BAHCO 4020L-M-4

The BAHCO 4020L-M-4 is a small metric combination wrench for precision work where there is often very little space around the object. It has a 4 mm jaw opening and is only 70 mm long, making it easy to access in compact assemblies.

The open end is angled at 22.5° and features a slimmer head, making it easier to reach nuts and bolts in tight areas. The ring end has an internal hex profile and a 15° angled offset, providing a secure grip while allowing extra working clearance when space is limited.

The tool is made of high-alloy steel and has a micro-matte chrome-nickel finish. This provides the classic, smooth wrench surface well-known in professional tool use.

Typical applications

The wrench is designed for use in radio, telecommunications, electrical engineering, precision engineering, and carburetor work. It is precisely in these types of tasks that a small and slim wrench can make all the difference when components are tightly spaced and require secure, controlled tightening.
