The screw features a 5\/16-inch hex socket drive and is manufactured from 18-8 stainless steel with a bright, uncoated finish. It carries a 1\/2-13 UNC thread designation, meaning 1\/2-inch nominal diameter with 13 threads per inch, and a 1-1\/2-inch length under the head. The head height measures 0.265 inches. Thread fit is Class 3A, indicating a standard external thread tolerance for general mechanical assembly. This fastener conforms to ANSI\/ASME B18.3 standards and is suited for installation by maintenance technicians, millwrights, and mechanical contractors.\u003c\/p\u003e\u003cp\u003eThis button socket cap screw is appropriate for light to medium-duty mechanical assemblies where a rounded, low-profile head reduces snagging risk or where clearance is limited. Common applications include equipment panels, enclosure hardware, machine guards, brackets, and structural assemblies exposed to moisture or mild corrosion risk. The 18-8 stainless steel construction makes it a practical choice for indoor and outdoor environments where corrosion resistance is a factor. The right-hand UNC thread direction is standard for the majority of mechanical assembly work across commercial and industrial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLow-profile button head reduces protrusion in tight-clearance assemblies\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments\u003c\/li\u003e\n\u003cli\u003e5\/16-inch hex socket drive for use with standard Allen keys or hex socket bits\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC Class 3A thread fit for reliable engagement with standard UNC nuts and tapped holes\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI\/ASME B18.3 fastener standard\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating to flake, chip, or affect thread fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC replacement or new-installation fastener compatible with any 1\/2-13 tapped hole or nut conforming to ANSI\/ASME B18.3 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 5\/16-inch hex key or hex socket driver. Power down or de-energize any equipment before accessing fastener points on live systems. Stainless steel fasteners are susceptible to galling during installation — apply an appropriate anti-seize compound and install at moderate speed to prevent thread damage. Follow applicable mechanical codes and equipment manufacturer torque guidance for the specific assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 3A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.265 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: 5\/16 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI\/ASME B18.3\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: R63062363\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717141922098,"sku":"R63062363","price":915.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f72640247fe2d5c884e451c6a778069.jpg?v=1788536205","url":"https:\/\/voomisupply.com\/products\/value-collection-r63062363-button-socket-cap-screw-1-2-13","provider":"Voomi Supply","version":"1.0","type":"link"}
