Set screws are fully threaded fasteners with no head, designed to secure a component — such as a collar, gear, or pulley — against or onto a shaft by bearing directly on the shaft surface through the flat point tip. The flat point distributes clamping force over a small area without marring the shaft, making it well-suited for applications where shaft integrity must be preserved. Installation requires a 1\/8-inch hex key. This fastener conforms to ASME\/ANSI B18.3 and ASTM F912 standards.\u003c\/p\u003e\n\u003cp\u003eThis set screw is used across mechanical, industrial, and maintenance applications wherever rotational or axial position must be locked without a traditional bolt head. Common install scenarios include securing shaft collars on conveyor systems, locking pulleys on motor shafts, and fixing hubs in position during equipment assembly or repair. The flat point style is especially preferred when repeated adjustment or repositioning is expected, as it minimizes damage to the mating shaft surface over multiple tighten-and-release cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 alloy steel construction provides high tensile and proof load strength for demanding clamping applications\u003c\/li\u003e\n  \u003cli\u003eFlat point tip preserves shaft surface integrity during repeated adjustment cycles\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread for broad compatibility with standard inch-dimensioned tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch hex drive accepts standard hex keys and L-wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush or below the workpiece surface to eliminate protrusion hazards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any tapped 1\/4-20 UNC hole requiring a headless flat point set screw to ASME\/ANSI B18.3 and ASTM F912 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSet screws of this type are installed by machinists, maintenance technicians, and millwrights using a 1\/8-inch hex key or L-wrench. Ensure the mating tapped hole is clean and free of debris before threading in the fastener. De-energize and lock out any rotating equipment before installing or removing set screws on shafts. Avoid over-torquing, which can damage threads in softer hub materials.\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: 3\/4 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 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: 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\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: 151241PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692008964402,"sku":"151241PR","price":4611.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9362aa9a263e8072a23387d275b71501.jpg?v=1788291979","url":"https:\/\/voomisupply.com\/products\/value-collection-151241pr-set-screw-1-4-20-x-3-4-in-flat-point","provider":"Voomi Supply","version":"1.0","type":"link"}
