Wera 05345352001 Screwdriver Insert Bit T4 Torx 4 Mm

Product Description

The WERA 05345352001 is a precision screwdriver insert bit designed for T4 Torx fasteners with a 4 mm drive. At 1.75 inches overall length, this compact insert bit fits standard bit holders and power tool adapters. It is engineered for precision work where control and fit tolerance matter, making it a practical choice for HVAC technicians, electricians, and other trade professionals who regularly encounter Torx fastener heads on equipment covers, control boards, and enclosures. The short-form factor suits confined spaces and delicate assemblies where a full-length driver would be impractical.

This insert bit is suited for light-duty precision applications across residential and commercial service work. It is commonly used when removing or installing equipment panels, junction box covers, and electronic component housings secured with small Torx fasteners. At 0.025 pounds, it is lightweight enough for tool belt pouches or bit organizer cases without adding bulk to a standard kit.

Installation Notes

Insert bits should be fully seated in the bit holder before applying torque to prevent cam-out or tip damage. When servicing electrical or electronic equipment, de-energize and lock out the circuit before removing fasteners. Use appropriate hand tools or low-torque settings on power drivers when working with small T4 Torx screws to avoid stripping the fastener head.
