Set screws are fully threaded fasteners with no head, designed to secure a component — such as a pulley, collar, or gear — against or onto a shaft by applying compressive force at the point of contact. The cup point geometry bites into the mating surface to resist rotation and axial movement. This fastener uses a square drive and follows the Unified National Coarse (UNC) thread standard. It is a common choice in mechanical assemblies where a flush or recessed fastener is required.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for industrial, mechanical, and light fabrication applications where a 3\/8-16 UNC thread is specified. It is used in shaft collars, set collar assemblies, drive components, and mechanical linkages across a wide range of equipment. Installation is performed by machinists, millwrights, and maintenance technicians. Length is measured under the head per standard convention. The minimum order quantity for this part is 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into mating shaft surface to resist rotation and axial movement\u003c\/li\u003e\n  \u003cli\u003eSquare drive accepts a standard square key wrench for high torque installation in tight spaces\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eGrade 2 alloy steel construction for adequate strength in general mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003e4 inch length accommodates deep thread engagement or through-hole applications\u003c\/li\u003e\n  \u003cli\u003eFully threaded, headless design allows flush or below-surface installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any assembly with a 3\/8-16 UNC tapped hole requiring a headless cup point set screw with a 4 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a correctly sized square key wrench. De-energize and lockout all equipment before servicing any rotating assembly. Do not overtighten — excessive force can strip the drive recess or damage the mating shaft surface. Confirm thread engagement is clean and the hole is free of debris before driving the screw to final position.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4 inches (measured under head)\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: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\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  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 409081PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695448129842,"sku":"409081PR","price":1196.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be41a0dcc522461885fdc62e98b0af08.jpg?v=1788335134","url":"https:\/\/voomisupply.com\/products\/value-collection-409081pr-set-screw-3-8-16-x-4-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
