Built from 18-8 austenitic stainless steel with a black oxide coating, this cap screw delivers corrosion resistance with a low-reflectance finish. The 2-3\/4 inch length under head and 1\/4 inch hex socket drive make it compatible with standard Allen keys and hex drivers. It is partially threaded, which provides stronger clamping force in metal-to-metal joints. Maintenance technicians, millwrights, and equipment assemblers working in corrosive or high-humidity environments will find this fastener well-suited to demanding service conditions.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in general industrial, mechanical, and HVAC equipment assemblies where a flush or recessed drive head is required. The socket cap head allows installation in tight clearances where a traditional hex bolt head would interfere. Partial threading makes it appropriate for through-bolted joints requiring precise clamping without thread engagement across the full grip length. It is sold in a minimum order quantity of 5 pieces per transaction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread size with partial threading for strong metal-to-metal clamping\u003c\/li\u003e\n  \u003cli\u003e2-3\/4 inch length under head for deep grip applications\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex socket drive compatible with standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003e18-8 austenitic stainless steel (Material Grade A2) for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating reduces glare and provides mild additional surface protection\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 UNC hex socket cap screw for use in any assembly requiring a 5\/16-18 thread and a 1\/4 inch hex socket drive, conforming to ASME\/ANSI B18.3 dimensional standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 1\/4 inch hex key or hex bit driver. Ensure mating threads are clean and free of debris before driving to prevent cross-threading. Power down or de-energize any equipment before accessing fastened assemblies in electrical or mechanical panels. Do not mix stainless steel fasteners with dissimilar metals in environments where galvanic corrosion is a concern without appropriate isolation measures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Socket Cap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/4 inch\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\u003eFinish Coating\u003c\/strong\u003e: Black Oxide\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 592289PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712053182770,"sku":"592289PR","price":1341.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c9a2a0009891924a2ca223b5da382b3_b802359d-5039-474d-8e04-ae6e6f6ca1a3.jpg?v=1788483082","url":"https:\/\/voomisupply.com\/products\/value-collection-592289pr-5-16-18-socket-cap-screw-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
