Machined from alloy steel with a black oxide finish, this fastener measures 1\/4-28 UNF x 3\/4 inches in overall length and accepts a 5\/32-inch hex socket drive. The 82-degree flat head seats flush with the workpiece surface when installed in a properly countersunk hole. Alloy steel construction provides solid strength for mechanical assemblies, tooling fixtures, and equipment fabrication. The black oxide finish offers moderate corrosion resistance and reduces light reflection in precision setups. Licensed trades, machinists, and maintenance professionals install these in metal and composite assemblies where head clearance is limited.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in industrial machinery, mechanical assemblies, jigs, fixtures, and general equipment fabrication where a low-profile flush-mount fastener is needed. The 1\/4-28 UNF thread pitch is a fine-thread designation, making it appropriate for applications requiring tighter thread engagement, vibration resistance, or use in thinner materials. The fully threaded body ensures maximum thread engagement across the entire length of the fastener. Sold in packs of 25, this SKU is practical for shop stock, field service kits, and maintenance departments that regularly work with this fastener size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head seats flush when installed in a standard countersunk hole\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF fine-thread for tighter engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eFully threaded body maximizes thread engagement over the full 3\/4-inch length\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with black oxide finish for strength and moderate corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets 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 a standard replacement or stock fastener for applications requiring a 1\/4-28 UNF x 3\/4-inch 82-degree flat socket cap screw per ASME\/ANSI B18.3 and ASTM F835 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly sized countersunk hole to allow the 82-degree flat head to seat flush with the mating surface. Use a calibrated 5\/32-inch hex key or bit driver and tighten to the torque specification called out in the equipment service documentation. De-energize and lock out any machinery before replacing fasteners in live assemblies. Avoid cross-threading by starting the fastener by hand before applying drive torque.\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 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\u003eThread Standard\u003c\/strong\u003e: UNF\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\u003ePackage Quantity\u003c\/strong\u003e: 25 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: -36871-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701972959538,"sku":"-36871-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5baed1e5b28e992833e8a69a33decc2.jpg?v=1788407606","url":"https:\/\/voomisupply.com\/products\/value-collection-36871-2-flat-socket-cap-screw-1-4-28","provider":"Voomi Supply","version":"1.0","type":"link"}
