1/4 Inch Pozidriv PZ3 Screwdriver Bit 50 mm Long

This 3-pack from Teng Tools provides three Pozidriv PZ3 bits built around a 1/4 inch hex shank, each measuring 50 mm (approximately 2.0 in) in overall length. The true PZ3 profile seats cleanly into matching Pozidriv recesses, engaging both the main flutes and the smaller intermediate ribs that set the Pozi system apart 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 handles. No adapters are needed, so transitioning between tasks takes seconds rather than minutes.

At 50 mm long, each bit delivers roughly twice the reach of a standard 25 mm insert bit. That additional length proves especially valuable when driving fasteners seated deep in countersunk pockets, recessed mounting holes, or behind obstructions where a shorter bit cannot maintain full engagement with the fastener head.

The Pozidriv recess appears throughout European-manufactured hardware, decking screws, cabinetry fittings, and electrical components. Although it looks similar to a Phillips cross at first glance, the geometry differs enough that using the correct Pozi tip dramatically reduces cam-out and fastener damage. Keeping a supply of fresh PZ3 bits on hand ensures that tip wear never forces you to improvise with the wrong driver profile.

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