Tired of screws falling off your driver? This 10-piece set from Uxcell has you covered! These are slotted (flat head) screwdriver bits with a super handy feature: they're magnetic. That little bit of grip makes a huge difference when starting a screw in a tricky spot. The tip size is 3mm (about 0.12 inches), which is a common size for many slotted screws. The shank is a standard 6mm (1/4 inch) hex, so they'll fit in any magnetic bit holder, drill chuck, or impact driver. They're made from tough S6 alloy steel. The set includes 10 identical bits, each about 2 inches long and gray in color. They're brand new, weigh about 88 grams total, and are perfect for your toolbox, workbench, or to keep in a portable kit. A simple, super useful upgrade for any DIYer or pro.
