At 1\/8 inch overall length, this headless fastener is driven by a 0.050-inch hex key and seats into a mating surface to lock shafts, collars, knobs, and similar components in position. The cup point geometry bites into the workpiece for positive retention without requiring a through-hole or external fastener head. Grade 18-8 stainless steel provides corrosion resistance suitable for general industrial, mechanical, and light marine environments. Sold individually with a minimum order quantity of 100 pieces per order.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for light-duty mechanical assemblies where a compact, low-profile fastener is required. Typical applications include shaft collars, pulleys, gears, encoder wheels, and panel knobs in HVAC controls, electrical enclosures, pumps, and similar trade equipment. The fine 4-40 thread pitch allows precise seating torque and is common in small-diameter precision assemblies. The 1\/8 inch length is appropriate for thin hubs and shallow engagement scenarios where a longer fastener would bottom out before seating properly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread for use in standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003eCup point geometry provides positive bite and secure retention against rotation and axial movement\u003c\/li\u003e\n  \u003cli\u003eGrade 18-8 stainless steel construction resists corrosion in wet and moderate chemical environments\u003c\/li\u003e\n  \u003cli\u003e0.050 inch hex key drive for installation in confined spaces\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch overall length suits thin-hub and shallow-engagement applications\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush or below the surface for clearance-critical assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series UNC set screw for any 4-40 tapped hole requiring a cup point headless fastener in stainless steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 0.050 inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. De-energize or lock out any rotating shaft or powered equipment before installing or removing set screws per applicable OSHA lockout\/tagout procedures. Do not over-torque small-diameter set screws, as the 4-40 thread size has a low cross-section and is susceptible to torsional failure. Inspect the tapped hole for cleanliness and thread integrity 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: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1\/8 inch (overall length)\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: 0.050 inch\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\u003eWeight\u003c\/strong\u003e: 0.001 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\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: R40344442\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691678400818,"sku":"R40344442","price":1336.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03159e935c4435e04cc30b26d644ef2c.jpg?v=1788288350","url":"https:\/\/voomisupply.com\/products\/value-collection-r40344442-set-screw-4-40-1-8-in-cup-point-18-8","provider":"Voomi Supply","version":"1.0","type":"link"}
