It measures 3\/16 inches in overall length and is driven with a 1\/8 inch hex key. Cup point set screws are used to lock shafts, collars, pulleys, and similar components in place by biting into the mating surface. The 1\/4-28 thread designation indicates a 1\/4 inch nominal diameter with 28 threads per inch, conforming to the Unified National Fine standard. Installers in mechanical, HVAC, plumbing, and electrical trades reach for these when a flush or recessed fastener is required in a rotating or adjustable assembly.\u003c\/p\u003e\n\u003cp\u003eThis set screw suits applications where corrosion resistance is a priority, including wet environments, outdoor enclosures, pool equipment panels, and coastal installations. The 18-8 stainless steel construction resists rust and mild chemical exposure without the need for additional plating or coating. At 3\/16 inches in length, it is well suited for thin-walled hubs, small collars, and compact shaft assemblies where a longer fastener would bottom out or interfere with the shaft bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into the mating shaft to resist axial and rotational movement\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF thread provides finer thread engagement and better vibration resistance compared to UNC equivalents\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in wet and outdoor service environments\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch hex drive accepts standard hex keys and ball-end drivers\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush or below the surface for use in rotating assemblies and tight clearances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any assembly requiring a 1\/4-28 UNF threaded headless set screw with a cup point.

De-energize or lock out any rotating equipment before installing or adjusting set screws in accordance with applicable OSHA lockout\/tagout procedures. Do not exceed the rated torque capacity of the 18-8 stainless alloy, as stainless fasteners are more susceptible to galling than alloy steel equivalents; applying an anti-seize compound is advisable in applications subject to heat cycling or high clamping loads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength (Overall)\u003c\/strong\u003e: 3\/16 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/8 inches\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\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: R63266069\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691019501874,"sku":"R63266069","price":1379.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bcf30320ae229a690da0ddbcac73218.jpg?v=1788279349","url":"https:\/\/voomisupply.com\/products\/value-collection-r63266069-set-screw-1-4-28-x-3-16-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
