Manufactured from 18-8 stainless steel with a bright, uncoated finish, this screw delivers solid corrosion resistance in both indoor and outdoor environments. The fully threaded, 2-inch length under head provides consistent grip across the full fastener shank. Thread fit class 3A ensures a precise, controlled fit with standard UNC nuts and tapped holes. This fastener is installed using a 3\/16-inch hex socket key and is commonly used by mechanical contractors, millwrights, equipment fabricators, and maintenance technicians across a range of industrial and commercial applications.\u003c\/p\u003e\u003cp\u003eThis button socket cap screw suits applications where a standard hex cap head would interfere with adjacent components or where a smoother, rounded head profile is required. Typical use cases include machinery guards, enclosures, sheet metal assemblies, brackets, and light structural connections. The right-hand thread direction and UNC thread standard make this screw compatible with the most commonly available tapped holes and hex nuts in North American trade work. Sold individually with a minimum order quantity of 50 pieces per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLow-profile button head reduces interference in tight clearance assemblies\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel construction provides corrosion resistance without surface coating\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex socket drive for reliable torque transfer with standard Allen keys or hex bit drivers\u003c\/li\u003e\n\u003cli\u003eFully threaded 2-inch shank for maximum thread engagement across the fastener length\u003c\/li\u003e\n\u003cli\u003eThread fit class 3A meets ANSI\/ASME B18.3 and ASTM F837 fastener standards\u003c\/li\u003e\n\u003cli\u003eRight-hand UNC thread matches standard North American tapped holes and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 5\/16-18 UNC tapped holes and hex nuts conforming to ANSI\/ASME B18.3 specifications.

Confirm the tapped hole thread standard is UNC before installation to avoid cross-threading. De-energize and lock out any equipment before accessing fastener locations on live machinery, following applicable OSHA lockout\/tagout procedures. Do not exceed the fastener's rated load by substituting this screw in structural applications for which it was not specified.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 3A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 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: 0.166 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: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 18-8 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Coverage\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI\/ASME B18.3; ASTM F837\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 93129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723229331762,"sku":"93129","price":60.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7882ab9ff81eca69ea92f90e0184bd0d.jpg?v=1788602088","url":"https:\/\/voomisupply.com\/products\/value-collection-93129-button-socket-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
