Wera 4 mm Ball End Hex Key

This Wera hex key features a 4 mm tip size with long and short arm lengths of 6 inches and 3 inches respectively. It is manufactured from HAWA material with a black oxide finish that provides corrosion resistance. The tool is non-magnetic and has two tips for versatility in fastening tasks.

Suited for metric hex fastening in maintenance

The ball end design aids access to fasteners at an angle where a straight drive cannot reach. It is not intended for applications requiring an insulated tool or a tether attachment point. Users needing a non-sparking wrench or a different tip size should select another product.

Questions about this item

Should I pick the 4 mm long-arm or short-arm version for deep-set bolts?

The long arm measures 6 in and the short arm 3 in; the longer reach is better for recessed fasteners.

What does the black-oxide finish actually do when the tool is in use?

It adds corrosion resistance and reduces glare without affecting the non-magnetic property of the HAWA material.
