Set screws are fully threaded fasteners with no head, designed to secure a component — such as a pulley, gear, or collar — onto a shaft by direct contact pressure. The cup point bites into the shaft surface to resist rotation and axial movement. Driven with a 1\/8-inch hex key, this fastener meets ASME\/ANSI B18.3 and ASTM F912 standards. It is commonly installed by millwrights, maintenance technicians, and mechanical contractors in a wide range of industrial and commercial equipment assemblies.\u003c\/p\u003e\u003cp\u003eCup point set screws in the 1\/4-20 thread size are widely used in light to medium-duty shaft-locking applications across HVAC equipment, pumps, fans, motors, and general mechanical assemblies. The UNC\/UNF-compatible threading and fractional-inch sizing make this fastener a standard choice for domestic machinery and equipment manufactured to inch-dimensioned specifications. Grade 8 alloy steel construction provides the hardness and tensile strength needed to hold under vibration and rotational load in demanding service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCup point geometry bites into shaft surface for secure, vibration-resistant locking\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high tensile strength and hardness\u003c\/li\u003e\n\u003cli\u003e1\/8-inch hex drive for use with standard Allen or hex key wrenches\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 fastener standards\u003c\/li\u003e\n\u003cli\u003eUNC\/UNF thread standard compatibility for broad domestic equipment fitment\u003c\/li\u003e\n\u003cli\u003eFractional inch sizing for use in inch-dimensioned mechanical assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-20 UNC\/UNF cup point set screw suitable for use in any application requiring a headless shaft-locking fastener in this thread size and length per ASME\/ANSI B18.3 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSet screws should be installed by qualified mechanical or maintenance technicians. De-energize and lock out all rotating equipment before installation or removal. Use a properly sized 1\/8-inch hex key to avoid rounding the drive socket. Apply thread-locking compound if vibration is expected to cause loosening over time.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1\/2 inches (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\/8 inches (0.1250 inches)\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 \/ 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: 0.00431 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\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: 101317P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702209544498,"sku":"101317P","price":2931.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78938927a8e0cdceb8ce0dbb2c5b4472.jpg?v=1788409966","url":"https:\/\/voomisupply.com\/products\/value-collection-101317p-set-screw-1-4-20-x-1-2-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
