Driven by a 5\/64 inch hex key, this headless fastener seats flush or below the surface of the mating part, allowing shafts, collars, and pulleys to be locked in position without protruding hardware. Manufactured to Grade 8 alloy steel and conforming to ASME\/ANSI B18.3 and ASTM F912 standards, it delivers the hardness and tensile strength required in demanding industrial and mechanical service environments. The knurled cup point bites into the mating surface to resist rotational and axial movement under load.\u003c\/p\u003e\n\u003cp\u003eThis set screw is used across a wide range of mechanical and trade applications including HVAC blower wheel collar retention, motor shaft locking, pulley and gear positioning, and general machine assembly. It is suited for residential and light commercial equipment where a compact, flush-fastening solution is required. The 8-32 UNC thread is a common size found in small-bore collars and hubs throughout industrial and building-trades equipment. Minimum order quantity is 100 pieces, making this part appropriate for shop stock, service van inventory, or production use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKnurled cup point bites into mating surfaces to resist axial and rotational slip under load\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high hardness and tensile strength\u003c\/li\u003e\n  \u003cli\u003eHeadless design allows flush or sub-flush installation in collars, hubs, and pulleys\u003c\/li\u003e\n  \u003cli\u003e5\/64 inch hex drive compatible with standard hex keys and L-wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003e8-32 UNC thread is a widely stocked size for small mechanical assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 8-32 UNC set screw for use in any collar, hub, pulley, or mechanical assembly requiring a headless fastener with a knurled cup point and 5\/64 inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 5\/64 inch hex key or L-wrench; ensure the key is fully seated in the drive socket before applying torque to avoid rounding. Power down or de-energize any associated equipment before servicing fasteners on rotating components such as blower wheels or motor shafts. Thread engagement and seating should be verified after initial installation and after the assembly has been returned to service for the first time. Alloy steel set screws should not be used in direct contact with stainless or dissimilar metals in corrosive environments without appropriate consideration for galvanic compatibility.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1\/4 inches (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\/64 inches (0.0781 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: 111136PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694156251442,"sku":"111136PR","price":1323.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/15ef0e21fbfcc94b9b446f8ee30e7e56.jpg?v=1788321005","url":"https:\/\/voomisupply.com\/products\/value-collection-111136pr-set-screw-8-32-x-1-4-in-knurled-cup","provider":"Voomi Supply","version":"1.0","type":"link"}
