Choosing the correct size (in mm) for wrenches and Allen keys is crucial to ensure a proper fit on fasteners, which prevents rounding or stripping and enables efficient torque application. The best size depends on the specific hardware you'll be working with, so having a range of sizes allows for versatility across different tasks. Many products offer single sizes, like the Zebra Powerdriv Dual Ratchet Combination Wrench 11mm for precision jobs, while sets such as the Hexagon Socket Ball Head Extra Long Allen Key Set 9/Piece Wurth provide multiple options for various applications. With different sizes available, you can always find the right fit for your needs.
