With a 4-40 UNC thread and a 1\/4-inch overall length, this flat-point set screw seats against a shaft or surface without concentrating stress at a single contact point. The hex drive accepts a 0.050-inch hex key for installation and removal. Manufactured to ASME\/ANSI B18.3 and ASTM F912 standards, this fastener delivers the dimensional consistency and tensile strength expected in precision mechanical assemblies. Suitable for use by machinists, maintenance technicians, and mechanical assemblers across industrial and commercial applications.\u003c\/p\u003e\u003cp\u003eThis set screw is used in applications where a component such as a collar, gear, pulley, or knob must be locked onto a shaft without a raised fastener head interfering with surrounding parts. The flat point distributes clamping force across the mating surface, making it appropriate for softer shaft materials or situations where shaft marking must be minimized. It is a standard choice in light-duty mechanical assemblies, instrument housings, and precision equipment where fine thread engagement and compact fastener size are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high tensile strength in a compact form factor\u003c\/li\u003e\n\u003cli\u003eFlat point design distributes load and reduces shaft damage compared to cup or cone point styles\u003c\/li\u003e\n\u003cli\u003e4-40 UNC thread provides fine-pitch engagement suitable for thin-walled or small-bore components\u003c\/li\u003e\n\u003cli\u003eHex drive sized at 0.050 inches accepts a standard hex key for controlled installation torque\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n\u003cli\u003eFractional inch measurement type with 1\/4-inch overall length for drop-in replacement use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC 4-40 set screw for use in any tapped hole or threaded insert conforming to 4-40 UNC thread specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or mechanical technician using a correctly sized 0.050-inch hex key to avoid rounding the drive socket. Ensure the mating threaded hole is clean and free of debris before installation. Apply thread-locking compound if vibration loosening is a concern in the application. Do not exceed the torque capacity appropriate for the 4-40 thread size and Grade 8 material rating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.25 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: 0.050 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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F912\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 151007PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703908598066,"sku":"151007PR","price":2823.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ea6c9d89eb4bedad0d0074113c82d551.jpg?v=1788419396","url":"https:\/\/voomisupply.com\/products\/value-collection-151007pr-set-screw-4-40-x-1-4-in-flat-point","provider":"Voomi Supply","version":"1.0","type":"link"}
