Threaded 5-40 UNC with an overall length of 1\/8 inch, this fastener is driven by a 1\/16 inch hex key and seats with a cup point that bites into the mating surface to resist rotation and axial movement. Manufactured from Grade 8 alloy steel, it meets ASME\/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians use this type of fastener to lock collars, hubs, pulleys, and shafts in precision assemblies.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for light-duty mechanical and electrical applications requiring a small-diameter, fine-pitch fastener. Typical uses include set screw collars, motor shaft retention, small gear hubs, and instrument assemblies where a No. 5-40 thread is specified. The cup point provides a positive bite without requiring a through-hole, making it practical for components that must be repositioned during service. Grade 8 alloy steel construction supports use in applications where higher hardness and shear resistance are required compared to standard steel fasteners.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-40 UNC thread with 1\/8 inch overall length for compact, flush-mount fastening\u003c\/li\u003e\n  \u003cli\u003eCup point geometry bites into mating surface to resist rotation and axial load\u003c\/li\u003e\n  \u003cli\u003e1\/16 inch hex drive for use with standard hex keys in confined spaces\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for elevated hardness and shear resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or stock fastener for mechanical assemblies specifying a No. 5-40 UNC cup point set screw with a 1\/16 inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 1\/16 inch hex key. Ensure the mating shaft or bore surface is clean and free of burrs before seating the cup point. De-energize or lock out any rotating equipment per applicable LOTO procedures before installing or removing set screws. Do not exceed the fastener thread engagement depth, and avoid over-torquing small-diameter set screws to prevent thread stripping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1\/8 inch (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: 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: 1\/16 inch (0.0625 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\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\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 101109PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693636092210,"sku":"101109PR","price":1302.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/449832835a421b4c3fc00b91d84ec71c.jpg?v=1788315282","url":"https:\/\/voomisupply.com\/products\/value-collection-101109pr-set-screw-5-40-x-1-8-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
