4 mm Precision Bit Driver and Bit Set with Case (97-Piece)

• Precise Tip Geometry – Our 4 mm bits are made with tight tolerances for a secure fit in small screws, reducing slip and wear—crucial for high-value, sensitive electronics • Corrosion Resistant – The bits are made from hardened steel and finished with a zinc phosphate conversion coating that provides lasting corrosion resistance without altering dimensions or flaking, unlike chrome finishes • Clear Markings – The tip size and Tekton "T" are clearly stamped onto every bit • Bit Rails Have Soft, Secure Hold – The flexible rails securely grip the bits so they can’t fall out, while also making it easy to remove any bit one-handed • Easy Identification – High-contrast size markings are printed on the top of the rail
