It carries a 1\/4-28 UNF thread size, a 1-1\/4 inch length under head, and is fully threaded. The 3\/16 inch hex drive accepts a standard hex key or Allen wrench. Constructed from alloy steel with a zinc-plated finish, this screw delivers solid mechanical strength and basic corrosion resistance for indoor and light-duty industrial environments. It meets ASME B18.8 and ASTM A574 standards, making it suitable for precision and structural fastening tasks.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in mechanical assemblies, fixtures, and fabricated components where a recessed hex drive is preferred over an external hex head. The fine 1\/4-28 UNF thread pitch provides greater thread engagement per inch compared to coarse thread, making it well suited for thin-material applications, vibration-prone assemblies, and situations where precise torque adjustment is needed. It is commonly installed by machinists, millwrights, and maintenance technicians in manufacturing, HVAC equipment assembly, and general industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF fine thread for high thread engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded 1-1\/4 inch length under head for maximum grip across material thickness\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex socket drive compatible with standard hex keys and T-handle drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion protection for indoor and sheltered use\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.8 dimensional standards for consistent fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and general-purpose replacement hex socket cap screw for assemblies requiring a 1\/4-28 UNF fully threaded fastener with a 3\/16 inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 3\/16 inch hex key or Allen driver. Ensure the mating threaded hole is clean and free of debris before driving the screw. Avoid over-torquing, which can strip the fine UNF threads or damage the zinc coating. Follow applicable industry torque guidelines for 1\/4-28 alloy steel fasteners in the relevant assembly context.\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 Under Head\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\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: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.8, ASTM A574\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: 872183PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694755283250,"sku":"872183PR","price":5740.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2573ecc6a34f739685f234b944db5a67.jpg?v=1788328084","url":"https:\/\/voomisupply.com\/products\/value-collection-872183pr-hex-socket-cap-screw-1-4-28-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
