The flat point distributes clamping force evenly against the mating surface without marring or deforming it, making it well suited for locking collars, hubs, and shafts in place. Driven by a 1\/8-inch hex key, the 1\/4-20 UNC thread engages quickly and holds reliably under load. Grade 8 alloy steel delivers high tensile strength in a compact form factor. This screw conforms to ASME\/ANSI B18.3 and ASTM F912 standards, confirming dimensional and mechanical compliance for critical fastening applications.\u003c\/p\u003e\n\u003cp\u003eThis set screw is used across a wide range of industrial, HVAC, electrical, and mechanical service applications where a headless fastener is required to lock rotating or sliding components without protruding above the surface. Typical install scenarios include shaft collars on fan assemblies, pulley hubs, and set-collar clamps on motors or blower shafts. The 1\/4-20 UNC thread size is one of the most common in light-to-medium duty mechanical hardware. Sold in a minimum order quantity of 100 pieces, this part is intended for shops, contractors, and service operations that stock fasteners in bulk.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlat point design distributes load without deforming the mating surface\u003c\/li\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread for broad compatibility with standard mechanical components\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch hex drive for use with standard hex keys and Allen wrenches\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 and ASTM F912 standards\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush or below the workpiece surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 UNC flat-point set screw suitable for use in any mechanical assembly requiring a headless fastener that conforms to ASME\/ANSI B18.3 and ASTM F912 dimensional standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSet screws of this type are installed by machinists, millwrights, HVAC technicians, and general maintenance trades using a 1\/8-inch hex key or Allen wrench. Always de-energize and lock out equipment before accessing rotating assemblies. Do not overtighten, as excessive torque on alloy steel set screws in softer mating materials can cause galling or thread damage. Verify thread engagement and seating before returning equipment to service.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5 inches (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Flat\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\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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 pieces\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: 151235PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696622174514,"sku":"151235PR","price":3832.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b517f822505659602d333fbc5e62d6e9.jpg?v=1788344555","url":"https:\/\/voomisupply.com\/products\/value-collection-151235pr-set-screw-1-4-20-x-1-2-in-flat-point","provider":"Voomi Supply","version":"1.0","type":"link"}
