Wera 073391 Ball-End L-key Chrome-plated Metric Set, Retail Pack

The fit and finish on these are FAR superior to any L key set l have owned so much so that I tossed all of my other L keys, l did pick up the non ball end also for better control starting bolts

These keys have held up really well under months of daily use. The hex-plus can be the difference between drilling bolts out and using one of these wrenches to remove them. I've found on slightly damaged fasteners I can often get the hex-plus keys in when I can't get other hex keys to go in.
The chrome hasn't had any flaking/cracking/peeling issues. I've used these to break loose some very over-torqued bolts. I finally bent the 6mm a barely noticeable amount when we put a 2 ft breaker bar on it, and then put about 100 lbs of force on the end of that, the tip still looks like new. That was after bending 2 other wrenches (without using the breaker bar) trying to get that bolt out. The 2mm wrenches have also survived in situations where Bondhus and Eklind have failed miserably.

I highly recommend this set for the price, especially if they may be in a corrosion-prone environment where the black oxide finish doesn't do quite as well.

On of the most amazing tool you will ever have
