I heard about Wera Hex Plus wrenches on the Project Farm channel. Bought them for work, and can now remove bolts that are damaged. Very impressive! So, I bought more Wera tools. Pleasure to use.
The 5mm in that low profile set is perfect for the bolt that's hidden underneath the EGR valve on the 2ltr mk 4 diesel mondeo's , it's worth 20 quid in frustration alone
I have never seen such a useless demonstration, Hex Plus keys are designed to bite in to the head of a hex head which has been stripped by another hex key, which they do very well. They were not designed to bite into a hex head which has been stripped out purposely in a different way. Ball end drivers should be left in the tool box and only used when straight end hex keys wont fit in to the hex.
