Manufactured from Grade 8 alloy steel, this screw offers high tensile strength and resistance to deformation under load. It features a 1\/4-20 UNC thread with an overall length of 5\/16 inches and is driven by a 1\/8-inch hex key. Compliance with ASME\/ANSI B18.3 and ASTM F912 standards confirms dimensional accuracy and material performance. Machinists, millwrights, and maintenance technicians install these in production and repair environments.\u003c\/p\u003e\u003cp\u003eThis set screw is suited for use in rotating equipment, shaft collars, pulleys, couplings, and mechanical assemblies where the flat point distributes clamping force without gouging the mating component. It is appropriate for both light industrial and general mechanical applications. The 1\/4-20 UNC thread size is one of the most common thread designations in inch-standard mechanical assemblies, making this screw a versatile stock item for maintenance and repair operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFlat point design distributes load evenly without damaging shaft surfaces\u003c\/li\u003e\n\u003cli\u003eGrade 8 alloy steel construction for high tensile and yield strength\u003c\/li\u003e\n\u003cli\u003e1\/4-20 UNC thread for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n\u003cli\u003e1\/8-inch hex drive for use with standard hex keys and Allen wrenches\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F912 dimensional and material standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series set screw for use in any tapped 1\/4-20 UNC hole requiring a flat point fastener in industrial, mechanical, or maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 1\/8-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. Power down and de-energize any rotating equipment before accessing shaft collars or couplings. Clean threads and seating surfaces before installation to ensure full thread engagement. Follow applicable mechanical standards and facility safety procedures when working on rotating machinery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength (Overall)\u003c\/strong\u003e: 5\/16 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\/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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM F912\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: 151220PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718315737394,"sku":"151220PR","price":3380.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63b26d917060babdf1cbba5bf30b92b7.jpg?v=1788551966","url":"https:\/\/voomisupply.com\/products\/value-collection-151220pr-set-screw-1-4-20-x-5-16-in-flat-point","provider":"Voomi Supply","version":"1.0","type":"link"}
