This fully threaded fastener measures 5\/16-18 thread size with a 5\/8-inch length under head and features a Torx Plus IP40 drive recess. The black oxide finish provides mild corrosion resistance and reduces surface glare. Hardness is rated at 39-44 HRC per ASTM F835, making this screw suitable for medium-to-high clamping force assemblies. It is installed by machinists, millwrights, maintenance technicians, and field service professionals across industrial, mechanical, and equipment fabrication settings.\u003c\/p\u003e\n\u003cp\u003eThis button cap screw is used in machine assemblies, equipment panels, fixtures, and mechanical enclosures where a domed low-profile head is preferred over a flat or hex head. The 5\/16-18 UNC thread form and Class 3A thread fit make it compatible with standard tapped holes in ferrous and non-ferrous assemblies. Typical applications include securing guards, brackets, and housings in light to medium industrial machinery. The black oxide finish is common in applications where a non-reflective surface finish is preferred and moderate indoor corrosion resistance is acceptable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTorx Plus IP40 drive reduces cam-out and allows higher torque transfer compared to standard hex socket drives\u003c\/li\u003e\n  \u003cli\u003eButton head profile provides a low-profile, rounded top surface suitable for flush or near-flush installations\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with 39-44 HRC hardness per ASTM F835 for reliable clamping strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating offers mild corrosion resistance and a non-reflective matte finish\u003c\/li\u003e\n  \u003cli\u003eFully threaded 5\/16-18 UNC right-hand thread with Class 3A fit for consistent engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI\/ASME B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or new-installation fastener for any 5\/16-18 UNC tapped hole requiring a button socket cap screw per ANSI\/ASME B18.3 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a Torx Plus IP40 driver bit. Ensure the mating tapped hole is clean, properly sized, and free of debris before driving. Do not exceed the torque rating appropriate for the alloy steel grade and thread engagement depth of the specific assembly. Black oxide finish is not a substitute for plated or coated fasteners in wet or outdoor environments where extended corrosion resistance is required.\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\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\u003eHead Type\u003c\/strong\u003e: Button\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Torx Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorx Drive Size\u003c\/strong\u003e: IP40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNRC\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\u003eHead Height\u003c\/strong\u003e: 0.166 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 39-44 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI\/ASME B18.3, ASTM F835\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: 353-0510-01\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721857728818,"sku":"353-0510-01","price":2680.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b023c0e3aea59a228c62d6fd0e72f465.jpg?v=1788582047","url":"https:\/\/voomisupply.com\/products\/value-collection-353-0510-01-button-socket-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
