Featuring an 82-degree flat head and a 1\/16-inch hex socket drive, this screw accepts a standard hex key for installation. Built from 18-8 stainless steel, it provides solid corrosion resistance in general-purpose and light industrial environments. The 4-40 UNC thread and 1\/2-inch overall length make it well suited for close-tolerance assemblies where head clearance is critical. Machinists, fabricators, and maintenance technicians working with light-gauge components will find this screw a practical choice for countersunk fastening tasks.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is used in precision mechanical assemblies, panel fabrication, instrument enclosures, and light machine components where a low-profile flush head is required. The 4-40 UNC thread size is common in small-diameter applications such as electronics enclosures, jigs, fixtures, and light structural brackets. The 18-8 stainless steel construction suits indoor and mildly corrosive environments without sacrificing machinability or installation ease.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head seats flush in standard countersunk holes for a clean, low-profile finish\u003c\/li\u003e\n  \u003cli\u003e1\/16-inch hex socket drive accepts a standard hex key for positive torque transfer in tight spaces\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides good corrosion resistance and moderate strength\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC thread standard ensures compatibility with widely available tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch overall length measured from top of head to tip of thread\u003c\/li\u003e\n  \u003cli\u003eLightweight at approximately 0.003 pounds per piece, suited for weight-sensitive assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 UNC flat socket cap screw for use in countersunk hole patterns requiring an 82-degree head angle; compatible with any application calling for a 4-40 UNC thread, 1\/2-inch overall length, and 82-degree flat hex socket fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/16-inch hex key or Allen driver; ensure the mating hole is properly countersunk to 82 degrees for full head seating. Avoid overtightening in tapped plastic or soft metal components, as 18-8 stainless steel can gall when threaded into stainless tapped holes without lubrication. Power down or de-energize any equipment before accessing fastened assemblies. Follow applicable mechanical and electrical codes for the installation environment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: 82-Degree Flat\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: 1\/16 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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.003 pounds\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: R63008849\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714941124914,"sku":"R63008849","price":442.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/def45b812ae7a22a337288872dcd8038.jpg?v=1788508156","url":"https:\/\/voomisupply.com\/products\/value-collection-r63008849-flat-socket-cap-screw-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
