The Tekton 134-Piece 4 mm and 1/4 Inch Multi-Bit Driver Set includes a 97-piece 4 mm bit set and a 37-piece 1/4 inch bit set. The 4 mm bits are ideal for repairing mobile devices, laptops, video game consoles, controllers, wristwatches, and a wide range of other small electronics. The bits are made with tight tolerances for a secure fit in small screws, reducing slip and wear—crucial for high-value, sensitive electronics. All of the bits are finished with a zinc-phosphate coating that resists corrosion. The included rails securely grip the bits so they can't fall out, while also making it easy to remove any bit one-handed. The rails can also stand upright on a flat surface, making it easier to see. High-contrast size markings are printed on the top of each rail. This set includes an aluminum 4 mm bit driver and a high-torque 1/4 inch bit driver. Each set of bits also comes in its own compact carrying case with contoured EVA foam and zippered closure. The firm but flexible cases are made out of a durable 3-layered material and won't break when dropped.
