Wera 05057603001 Power Screwdriver Bit 3 Mm Hex

Product Description

The WERA 05057603001 is a power screwdriver bit designed for use with power tools and impact-rated screwdriving equipment. It features a hex drive with a 3 mm specialty point size and a 1-inch overall length, making it suitable for precision fastening tasks where a compact bit profile is required. The bit is non-magnetic. It is intended for installation in professional trade environments where consistent, repeatable fastening torque is needed across metal, wood, or composite materials.

This bit is suited for use by electricians, HVAC technicians, plumbers, and general contractors who rely on power screwdrivers or drill drivers for equipment assembly, panel work, and fixture installation. The 3 mm hex specialty point size fits fasteners commonly found in equipment enclosures, terminal blocks, and light-gauge assemblies. The 1-inch OAL makes it practical for use in tight spaces where a longer bit would be obstructed.

Key Features

• 3 mm specialty hex point size for precision fastener engagement
• 1-inch overall length suitable for confined installation areas
• Hex drive shank with 0.25-inch drive size for standard power tool chuck compatibility
• Non-magnetic construction
• Designed for use with power screwdrivers and drill drivers

Compatibility

Designed as an OEM-style replacement or direct-use bit for power screwdrivers and drill drivers accepting a 0.25-inch hex shank, compatible with 3 mm hex fastener heads.

Installation Notes

Insert the bit fully into the tool chuck before operating to ensure secure seating and prevent slippage during fastening. Power down all equipment before accessing fasteners on live electrical panels or energized assemblies. Use the correct point size to avoid fastener head damage, which can complicate removal during future servicing.
