Wiha 76506 Power Screwdriver Bit PZ.1 Pack of 10

Product Description

The WIHA 76506 is a PZ.1 Pozidrive power screwdriver bit designed for use with power screwdrivers and impact-rated bit holders in professional trade applications. Built from Chrome Vanadium Molybdenum steel, this bit delivers the toughness and wear resistance required for repetitive fastening tasks. It has an overall length of 1-9/64 inches and features a 0.25-inch hex drive shank for standard quick-change chucks. The 76506 ships in a pack of 10, making it a practical choice for stocking service vans or tool stations where bit replacement is routine.

This bit is suited for electricians, HVAC technicians, plumbers, and general contractors who regularly drive Pozidrive fasteners. The PZ.1 point size is commonly found on smaller fasteners used in electrical enclosures, panel work, and light fixture assemblies. The power-rated design handles the torque demands of cordless drills and electric screwdrivers without early tip rounding or cam-out under normal operating loads.

Installation Notes

Installation should be performed by qualified tradespeople familiar with power fastening tools and appropriate fastener selection.

Follow applicable codes and manufacturer torque guidelines for the fastener application being performed.
