It features a 5-40 UNC thread and a 1\/2-inch length under head, driven by a 3\/32-inch hex key. Constructed from 18-8 stainless steel, it offers corrosion resistance suitable for environments where moisture or mild chemicals are present. This fastener is installed by machinists, maintenance technicians, and assembly professionals who require reliable clamping force in tight spaces where a standard hex-head wrench cannot reach.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light-duty mechanical assemblies, instrument housings, electrical enclosures, and precision equipment where a flush or recessed fastener head is required. The 5-40 UNC thread is a fine-pitch unified coarse thread in the number-5 diameter range, commonly found in small mechanical and electronic assemblies across industrial and commercial applications. Sold individually; minimum order quantity is 100 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-40 UNC thread for compatibility with standard number-5 tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch length under head for adequate thread engagement in typical light-duty assemblies\u003c\/li\u003e\n  \u003cli\u003e3\/32-inch hex drive allows installation in confined or recessed locations\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003eLow-profile socket cap head style suits flush-mount and space-constrained applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or new-installation hex socket cap screw for any assembly with a 5-40 UNC tapped hole requiring a 1\/2-inch under-head length fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/32-inch hex key or Allen driver. Ensure the receiving tapped hole is clean and free of debris before driving the screw. Apply appropriate thread-locking compound if vibration is a concern in the application. Do not overtighten, as stainless steel fasteners are susceptible to galling if driven at excessive speed or torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/2 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\/32 inch\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: 0.003 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: R40660404\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716132995378,"sku":"R40660404","price":1457.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5dc5208c6d59f60c62f56bdd1a62a1b.jpg?v=1788522213","url":"https:\/\/voomisupply.com\/products\/value-collection-r40660404-hex-socket-cap-screw-5-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
