Oddly enough, the familiar seller of these bolts was the first to express skepticism. It turned out that there are no secrets in miniature secrets: they are all twisted and unscrewed with the same keys included in the kit. It is enough to purchase two of the three sets available for sale - and you can go to work. The third set under the loud name “Anti-Voroff”, protected by a separate patent of the Russian Federation, stands apart: these screws can only be tightened with a special key, but never unscrewed. The manual suggests using a grinder if necessary. Wow!
But that’s what the laboratory of the ZR is for, in disbelief, to check. And we set the task to unscrew all the screws with improvised means. It turned out to be elementary! There would be a slotted screwdriver of suitable width at hand. One of the products surrendered to ordinary pliers.
What about proprietary screws? You really can’t grab them. It is necessary, as ordered, to cut the slot. The Bulgarian, however, does not wallow in the bushes, so the slot was cut for half a minute with an ordinary (not diamond!) Hacksaw blade. The screws were not even steel - aluminum! Although I liked the idea. Do not stint the developer on hardened steel, I would have to tear up the numbers with the root. By the way, the method “there is power - no mind” works anyway.
In our opinion, if you decide to complicate the life of the villain, just put a lock nut and do not tighten it tightly: let the screw scroll easily. And no secrets! Especially for the money.

The composition of the set of 4 bolts M6 × 1.0 × 12, wrench
Let the words about the wheels do not bother you. The size of the cogs leaves no doubt that the wheels have nothing to do with it. Making a suitable key is not easy - but why? Enough screwdrivers or pliers!

In this case, the pliers are not an assistant, but the screwdriver is very suitable. The promised Japanese steel may be applied, but to no avail.

The groove is complex in shape, but the screwdriver fixes clearly.

The original product can be ordered even with home installation. Pliers and screwdrivers will not help to cope with it. If the authors didn’t save on good steel, a hacksaw would not have done it either. Alas, a fly in the ointment spoils everything.
