The 82-degree flat head sits flush with or below the mating surface when properly countersunk, making it well suited for assemblies where a low-profile or recalibrated surface is required. Drive engagement is through a 5\/16-inch hex socket. The screw is fully threaded along its 1-1\/4-inch overall length and uses a UNF (Unified National Fine) thread standard. It is installed by machinists, millwrights, and maintenance technicians working on mechanical assemblies, fixtures, and tooling.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is used in applications where a flush or countersunk fastener is needed and a fine-thread engagement is required for precision fit or vibration resistance. The 1\/2-20 UNF thread pitch provides tighter thread engagement than coarse-thread equivalents, making it a common choice in machine components, jigs, fixtures, and industrial equipment. The black oxide finish offers mild corrosion resistance and reduces light reflection on finished assemblies. Sold individually, with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile seats flush in standard countersunk holes\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch hex socket drive for secure torque application with standard Allen keys or hex bits\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 UNF thread provides fine-pitch engagement for precision and vibration-resistant installations\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the entire 1-1\/4-inch overall length\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low surface reflectivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in countersunk applications requiring a 1\/2-20 UNF fully threaded flat socket cap screw conforming to ASME\/ANSI B18.3 and ASTM F835 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 5\/16-inch hex key or hex socket bit. The mating hole must be properly countersunk to an 82-degree included angle to allow the flat head to seat flush. Ensure threads in the receiving material are clean and free of debris before driving. Do not exceed the torque capacity of the alloy steel fastener or the receiving material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1-1\/4 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: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 0.02 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: 211311PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695004352818,"sku":"211311PR","price":1309.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b5b648f6d76c5cf931965d39a0e0673.jpg?v=1788330411","url":"https:\/\/voomisupply.com\/products\/value-collection-211311pr-flat-socket-cap-screw-1-2-20","provider":"Voomi Supply","version":"1.0","type":"link"}
