It features an 82-degree flat head driven by a 5\/16-inch hex socket and is fully threaded along its 2-inch overall length. The 1\/2-20 UNF thread specification indicates a fine-thread pitch suited for precision assemblies where vibration resistance or tight tolerance fits are priorities. Manufactured from alloy steel with a black oxide finish, the screw offers solid mechanical strength and moderate corrosion resistance. This fastener is installed by machinists, millwrights, maintenance technicians, and mechanical contractors working on structural, mechanical, or equipment assemblies.\u003c\/p\u003e\u003cp\u003eThis screw is well suited for machine assembly, jig and fixture construction, tooling, and general mechanical fabrication where a low-profile head is required to sit flush with or below a mating surface. The fine 1\/2-20 UNF thread makes it appropriate for use in applications requiring precise thread engagement and controlled clamp load. It conforms to ASME\/ANSI B18.3 and ASTM F835 fastener standards, making it compatible with controlled-specification assembly environments in both light industrial and commercial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree flat head profile for flush or countersunk installations\u003c\/li\u003e\n\u003cli\u003e5\/16-inch hex socket drive for secure torque application\u003c\/li\u003e\n\u003cli\u003e1\/2-20 UNF fine-thread specification for vibration-resistant, precision assemblies\u003c\/li\u003e\n\u003cli\u003eFully threaded 2-inch overall length for maximum thread engagement\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction provides high tensile and shear strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion protection and reduces light reflectance\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-specification flat socket cap screw for use in any application requiring a 1\/2-20 UNF fully threaded countersunk fastener conforming to ASME\/ANSI B18.3 and ASTM F835.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 5\/16-inch hex key or socket driver rated for the applicable torque. Ensure the mating countersink is machined to an 82-degree included angle for proper head seating. Power down and de-energize any equipment before fastener removal or installation in live mechanical assemblies. Apply thread lubricant or thread-locking compound only as specified by the assembly engineering documentation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 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: 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\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 211317PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701693350194,"sku":"211317PR","price":1643.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_d1c22814-95c9-42e3-b999-8d52a09823e0.jpg?v=1788403870","url":"https:\/\/voomisupply.com\/products\/value-collection-211317pr-flat-socket-cap-screw-1-2-20x2","provider":"Voomi Supply","version":"1.0","type":"link"}
