It features an 82-degree flat head geometry and a 1\/16-inch hex socket drive. The screw is fully threaded in a 4-40 UNC thread configuration and measures 1\/2 inch in overall length. Constructed from alloy steel with a black oxide finish, it provides solid mechanical strength and moderate corrosion resistance in controlled environments. This fastener is commonly installed by machinists, maintenance technicians, and assembly professionals working with light-duty threaded hardware.\u003c\/p\u003e\u003cp\u003eThis flat socket cap screw is suited for applications where the fastener head must sit flush with or below the surface of the mating material. Typical use cases include instrument assemblies, electronic enclosures, jig and fixture construction, and precision mechanical assemblies. The 4-40 thread size and 1\/2-inch length make it a common choice for small-frame components and light structural connections in both production and field-repair settings. Orders must be placed in multiples of 100 units, and each package contains 1 piece.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree flat head for flush or countersunk installation\u003c\/li\u003e\n\u003cli\u003e1\/16-inch hex socket drive for precise torque application\u003c\/li\u003e\n\u003cli\u003eFully threaded 4-40 UNC configuration along the entire 1\/2-inch length\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for dependable mechanical strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-dimension replacement or production fastener for any application requiring a 4-40 UNC fully threaded flat socket cap screw with an 82-degree head angle, conforming to ASME\/ANSI B18.3 and ASTM F835 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or technician using a 1\/16-inch hex key or compatible socket driver. Ensure the receiving material is properly tapped to 4-40 UNC specifications before driving the fastener. Do not exceed the rated drive torque for the 4-40 thread class, and inspect the countersink angle of the mating part to confirm it matches the 82-degree head geometry before final assembly.\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\u003eLength\u003c\/strong\u003e: 1\/2 inches (overall)\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 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F835\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.00129 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 piece\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: 211019PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722085073202,"sku":"211019PR","price":1361.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2715879b32161aa20bfc0ea0b4c3044b.jpg?v=1788585409","url":"https:\/\/voomisupply.com\/products\/value-collection-211019pr-flat-socket-cap-screw-4-40-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
