Wera 05073640001 31-piece Screwdriver Insert Bit Set

Product Description

The WERA 05073640001 is a 31-piece screwdriver insert bit set designed for professional-grade fastening across multiple drive types. The set covers Phillips, Torx, Pozidriv, slotted, and hex (Hex-Plus) bit styles, making it a versatile solution for HVAC technicians, electricians, plumbers, and general trades who encounter varied fastener heads in the field. Weighing 0.81 pounds, the kit is compact enough for a tool bag or service van. The included 1/4-inch drive ratchet and socket adapter extend the system's reach without requiring additional tools, and the integrated bit holder keeps bits organized and accessible during service calls.

This bit set is suited for residential and light commercial service work where multiple fastener types appear in a single job - common in panel access, equipment assembly, control board replacement, and cabinetry. The Hex-Plus bit profile is engineered to reduce fastener rounding, which is valuable when breaking loose corroded or over-torqued hardware. The range of Torx sizes from T-10 to T-40 and hex sizes from 3 mm to 8 mm covers the majority of fasteners found in mechanical equipment enclosures and electrical devices.
