PREMIUM QUALITY: All nut drivers, socket adapters, quick-release extension bit holders, and wing nut drivers are made of Cr-V steel, with longer service-life, and higher shock resistance. And screwdriver bits are made of S2 steel for strong hardness.
HIGH PERFORMANCE: The 1/4" hex shank allows the nut drivers, adapters, and bits can be used with a variety of quick-change chucks and drills. There is a premium magnet inside each nut driver to hold the drill bit firmly. The quick-release extensions can quickly install the bits.
