Machined from 18-8 stainless steel, this fastener features a 1\/4-20 UNC thread and a 3.5-inch length under head. Drive engagement is provided by a 3\/16-inch hex socket, compatible with standard Allen keys and hex bit drivers. The 18-8 stainless steel construction provides solid resistance to oxidation and mild chemical exposure, making it well suited for installations in humid or outdoor-adjacent environments.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in light to medium-duty mechanical assemblies across HVAC equipment, plumbing fixtures, electrical enclosures, and general industrial applications. The 1\/4-20 UNC thread is one of the most common coarse-thread sizes in trade work, and the 3.5-inch length under head accommodates fastening through moderate material stack-ups. Technicians and assemblers working with sheet metal panels, equipment housings, or structural brackets will find this a standard-duty replacement or new-installation fastener.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in humid and mildly corrosive environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC coarse thread for broad compatibility with standard tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for use with Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003e3.5-inch length under head accommodates deeper fastening through stacked materials\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 31161501 for procurement and catalog classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC hex socket cap screw suitable for use wherever a 1\/4-20 coarse-thread fastener with a 3\/16-inch hex drive is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/16-inch hex key or appropriately sized hex bit driver. Ensure the receiving thread is clean and free of debris before driving. When fastening into dissimilar metals, consider using anti-seize compound to prevent galling of the stainless threads. Verify thread engagement depth meets the requirements of the application before torquing to final specification.\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: 3.5 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: 0.05 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: R40684204\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690775642418,"sku":"R40684204","price":934.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c4f89f102dc1bb3b41c60fa80c857cb.jpg?v=1788275392","url":"https:\/\/voomisupply.com\/products\/value-collection-r40684204-hex-socket-cap-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
