It features a 1\/4-28 UNF thread size with a 2-inch length under head and is partially threaded to maintain clamping force in standard bolt configurations. The 3\/16-inch hex drive accepts a standard Allen-style hex key. Constructed from alloy steel with a black oxide finish, this fastener resists corrosion in low-moisture environments and meets ASME\/ANSI B18.3 and ASTM A574 standards. Machinists, millwrights, and mechanical contractors use this fastener where precise threading and reliable torque retention are required.\u003c\/p\u003e\u003cp\u003eThis screw is suited for general industrial and mechanical maintenance applications requiring a fine-thread, high-strength cap screw. The 1\/4-28 UNF thread pitch provides finer thread engagement compared to coarse-thread equivalents, making it well-suited for thin-walled components, precision assemblies, and applications where vibration resistance is a priority. The black oxide alloy steel construction supports use in light-duty corrosion environments typical of indoor mechanical and electrical enclosures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-28 UNF fine thread for precise engagement and vibration resistance\u003c\/li\u003e\n\u003cli\u003e2-inch length under head, partially threaded for standard clamping applications\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex drive compatible with standard Allen keys and hex drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 high-strength fastener requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 socket cap screw standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in any application requiring a 1\/4-28 UNF partially threaded cap screw with a 3\/16-inch hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a calibrated 3\/16-inch hex key or hex driver bit. Ensure mating threads are clean and free of debris before installation. De-energize and lock out any equipment before fastener replacement or adjustment per applicable safety procedures. Do not exceed the torque rating specified in your assembly documentation for 1\/4-28 ASTM A574 fasteners.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 2 inches\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\u003eThreading\u003c\/strong\u003e: Partially 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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 011189P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690539647282,"sku":"011189P","price":4482.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b8cff88645657224e1f6c844e47cec0.jpg?v=1788271296","url":"https:\/\/voomisupply.com\/products\/value-collection-011189p-hex-socket-cap-screw-1-4-28-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
