Set screws are fully threaded fasteners with no head, used to secure a component — such as a pulley, gear, or collar — against a shaft by applying direct pressure at the point. The cup point configuration bites into the mating surface to resist rotation and axial movement. Drive is via a 1\/8 inch hex key. The 18-8 stainless steel construction provides corrosion resistance suitable for wet, outdoor, and chemically exposed environments. This fastener is appropriate for mechanical assemblies across HVAC, plumbing, electrical, and general industrial applications.\u003c\/p\u003e\n\u003cp\u003eCup point set screws in the 1\/4-20 UNC thread size are widely used in residential and light commercial mechanical systems. Typical applications include securing shaft collars on blower wheel assemblies, locking set positions on valve handles, and fixing knobs or cams on control linkages. The UNC thread standard ensures compatibility with standard inch-series tapped holes. Installers working on HVAC blower assemblies, pump couplings, or motor shaft components will encounter this fastener type regularly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread for use with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e1 inch overall length provides adequate engagement depth for medium-duty shaft locking\u003c\/li\u003e\n  \u003cli\u003eCup point geometry bites into shaft surface to resist rotation and axial load\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in wet and outdoor environments\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch hex drive accepts standard hex keys and T-handle drivers\u003c\/li\u003e\n  \u003cli\u003eHeadless profile sits flush or below surface for clearance-critical assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock fastener for any assembly using a 1\/4-20 UNC threaded set screw with cup point and 1\/8 inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 1\/8 inch hex key or hex bit driver. Before installing or replacing set screws in rotating assemblies, de-energize the equipment and verify the shaft is stationary. Apply thread-locking compound only if specified by the equipment manufacturer, as removal difficulty increases significantly. Do not overtighten — the cup point can deform soft shaft materials such as aluminum or brass if excessive torque is applied.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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 inch (overall)\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: 1\/8 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: 0.01 pounds\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: R40324143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720954151218,"sku":"R40324143","price":3963.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ddab83ce6acf198bc17358a71f764ae0.jpg?v=1788571406","url":"https:\/\/voomisupply.com\/products\/value-collection-r40324143-set-screw-1-4-20-x-1-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
