Manufactured from 18-8 stainless steel with a bright, uncoated finish, this screw provides corrosion resistance suitable for general industrial, mechanical, and light-duty structural assemblies. The hex socket drive accepts a 1\/16-inch hex key for installation in confined spaces where a standard driver cannot reach. Thread length under the head measures 3\/8 inches, and the thread fit class is 3A per ANSI\/ASME B18.3 and ASTM F837 standards. Sold in a package of 50 pieces.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for residential and commercial applications requiring a compact, corrosion-resistant screw in light-gauge assemblies, electronics enclosures, instrumentation panels, and precision mechanical components. The 4-40 UNC thread size is common in small-device fabrication, HVAC control board mounting, and equipment chassis assembly where clearance around the fastener head is limited. Licensed tradespeople and fabricators working to ANSI specifications will find this screw a direct fit for standard 4-40 tapped holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18-8 stainless steel construction for corrosion resistance in damp or mildly corrosive environments\u003c\/li\u003e\n\u003cli\u003eButton head profile reduces protrusion and provides a smooth, low-profile seating surface\u003c\/li\u003e\n\u003cli\u003e1\/16-inch hex socket drive allows installation in tight, recessed, or confined locations\u003c\/li\u003e\n\u003cli\u003e3A thread fit class meets ANSI\/ASME B18.3 and ASTM F837 fastener standards\u003c\/li\u003e\n\u003cli\u003eRight-hand UNC thread for compatibility with standard 4-40 tapped holes\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish maintains dimensional tolerances without coating buildup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or stock fastener for any assembly requiring a 4-40 UNC button socket cap screw with a 3\/8-inch length under head.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician or fabricator using a 1\/16-inch hex key or ball-end driver. De-energize and lock out any electrical equipment before installing fasteners in or near live assemblies. Do not overtighten into tapped holes in soft materials such as aluminum or plastic, as the 4-40 thread is fine and susceptible to stripping. Follow applicable ANSI torque guidelines for the base material and thread size.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eThread Fit Class\u003c\/strong\u003e: 3A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\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 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.0590 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 18-8 Stainless Steel\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: ANSI\/ASME B18.3, ASTM F837\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 93052\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697662394674,"sku":"93052","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c27e094f410dbe9a831168c211e3b69.jpg?v=1788353903","url":"https:\/\/voomisupply.com\/products\/value-collection-93052-button-socket-cap-screw-4-40-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
