The WIHA 74636 is a power screwdriver bit designed for 40IP TorxPlus fasteners. Built from steel with a 0.25-inch drive size, this bit measures 2 inches in overall length and is packaged in a quantity of 10. It is intended for use with power screwdrivers and impact-rated power tools in professional trade applications including electrical, HVAC, and general mechanical assembly. The non-magnetic construction suits environments where magnetic interference must be avoided. Technicians reach for this bit when working with TorxPlus-head fasteners on equipment panels, enclosures, and assemblies.
This bit fits standard power tool chucks accepting a 0.25-inch drive insert. The 40IP TorxPlus profile engages security and high-torque fasteners commonly found in commercial HVAC equipment, electrical panels, and industrial assemblies. The 2-inch overall length provides clearance for most standard applications without requiring an extension. Supplied in a 10-count pack, it is suited for shop stock or service van inventory where replacement bits are regularly consumed.
Designed for use with power screwdrivers and insert-bit-compatible impact drivers accepting a 0.25-inch hex drive and 40IP TorxPlus fasteners.
Installation is performed by electricians, HVAC technicians, and mechanical trade professionals using power screwdrivers or impact drivers. Confirm the tool is powered off or the trigger is locked before inserting or changing bits. Match the 40IP TorxPlus profile to the fastener head precisely before applying torque to avoid fastener damage. Dispose of worn bits promptly, as a damaged tip can strip fasteners and create rework.
