The TEKTON 37-Piece 1/4 in. Bit Driver and Bit Set is an essential screwdriver set with a complete range of Phillips， slotted， square， hex and star bits. The bits are made of S2 steel with a zinc-phosphate coating that resists corrosion and they're designed to be longer than standard bits to improve your access to recessed fasteners. The 3-sided shape of the driver handle engages the structure of your hand， allowing you to comfortably apply more turning force， even when your hand is greasy or tired. Flexible rails securely grip the bits so they can't fall out， while also making it easy to remove any bit 1-handed. The included portable zipper case stores everything neatly and compactly， ideal for keeping in a glove compartment， kitchen drawer or taking on-the-go.

3-sided geometry of the driver handle provides the leverage you need to generate high turning force by hand， while round sections at the front and back ends of the handle create an ideal shape for quickly spinning long fasteners

Overmolded grip is permanently bonded to the handle and won't degrade or become sticky over time

Bits are held onto the end of the driver by a magnet that's friction-fit within the receiver so that it can't fall out
