Manufactured from alloy steel with a black oxide coating, this fastener measures 2.5 inches in length under the head and uses a 1\/4-inch hex drive. The partial thread pattern is typical for longer cap screws, allowing the unthreaded shank to bear shear loads while the threaded portion engages the mating material. It meets ASME\/ANSI B18.3 and ASTM A574 standards, confirming dimensional accuracy and tensile strength requirements. Machinists, maintenance technicians, and industrial assembly professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in general industrial machinery, tooling fixtures, equipment housings, and fabricated assemblies where a recessed drive is preferred over an external hex. The 5\/16-18 UNC thread is a common coarse-thread specification found in a wide range of steel and cast-iron components. The black oxide finish provides mild corrosion resistance and reduces light reflection in precision assemblies. The partial threading is appropriate for applications requiring a grip length through clearance holes or stacked components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e2.5-inch length under head with partial threading for shear-load and grip-length applications\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex socket drive for use with standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meeting ASTM A574 high-strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion resistance and a low-glare finish\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in any application requiring a 5\/16-18 UNC partially threaded fastener with a 1\/4-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 1\/4-inch hex key or socket bit driver; ensure the drive tool is fully seated to avoid rounding the socket. Always verify the tapped hole thread spec and depth before installation. Torque to the fastener manufacturer or equipment OEM specification for the applicable material and joint condition. Inspect the black oxide coating for damage before installation in corrosive environments, as black oxide alone provides limited protection without supplemental lubrication or sealant.\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: 2.5 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\u003eStandards\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.057 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 011215P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723182473522,"sku":"011215P","price":9768.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac9097cb3e23d2cbf37741cbc07c58d2.jpg?v=1788601703","url":"https:\/\/voomisupply.com\/products\/value-collection-011215p-hex-socket-cap-screw-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
