This screw features a 5\/16-18 UNC thread size, a 3-1\/2-inch length under head, and a 1\/4-inch hex drive socket. It is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces light glare on the fastener surface. Partially threaded along its shank, it is suited for applications where clamping force and shear load distribution are priorities. Machinists, millwrights, and maintenance technicians are the typical installers.\u003c\/p\u003e\u003cp\u003eThis fastener is appropriate for use in both light industrial and heavy-duty mechanical applications where a recessed hex drive is required for torquing in confined spaces or flush-mount installations. The 5\/16-18 UNC coarse thread pattern offers reliable thread engagement in steel, cast iron, and aluminum tapped holes. It is commonly used in machine frames, jigs, fixtures, and equipment panels across manufacturing and maintenance environments. Minimum order quantity is 5 units; package quantity is 1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC coarse thread for reliable engagement in standard tapped holes\u003c\/li\u003e\n\u003cli\u003e3-1\/2-inch length under head accommodates deeper fastening requirements\u003c\/li\u003e\n\u003cli\u003e1\/4-inch hex socket drive allows use of standard Allen keys and hex bit drivers\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides improved shear strength and clamping performance\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction delivers high tensile and yield strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish offers mild corrosion resistance and a low-reflectance surface\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3, ASTM A574, and IFI 124 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or specification fastener for any application requiring a 5\/16-18 UNC hex socket cap screw with a 3-1\/2-inch length under head and 1\/4-inch drive, conforming to ASME\/ANSI B18.3 dimensional standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 1\/4-inch hex key or hex bit driver. Ensure the receiving threaded hole is clean, properly tapped to 5\/16-18 UNC, and free of debris before driving the fastener. Apply thread lubricant or thread-locking compound as required by the assembly specification. Do not exceed the rated torque for the thread size and material combination as defined in applicable fastener standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 3-1\/2 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: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574, IFI 124\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 015223PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696632693042,"sku":"015223PR","price":1071.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5949f36969499ab06d103947aaee7f1a.jpg?v=1788344675","url":"https:\/\/voomisupply.com\/products\/value-collection-015223pr-hex-socket-cap-screw-5-16-18","provider":"Voomi Supply","version":"1.0","type":"link"}
