, and structural fixtures where the 1\/4-28 UNF fine thread pitch is specified. The fine thread profile delivers higher clamping force per turn compared to coarse-thread equivalents and is commonly called out in aerospace-adjacent, HVAC, plumbing, and electrical panel applications. It is typically installed by maintenance technicians, millwrights, or journeyman-level tradespeople working to engineered fastener specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF fine thread for precise clamping and reduced axial play\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch length under head suits moderate-depth fastening requirements\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion and oxidation\u003c\/li\u003e\n  \u003cli\u003eLow-profile socket cap head allows installation in recessed or counter-bored holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-28 UNF hex socket cap screw for use in any threaded bore or nut conforming to the 1\/4-28 UNF thread standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated 3\/16 inch hex key or socket hex bit driver. Ensure the mating threaded hole or nut is clean and free of debris before driving. Do not over-torque stainless steel fasteners, as galling can occur without proper anti-seize compound applied to the threads. Verify thread engagement depth meets the engineered specification for the assembly before applying final torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/4 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: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.021 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R40694128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721956720946,"sku":"R40694128","price":3008.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7108c0475535a66872c76476f25df47.jpg?v=1788583806","url":"https:\/\/voomisupply.com\/products\/value-collection-r40694128-hex-socket-cap-screw-1-4-28-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
