Sized at 5\/16-18 UNC thread with a 5\/8-inch length under the head, this screw is fully threaded and driven by a 3\/16-inch hex socket. The black oxide coating provides mild corrosion resistance and reduces light reflection on installed assemblies. Hardness is rated at 36-43 HRC, meeting the requirements of ANSI\/ASME B18.3 and ASTM F835. Machinists, millwrights, and mechanical assembly technicians are the primary installers of this fastener.\u003c\/p\u003e\n\u003cp\u003eThis button socket cap screw suits general mechanical assembly, machine guarding, fixture building, and equipment fabrication where a flush or semi-flush head profile is preferred over a standard hex socket cap head. The low-dome button head distributes clamping load over a wider bearing surface and sits closer to the workpiece face. It is appropriate for both ferrous and non-ferrous base materials in light to medium clamping applications. Minimum order quantity is 100 pieces per order; package quantity is 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLow-profile button head for flush or near-flush installations\u003c\/li\u003e\n  \u003cli\u003eFully threaded 5\/16-18 UNC right-hand thread, Thread Fit Class 3A\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for standard Allen wrenches and hex-bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with 36-43 HRC hardness per ASTM F835\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced surface glare\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 5\/16-18 UNC button socket cap screw per ANSI\/ASME B18.3 and ASTM F835, suitable for use in any application calling for this thread size and head style.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical assembly technicians using a 3\/16-inch hex key or socket bit driver. Ensure mating threads are clean and free of debris before installation. Do not exceed the clamping load appropriate for 5\/16-18 alloy steel fasteners in the base material being used. Black oxide coating is not a heavy corrosion barrier; apply supplemental thread lubricant or sealant if the installation environment involves moisture exposure.\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\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: 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\u003eHead Height\u003c\/strong\u003e: 0.1660 inches\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\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 36-43 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: 0.01506 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 201135P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720847458610,"sku":"201135P","price":4698.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8ea5d32c1b080ec5d6332edb453ca48.jpg?v=1788569904","url":"https:\/\/voomisupply.com\/products\/value-collection-201135p-button-socket-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
