This fastener features a 1\/4-28 UNF thread — a fine-pitch designation suited for assemblies where vibration resistance and precise thread engagement matter. The screw is fully threaded along its 3\/4-inch length under head, providing maximum thread engagement in thin materials or shallow blind holes. Constructed from alloy steel with a zinc-plated finish, it delivers solid mechanical strength with basic corrosion resistance for general industrial and mechanical use. Drive size is 3\/16 inch hex socket.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in a wide range of light-to-medium industrial, mechanical, and maintenance applications where a socket-drive cap screw is specified. The 1\/4-28 UNF fine thread makes it appropriate for metal-to-metal assemblies, machine components, brackets, and fixtures where standard coarse-thread fasteners would not meet the specification. It is installed by maintenance technicians, machinists, and trade professionals using a 3\/16-inch hex key or Allen driver. The zinc-plated finish provides a baseline level of corrosion protection in dry or mildly humid indoor environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF fine thread for vibration-resistant, precise thread engagement\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank maximizes thread engagement in shallow or thin-material applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for solid tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides baseline corrosion protection\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for use with standard Allen keys or hex drivers\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM B695 fastener standard\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 suitable for general-purpose mechanical and industrial assemblies requiring this thread specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/16-inch hex key or hex socket driver. Ensure mating threads are clean and free of debris before installation. De-energize or lock out any equipment before fastener service on live assemblies per applicable safety standards. Do not exceed the rated load for the fastener grade or substitute this fine-thread screw into applications specifying coarse-thread (UNC) fasteners without engineering review.\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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: ASTM B695\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: 837177PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722980819250,"sku":"837177PR","price":6520.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c9a2a0009891924a2ca223b5da382b3_b21806c1-7c2c-476b-8b32-d3140be2c3df.jpg?v=1788598796","url":"https:\/\/voomisupply.com\/products\/value-collection-837177pr-hex-socket-cap-screw-1-4-28-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
