Set screws are headless fasteners used to secure a component — such as a collar, gear, or pulley — against or within another part by applying direct pressure or biting into a mating surface. The knurled cup point provides enhanced grip and resists loosening under vibration. Driven by a 5\/32-inch hex key, this fastener meets ASME\/ANSI B18.3 and ASTM F912 standards, making it appropriate for precision mechanical assemblies where holding force and dimensional consistency are critical.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for maintenance, repair, and fabrication work in industrial, mechanical, and trade settings. Common applications include shaft-to-hub connections, positioning collars on round stock, and securing sprockets or pulleys in drive assemblies. The UNF thread form (5\/16-24) provides finer thread engagement than coarse-thread equivalents, which is beneficial in thin-walled hubs or applications requiring precise axial adjustment. Machinists, millwrights, and maintenance technicians working on rotating equipment are the primary installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnurled cup point bites into mating surfaces for superior vibration resistance\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003e5\/16-24 UNF thread form for fine-pitch engagement and precise adjustment\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex drive compatible with standard hex keys and Allen wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1\/2 inch for compact installation in shallow hub applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-24 UNF set screw for use in any hub, collar, or mechanical assembly tapped to accept a 5\/16-24 thread with a 5\/32-inch hex drive socket.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or maintenance technician using a calibrated hex key or T-handle driver. De-energize and lock out any rotating equipment before installing or removing set screws. Ensure the tapped hole is clean and free of debris before threading the fastener. Do not overtighten — use a torque specification provided by the equipment manufacturer for the specific hub material and shaft diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1\/2 inch (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Knurled Cup\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 5\/32 inch (0.1563 inch)\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: UNF\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: 111345PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702578282802,"sku":"111345PR","price":2618.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed28e1bbb1c5f123bda325ba39e90bf8_4a7d62fe-4ef0-4012-b4a7-f9f234cc3b39.jpg?v=1788412076","url":"https:\/\/voomisupply.com\/products\/value-collection-111345pr-set-screw-5-16-24-x-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
