1/4 Inch Pozidriv PZ1 Screwdriver Bit 50 mm Long

This 3-pack from Teng Tools delivers three Pozidriv PZ1 bits built around a 1/4 inch hex shank, each measuring 50 mm (approximately 2.0 in) in overall length. The true PZ1 profile seats cleanly into Pozidriv recesses, engaging both the main flutes and the smaller intermediate ribs that distinguish the Pozidriv system from a standard cross-point design.

The 1/4 inch hex shank slides directly into quick-change chucks, bit holders, and hex collets on cordless drills, impact drivers, and manual screwdriver handles. No adapters are needed, so switching from one task to the next takes seconds rather than minutes.

At 50 mm long, these bits offer roughly twice the reach of a standard 25 mm insert bit. That additional length is especially useful when you need to drive fasteners seated deep in countersunk pockets, recessed mounting holes, or behind obstructions where a shorter bit cannot maintain full engagement with the screw head.

The Pozidriv recess is widely used in European-manufactured hardware, cabinetry screws, electrical fittings, and decking fasteners. Although it resembles a Phillips cross at first glance, the geometry is different enough that using the correct Pozi tip dramatically reduces cam-out and fastener damage. Keeping a ready supply of fresh PZ1 bits on hand ensures that tip wear never forces you to improvise with the wrong driver.

Each pack contains three bits of identical size, so you can stage one in your drill, one in a secondary driver, and keep one in reserve. When a working tip begins to show rounding, swap it out immediately to maintain clean engagement and consistent torque transfer throughout your project.
