Set screws are fully threaded fasteners with no head — they seat flush or below the surface of the work piece to lock a shaft, collar, or hub in position. The cup point configuration bites into the mating surface to resist rotational and axial movement under load. Drive is a 1\/4 inch hex socket. This fastener meets ASME\/ANSI B18.3 and ASTM F912 standards and is installed by machinists, millwrights, and maintenance technicians across industrial and mechanical applications.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for shaft-to-hub assemblies, shaft collars, sprockets, pulleys, and similar mechanical connections where a flush-mounted locking fastener is required. The 1\/2-20 fine thread pitch provides precise torque control and holding strength in applications where vibration resistance and positional accuracy matter. Overall length is 3\/4 inches. Typical use cases include machine tool setups, conveyor components, and general mechanical assembly in light to heavy industrial environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF fine thread for precise engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eCup point geometry bites into shaft surface to prevent rotation and axial slip\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile and torsional strength\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex socket drive — accepts standard hex key or T-handle driver\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 3\/4 inches suits standard shaft collar and hub depths\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-20 UNF cup point set screw per ASME\/ANSI B18.3 and ASTM F912, suitable as a replacement or stock fastener in any mechanical assembly requiring a 1\/2-20 headless hex socket cup point screw in Grade 8 alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a 1\/4 inch hex key or T-handle driver. De-energize and lock out all rotating equipment before servicing shaft assemblies. Do not exceed the rated drive torque for the hex socket size, as over-driving can strip the socket or shear the fastener. Ensure mating threads are clean and free of burrs before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3\/4 inches\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 Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/4 inches (0.2500 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: 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: 101593PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720546812210,"sku":"101593PR","price":4566.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04ba97c4ebc73f04be4c7d01b0efda2c.jpg?v=1788565899","url":"https:\/\/voomisupply.com\/products\/value-collection-101593pr-set-screw-1-2-20-x-3-4-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
