I don't have a Mac dealer. However I still follow their flyers just in case. I also follow this YouTuber.
This looks like a good design, I'm really tempted to get a set.

Thanks for posting that Tim. That is the biggest advancement in hex or allen fasteners that I have ever seen. I have to go to MAC and check them out.

Sounds alot like WERA and what they call Hex Plus allen wrenches and bits. Same idea - putting the turning stress at different points on the fasteners to reduce stripping.

Looks interesting for sure.
George, thanks for the link to the Wera's, certainly along the same concept but Wera did it in 97 :))

Ah, come on! These bits take all the “fun” out of dealing with rounded fasteners. The hours of enjoyment we get from trying to find, or fab a substitute bit that will finally grip that old cap screw - LOL

IIRC Facom did something similar to Wera back in the '90's too. Neither make/made much, if any, difference IME. These MACs look like they might actually work.

Heck, just slobber some valve lapping compound onto the bit your using and pound it in with a hammer. Will pop that sucker right out! :lol_hitting:
You're welcome, Phil. I first discovered those Hex Plus bits some years ago when I was looking for a better way to remove stuck bicycle allen bolts. But I couldn't get ahold of anyone on the phone to get some info and order them, and now my bike repair work is basically nothing.

We quite often smack allen bolts with a punch and hammer prior to trying to unloosen. Impact driver also
George, thanks for the reminder on the valve lapping compound. I had heard that before but never tried it

Well Phil - in the spirit of full disclosure - I haven't used it either. I found and bought a little tub of the stuff after hearing the advice, but have yet to actually used it. Maybe just the act of buying it has scared all my fasteners and they've come off without additional assistance! :93:

As someone who had to deal with socket head cap screws multiple times a day I would have liked the new MAC ones. We went through a lot of allen wrenches as we used to use cheater bars on them on the punch press tooling. Last thing you want is a punch, die or other component coming loose and causing an expensive crash. After running hot rolled steel the mill scale would fill the screw heads so you had to get that out before loosening anything. I should have saved some of those wrenches up to 3/8" that I twisted up into works of art.

I have 3/4 aluminum plugs in electrical fittings that are 3/8 allen drive. As you can imagine aluminum rounds out easily. I'm going to order 3/8 RBRT just to try.
