It features an 82-degree flat head driven by a 5\/32-inch hex socket and is manufactured from alloy steel with a black oxide finish for moderate corrosion resistance. The 1\/4-20 UNC thread and 3-1\/2-inch overall length make it suited to medium-depth fastening tasks. This fastener is partially threaded, which helps maintain clamping force across thicker material stacks. Machinists, millwrights, and maintenance technicians install this type of screw in machinery, fixtures, and structural assemblies where a low-profile head is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in general industrial, manufacturing, and maintenance applications where the fastener head must sit flush with or below the surface of the mating material. Typical installation scenarios include machine frames, jigs, tooling plates, and mechanical assemblies that call for a countersunk hole pattern. The black oxide finish suits indoor and light-duty environments where moderate surface protection is acceptable. This screw conforms to ASME\/ANSI B18.3 and ASTM F835 standards, making it appropriate for applications governed by those fastener specifications.\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\/32-inch hex socket drive for precise torque application with standard Allen keys\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile strength for mechanical fastening\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish adds surface protection and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank maintains clamp load across thicker material joints\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use flat socket cap screw for industrial, manufacturing, and maintenance applications requiring a 1\/4-20 UNC countersunk fastener in alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a 5\/32-inch hex key or socket driver. De-energize and lock out any machinery before fastener installation or replacement per applicable OSHA lockout\/tagout procedures. Ensure the mating hole is countersunk to the correct 82-degree angle to achieve full head seating. Do not exceed the rated torque range for a 1\/4-20 alloy steel fastener as specified by the applicable engineering standard for the assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3-1\/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: 5\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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 and 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\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: 721152PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720528003378,"sku":"721152PR","price":1155.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_43857ede-d15e-4c0d-b148-31c2b076e948.jpg?v=1788565578","url":"https:\/\/voomisupply.com\/products\/value-collection-721152pr-flat-socket-cap-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
