Set screws are headless fasteners used to secure a component — such as a collar, gear, or pulley — against or onto a shaft by applying direct pressure at the point of contact. This screw uses a 5\/32 inches hex (Allen) drive and a flat point tip, which distributes clamping force across a broader contact area without marring the mating surface. It meets ASME\/ANSI B18.3 and ASTM F912 standards, making it suitable for precision mechanical assemblies where dimensional and strength consistency are required.\u003c\/p\u003e\n\u003cp\u003eFlat point set screws like the 151256PR are commonly used in light to medium industrial assemblies, HVAC equipment, pump and motor shaft collars, and other mechanical drive components. The Grade 8 alloy steel construction provides high tensile strength suitable for applications involving vibration or sustained clamping load. Maintenance technicians, millwrights, and mechanical contractors working on rotating equipment or adjustable shaft-mounted components are the typical installers of this fastener. The UNC 5\/16-18 thread pitch is a standard coarse-thread designation widely found in American mechanical hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile strength and durability\u003c\/li\u003e\n  \u003cli\u003eFlat point tip distributes clamping force without damaging the mating shaft surface\u003c\/li\u003e\n  \u003cli\u003e5\/32 inches hex (Allen) drive for precise torque application in tight clearances\u003c\/li\u003e\n  \u003cli\u003eUNC 5\/16-18 coarse thread standard for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and performance standards\u003c\/li\u003e\n  \u003cli\u003eHeadless design allows full recessing below the surface of the host component\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC coarse-thread set screw for use in any tapped 5\/16-18 hole requiring a flat point, headless fastener in light to medium mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 5\/32 inches hex key or Allen driver. Ensure the tapped receiving hole is clean and free of debris before threading. De-energize and lock out any rotating equipment before installing or adjusting set screws on shaft-mounted components. Do not exceed the torque rating appropriate for Grade 8 alloy steel at this thread size, and verify thread engagement depth meets the requirements of the assembly design.\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\u003c\/strong\u003e: 5\/16 inches (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex (Allen)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 5\/32 inches (0.1563 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F912\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\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: 151256PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695066054962,"sku":"151256PR","price":3238.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf2af5d128927f71f09e300b23705b0a.jpg?v=1788331006","url":"https:\/\/voomisupply.com\/products\/value-collection-151256pr-set-screw-5-16-18-x-5-16-in-flat-point","provider":"Voomi Supply","version":"1.0","type":"link"}
