Manufactured from alloy steel to ASTM F912 and ASME\/ANSI B18.3 standards, this fastener delivers reliable clamping force in high-stress applications. The 1\/4-28 UNF thread provides fine thread engagement, and the 7\/8-inch overall length suits moderate-depth installations. Drive interface is a 1\/8-inch hex key socket. This screw is installed by machinists, millwrights, and maintenance technicians working on rotating equipment, shaft collars, pulleys, and similar mechanical components.\u003c\/p\u003e\n\u003cp\u003eCup point set screws are used across a wide range of mechanical and industrial applications where a component must be locked to a shaft without a through-bolt. Typical installations include shaft collars, sprockets, gears, couplings, and motor components. The cup point geometry bites into the shaft surface to resist both rotational and axial movement. This part is sold individually but requires a minimum order quantity of 100 units, making it suitable for shop stock, maintenance departments, and production assembly operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into shaft material for positive rotational and axial resistance\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM F912 material grade requirements\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standard for socket set screws\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF fine thread for precise torque control and tight thread engagement\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch hex key drive fits standard L-keys and T-handle hex drivers\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch overall length suits a range of hub and collar depths\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 socket set screw suitable for any application requiring a 1\/4-28 UNF cup point fastener.

Ensure the mating shaft or surface is clean and free of debris before seating the cup point. De-energize and lock out any equipment before installing or removing set screws on rotating assemblies in accordance with applicable OSHA lockout\/tagout procedures. Do not over-drive the fastener, as the cup point can deform the shaft beyond the intended bite depth.\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 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7\/8 inches (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 (internal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\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: ASTM F912\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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\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: 601233PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722894082354,"sku":"601233PR","price":5279.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8394391968776040de975bce3c994e9b_36abdbb6-2191-4ab4-8fa6-f6ace9bf076b.jpg?v=1788597513","url":"https:\/\/voomisupply.com\/products\/value-collection-601233pr-set-screw-1-4-28-x-7-8-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
