Manufactured from alloy steel with a zinc-plated finish, this fastener measures 5\/8 inches in length under the head and is fully threaded along its entire shank. The 3\/16-inch hex drive accepts a standard Allen wrench or hex bit driver. It meets ASME B18.8 and ASTM A574 standards, making it appropriate for mechanical assemblies, HVAC equipment mounting, panel hardware, and general industrial fastening tasks performed by technicians across multiple trades.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light to medium-duty fastening in residential and commercial mechanical systems. Common applications include securing access panels, component brackets, blower housings, and equipment frames where a recessed hex drive is specified. The 1\/4-28 UNF fine thread provides tighter thread engagement per inch compared to coarse thread equivalents, which is an advantage in metal-to-metal joints where vibration resistance or precise torque control is required. Sold in a minimum order quantity of 100 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlloy steel construction with zinc-plated coating for corrosion resistance in typical indoor mechanical environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF fine thread for positive thread engagement in metal components\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank along the full 5\/8-inch length under the head\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive compatible with standard Allen wrenches and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.8 and ASTM A574 dimensional and mechanical property standards\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 100 pieces supports bulk stocking for service vehicles and shop inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-28 UNF hex socket cap screw for use in any mechanical assembly or equipment that specifies this thread size, drive type, and length under the head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 3\/16-inch hex key or Allen-style driver; ensure the correct drive size is used to avoid rounding the socket. De-energize or lock out equipment before accessing any fastened panels or components per NFPA 70E and site-specific lockout\/tagout procedures. Do not exceed the torque specification for 1\/4-28 alloy steel fasteners as outlined in the applicable equipment service documentation. Zinc-plated fasteners are intended for dry or mildly humid indoor environments and are not rated for prolonged outdoor or high-moisture exposure.\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: 5\/8 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: 872175PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691674861874,"sku":"872175PR","price":2272.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef6720c757834135ee8af4c7b0630447_d10e211b-5ded-4702-b8c7-e2765526dc9e.jpg?v=1788288316","url":"https:\/\/voomisupply.com\/products\/value-collection-872175pr-hex-socket-cap-screw-1-4-28-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
