It features an 82-degree flat head driven by a 5\/32-inch hex socket and is fully threaded along its 3\/4-inch overall length. Manufactured from alloy steel with a black oxide finish, it delivers solid mechanical strength alongside moderate corrosion resistance. This fastener meets ASME\/ANSI B18.3 and ASTM F835 standards. It is suited for use by machinists, millwrights, maintenance technicians, and other trade professionals working with precision assemblies or structural fixtures where a low-profile head is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for use in machine assemblies, jigs and fixtures, tooling plates, and general mechanical fabrication where a flush-mount fastener is needed. The 1\/4-28 UNF thread pitch makes it a fine-thread fastener, offering improved thread engagement and resistance to loosening under vibration compared to coarse-thread equivalents. It is commonly used in light industrial, automotive, and mechanical maintenance settings. The black oxide finish blends well in applications where fastener visibility is a concern. Sold individually, with a minimum order quantity of 100 units.\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 low-profile installation\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive for use with standard Allen or hex key sets\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF fine-thread designation for improved vibration resistance and thread engagement\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the entire 3\/4-inch length for maximum fastening flexibility\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 protection and a dark, low-reflectance appearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series flat socket cap screw compatible with any 1\/4-28 UNF tapped hole requiring an 82-degree countersunk head per ASME\/ANSI B18.3 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 5\/32-inch hex key or Allen driver. Ensure the mating countersink is machined to an 82-degree included angle to achieve proper head seating and load distribution. Verify the tapped hole thread form is UNF before installation to avoid cross-threading. Always torque to values appropriate for the alloy steel grade and joint material, referencing published fastener torque tables for 1\/4-28 UNF screws.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3\/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\/32 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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\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: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: 211127PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720990982450,"sku":"211127PR","price":1960.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8c6660fabdb8495bae1127d6479b537.jpg?v=1788571963","url":"https:\/\/voomisupply.com\/products\/value-collection-211127pr-flat-socket-cap-screw-1-4-28","provider":"Voomi Supply","version":"1.0","type":"link"}
