Wera 05066910001 T40 Torx Bit 5/16 Inch Drive

Product Description

The WERA 05066910001 is a T40 Torx screwdriver bit with a 5/16 inch hex drive shank and an overall length of 1-3/8 inches. It is designed for use with power tools, impact drivers, and bit-holder systems that accept the standard 5/16 inch hex drive interface. The T40 Torx profile provides a positive engagement with matching fastener heads, reducing cam-out under torque. This bit is appropriate for professional tradespeople working in HVAC, electrical, plumbing, and general mechanical service where T40 Torx fasteners are encountered in equipment assembly or disassembly.

This bit suits residential and light commercial service applications. It is commonly used when servicing equipment panels, motor assemblies, and enclosures that use T40 Torx fasteners. The 5/16 inch hex shank is compatible with standard bit holders and quick-change chucks found on cordless and pneumatic drivers used by HVAC technicians, electricians, and plumbers in the field or shop.

Installation Notes

This bit is installed by a qualified technician into a compatible 5/16 inch hex bit holder or quick-change chuck. Ensure the driver is powered off or the tool trigger is locked before inserting or removing the bit. Do not use this bit with a driver that exceeds the torque rating appropriate for the fastener being driven, as overloading can damage the bit or fastener head. Inspect the bit tip for wear before each use and replace if the Torx profile shows signs of rounding.
