It features a 1\/4-28 UNF thread with an overall length of 1-3\/4 inches, driven by a 1\/8-inch hex key. Manufactured from alloy steel, this set screw delivers the strength and hardness required for holding collars, hubs, pulleys, and similar components firmly against a shaft. It meets ASME\/ANSI B18.3 and ASTM F912 standards, confirming dimensional and material conformance for industrial and mechanical applications. The cup point bites into the mating surface to resist rotational and axial movement under load.\u003c\/p\u003e\n\u003cp\u003eThis set screw is suited for use in light-to-medium duty mechanical assemblies across HVAC equipment, motor drive components, fan hubs, and general industrial machinery. The 1\/4-28 UNF fine thread provides strong clamping force in tapped holes and is commonly found in precision shafts and machined housings. Sold in a minimum order quantity of 100 pieces, this fastener is appropriate for professional shops maintaining inventory for recurring service and repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into shaft material to resist axial and rotational movement\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF fine thread for high clamping force in precision tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch hex drive compatible with standard hex keys and ball-end drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for hardness and strength in demanding mechanical applications\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1-3\/4 inches for deeper thread engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fastener for mechanical assemblies requiring a 1\/4-28 UNF cup point set screw with a 1-3\/4-inch overall length and 1\/8-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or qualified HVAC and mechanical technicians using a 1\/8-inch hex key or ball-end driver. Always de-energize and lock out equipment before servicing any rotating assembly. Ensure the tapped hole is clean and free of debris before threading the set screw to prevent cross-threading or galling. Do not over-torque alloy steel set screws in soft-metal hubs, as the cup point can damage the shaft surface 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\u003eOverall Length\u003c\/strong\u003e: 1-3\/4 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 inch (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\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F912\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\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: 601237PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715683451186,"sku":"601237PR","price":6822.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/729a1cb63ee04b82f0244ac825c92f0c.jpg?v=1788517181","url":"https:\/\/voomisupply.com\/products\/value-collection-601237pr-set-screw-1-4-28-x-1-3-4-in-cup-point","provider":"Voomi Supply","version":"1.0","type":"link"}
