The STEELMAN 41799 Precision Steel Shaft Screwdriver Set features versatile tools for working on electronics and appliances. The shafts are constructed of hardened carbon steel, ensuring they won’t round out with repeated use. Free rotating, swivel-heads allow you to apply even pressure while installing and removing small screws, and the knurled shafts prevent your fingers from slipping. Set includes 4 flat/slotted tip drivers sized 1.4mm, 2.0mm, 2.4mm, and 3.0mm and two Phillips tip drivers sized PH0 and PH1. The set also comes in a handy plastic storage case to keep all your tools together for when they're needed and the variety of tip sizes are ideal for working on eyeglasses, watches, laptops, desktops, mobile phones, and other small electronics.
