Sized at 1\/4-28 UNF with a 3-inch length under head, this screw is partially threaded and driven by a 3\/16-inch hex key. It is manufactured from 18-8 austenitic stainless steel (Grade A2), offering good corrosion resistance in moderate environments. Trades commonly used in HVAC, plumbing, electrical, and general mechanical assembly rely on socket cap screws like this for tight-clearance installations where a wrench-access limitation rules out external hex fasteners.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light industrial and commercial mechanical assemblies, equipment panel mounting, bracket attachment, and maintenance applications where stainless steel corrosion resistance is required. The fine 1\/4-28 UNF thread pitch provides stronger clamp load and better vibration resistance compared to coarse-thread equivalents of the same diameter, making it appropriate for metal-to-metal joints and precision mechanical components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF fine thread for higher clamp load and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head accommodates moderate material stack thickness\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for use with standard Allen or hex key tools\u003c\/li\u003e\n  \u003cli\u003e18-8 austenitic stainless steel (Grade A2) provides corrosion resistance in moderate-humidity environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows for precise shoulder-bearing load in bolted joints\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F837 fastener standards\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 mechanical assemblies, equipment frames, and maintenance applications calling for an 18-8 stainless steel fastener to ASME\/ANSI B18.3 dimensions.\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; use of a torque wrench with a hex bit is recommended in critical joints. Ensure mating threads are clean and free of debris before fastening. In stainless-to-stainless assemblies, apply an appropriate anti-galling lubricant to prevent thread seizure during installation. Always follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.\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: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8 Austenitic Grade A2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM F837\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: 592285PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714348417330,"sku":"592285PR","price":1610.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c9a2a0009891924a2ca223b5da382b3_a7f4b567-a008-4cc9-a746-fcfae5e619fa.jpg?v=1788499973","url":"https:\/\/voomisupply.com\/products\/value-collection-592285pr-hex-socket-cap-screw-1-4-28-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
