Wera 05057657001 PH3 Phillips Power Screwdriver Bit 1/4 Hex

Product Description

The WERA 05057657001 is a PH3 Phillips power screwdriver bit designed for use with power drivers and impact-rated tool systems. Built with a 1/4 inch hex shank, it seats securely in standard quick-change chucks used across HVAC, electrical, and general mechanical trades. The overall length is 2 inches (50 mm), and the bit ships as a single-piece unit. This bit is engineered for torque transfer in driven fastener applications where a No. 3 Phillips head is required, such as large panel screws, equipment housing fasteners, and structural assembly work.

This power screwdriver bit suits residential and commercial trade applications where high-speed or high-torque driving is common. Electricians, HVAC technicians, and mechanical contractors use PH3 bits when driving larger Phillips fasteners found in electrical enclosures, air handler cabinets, and equipment mounting hardware. The 1/4 inch hex drive makes it compatible with standard bit holders and quick-release chucks found on most cordless drivers and impact tools in daily field use.

Installation Notes

Installation is performed by qualified tradespeople using cordless drivers or impact tools equipped with a 1/4 inch quick-change chuck. Ensure the bit is fully seated in the chuck before driving to prevent cam-out or tip damage. Do not use this bit in a manual screwdriver handle under heavy torque, as it is rated for power tool use. Follow equipment manufacturer guidelines for recommended torque settings when driving into sensitive assemblies.
