Wera 05057470001 Screwdriver Insert Bit Set 17 Piece

Product Description

The WERA 05057470001 is a 17-piece screwdriver insert bit set designed for professionals who need reliable, multi-tip coverage in a single kit. The set includes Phillips, Torx, Pozidriv, and Slotted insert bits along with a 416 R T-Handle Bit Holder, making it suitable for HVAC panel work, electrical enclosure assembly, plumbing fixture installation, and general mechanical service. Hex sizes range from 3 inches through 8 inches, and Torx coverage runs from T-10 through T-40. The kit weighs 1.37 pounds, keeping it light enough for a tool bag or service van organizer.

This bit set is well-suited for licensed trade professionals working across residential and light commercial environments. Electricians securing panel covers, HVAC technicians fastening equipment enclosures, and plumbers assembling fixtures with varied fastener heads will find the tip variety practical on a single job. The included T-Handle Bit Holder improves torque control in confined spaces where a full screwdriver or impact driver cannot reach. The Pozidriv tips cover sizes 2 and 3, expanding compatibility beyond standard Phillips-only applications common on imported equipment and European-spec components.

Compatibility

Installation Notes

Insert bits should be seated fully into the bit holder or driver chuck before applying torque to avoid cam-out or bit damage. Confirm the correct tip type and size match the fastener head before driving to prevent fastener damage. Torx and Pozidriv tips are not interchangeable with Phillips heads even when sizing appears similar. Follow applicable NEC or equipment manufacturer guidelines when working inside energized or pressurized systems.
