Bit holder Wera 45 mm, compact magnetic bit extension for screwdriver bits

Wera bit holder 45 mm is a compact magnetic bit extension designed to hold and extend screwdriver bits for improved access in confined spaces. With a 45 mm overall length, it provides a short, rigid extension that makes manual fastening and working with adapters easier while keeping bits securely retained during use. The holder is compatible with common 1/4" hex screwdriver bits and is intended for both hand drivers and many power tool adapters where a short magnetic extension is required.

Advantages

The bit holder combines a compact 45 mm form factor with magnetic retention to keep bits stable during driving operations. Its short length reduces leverage and wobble compared with longer extensions, helping maintain control when working in narrow areas. The design allows quick bit insertion and removal and is suitable for repeatable fastening tasks. Built to meet workshop use, it offers reliable mechanical connection to standard 1/4" hex bits.

Suitable for

• Accessing screws in tight or shallow recesses
• General fastening and repair work with hand drivers
• Use with power tool adapters where a short extension is preferred
• Quick bit changes in assembly and maintenance tasks

Key specifications

• Overall length: 45 mm
• Drive connection: 1/4" hex interface for standard screwdriver bits
• Retention: magnetic bit holding mechanism
• Intended use: short compact extension for improved access and control

How to use

Insert a compatible 1/4" hex bit into the holder until the magnetic mechanism secures it. Attach the holder to a compatible driver or adapter by engaging the hex interface. Use the combined tool to drive or remove fasteners, maintaining steady pressure and alignment to avoid slipping. For bit removal, pull the bit out of the holder while supporting the holder to overcome magnetic retention.

Usage recommendations

Use the bit holder when working in confined spaces where a full-length bit or long extension would reduce control. Regularly inspect the holder and bits for wear, and replace worn bits to ensure reliable engagement. Avoid exposing the magnetic mechanism to strong impacts or corrosive environments to maintain retention performance.
