IZY blade nut sized

These flanged bolts do grip like hell.....sometimes the underside of the flange has serrations to help it grip even more.
I use a full hexagon impact socket and a battery impact wrench which shocks the things off big time.

Your best bet is to look on youtube for the cheapies reviews, In the past ive used one of the cheap wheel nut wrench to 12v lead to car lighter socket it was great cracking them off

I have an 18v Hitachi and it’s used a lot. It cost a bomb - somewhere around £350 I think - and quite frankly I’m a bit disappointed by its performance. It sure does speed things up though!

definitely full hex is the way to go, 12 point always rounds off the corners then gives up.

With an 3 foot extension on a 14 mm Hex ( thanks LTL) it broken free phew the person must who did this up be in the Olympics.

My impact wrench would not budge it !
Will now get a set of these Have a choice ?? any suggestions for general DIY

3725 has these Sizes: 10, 12, 13, 14, 15, 17, 19, 21, 22 and 24mm.
3376 comes in these Sizes: 10mm, 11mm, 13mm, 14mm, 17mm, 18mm, 19mm, 21mm, 22mm, 24mm.

I’d probably go for 3725......difficult choice but 11mm is rarely called for unless It’s a bleed nipple.
You’ll probably find the full hexagon more beneficial than the fact that they are impact sockets.
