Sized at 5\/16-18 (UNC) thread with a 1\/2-inch length under the head, it is fully threaded and driven with a 3\/16-inch hex socket. Constructed from alloy steel with a black oxide finish, this screw meets ANSI\/ASME B18.3 and ASTM F835 standards. A hardness rating of 36-43 HRC gives it the strength needed for demanding mechanical assemblies. It is suited for use by machinists, millwrights, maintenance technicians, and general mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in a wide range of industrial and mechanical applications where a standard hex cap screw head would protrude too far or interfere with adjacent components. The button head profile distributes clamping load across a wider bearing surface than a flat head, making it a common choice in machine frames, guards, fixtures, and equipment panels. It is installed in both light manufacturing and heavy industrial environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButton head, low-profile design reduces interference with surrounding components\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 hex keys or socket drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with black oxide coating for corrosion resistance and reduced light reflection\u003c\/li\u003e\n  \u003cli\u003eHardness rated 36-43 HRC for high-strength fastening applications\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI\/ASME B18.3 and ASTM F835 dimensional and mechanical standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and general-use replacement or supplemental fastener for any assembly requiring a 5\/16-18 UNC fully threaded button socket cap screw with a 1\/2-inch grip length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, maintenance technicians, or mechanical contractors using a 3\/16-inch hex key or bit driver. Verify the mating threaded hole is clean and free of debris before installation. Do not exceed the rated hardness range of the fastener by using impact tools without appropriate torque control. Refer to applicable ANSI\/ASME standards for recommended torque values based on thread size and application.\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\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: 0.5 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: 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: 0.013 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: 201133P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717311201586,"sku":"201133P","price":4447.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de371d11af5931129a291d6bc0fae5fc.jpg?v=1788538308","url":"https:\/\/voomisupply.com\/products\/value-collection-201133p-button-socket-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
