It is designed for mechanical assemblies where a fastener must apply holding force against a shaft, hub, or mating surface without a protruding head. The cup point bites into the mating surface to resist rotational and axial movement. Fabricated from Grade 18-8 stainless steel, this fastener offers good corrosion resistance in moderate environments. Machinists, maintenance technicians, and millwrights commonly install these in collars, pulleys, sprockets, and similar power-transmission components.\u003c\/p\u003e\u003cp\u003eThis set screw is suited for use in both light industrial and mechanical maintenance applications. It is a standard UNC-threaded fastener compatible with through-threaded or tapped-hole assemblies where flush or below-surface seating is required. The square drive requires a square-key driver or wrench, which allows high torque application without cam-out, making it practical for installations that require firm seating of the cup point into a shaft.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCup point bites into mating shaft surface to resist rotation and axial movement\u003c\/li\u003e\n\u003cli\u003eSquare drive allows high-torque installation with reduced cam-out risk\u003c\/li\u003e\n\u003cli\u003eGrade 18-8 stainless steel construction provides corrosion resistance in moderate service environments\u003c\/li\u003e\n\u003cli\u003eStandard 1\/2-13 UNC thread for compatibility with common tapped assemblies\u003c\/li\u003e\n\u003cli\u003eHeadless design seats flush or below surface — no protrusion into surrounding clearance envelope\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC-threaded set screw for use in tapped holes requiring a 1\/2-13 thread, cup point contact, and square drive, typical in mechanical power-transmission assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or mechanical maintenance technicians using a properly sized square-key driver or Allen-style square-drive wrench. Ensure the tapped hole is clean and free of debris before threading the fastener. De-energize and lock out any rotating equipment before servicing shaft-mounted components that use set screws. Do not exceed the thread engagement depth of the tapped hole, as bottoming out under excessive torque can damage threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2 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: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Measurement Type\u003c\/strong\u003e: Length Under Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: R63006688\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718123127090,"sku":"R63006688","price":912.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ef88fd6c919ccdd58900ee55a9abfda.jpg?v=1788549979","url":"https:\/\/voomisupply.com\/products\/value-collection-r63006688-set-screw-1-2-13-x-2-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
