With a 1\/2-13 UNC thread and a 3\/4-inch overall length, this flat point set screw applies clamping force without a projecting tip, making it well suited for holding collars, hubs, and pulleys on shafts where flush or recessed seating is required. It is driven by a 1\/4-inch hex key and conforms to ASME\/ANSI B18.3 and ASTM F912 standards. Machinists, millwrights, and maintenance technicians working with rotating equipment and shaft assemblies are the primary installers of this fastener type.\u003c\/p\u003e\n\u003cp\u003eThis set screw is used across industrial, commercial, and OEM manufacturing applications wherever a concealed, torque-resistant fastener is needed. Typical use cases include locking sprockets, gears, couplings, and sheaves to shafts in conveyor systems, motor drives, and general mechanical equipment. The flat point minimizes surface damage to the mating shaft compared to cup or cone point alternatives, making it a common choice when shaft reuse or repositioning is anticipated.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction for high tensile strength and hardness\u003c\/li\u003e\n  \u003cli\u003eFlat point design reduces marring on mating shaft surfaces\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC coarse thread for reliable engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex drive compatible with standard hex keys and Allen wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 standards for dimensional and mechanical compliance\u003c\/li\u003e\n  \u003cli\u003eFully headless profile sits flush or below the surface of the mating component\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or stock fastener for any application requiring a 1\/2-13 UNC flat point set screw with a 1\/4-inch hex drive, conforming to ASME\/ANSI B18.3 and ASTM F912 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a correctly sized 1\/4-inch hex key or L-key wrench. Always de-energize and lock out rotating equipment before installing or adjusting set screws per applicable OSHA lockout\/tagout procedures. Ensure the tapped hole is clean and free of debris before threading in the fastener. Do not exceed the torque capacity of the fastener or mating material; consult applicable fastener torque tables for Grade 8 specifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3\/4 inches\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\/4 inches (0.2500 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\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: 151346PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717419860274,"sku":"151346PR","price":1310.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1d80457fd39fc88ca102fe428a2d9e2.jpg?v=1788540133","url":"https:\/\/voomisupply.com\/products\/value-collection-151346pr-set-screw-1-2-13-x-3-4-in-flat-point","provider":"Voomi Supply","version":"1.0","type":"link"}
