As space is limited to tighten screw. Experiment

Hello, friends.

Article about that every man should be aware of screwdrivers and screws I received a great response. Not expected. Thanks!

One reader has put forward the hypothesis of a surprise for me on purpose screwdriver with PZ profile:

Come on... - I thought - are manufacturer of screwdrivers and screws to think that the furniture manufacturers become easier to work in hard to reach places. Especially because in such cases there is a flexible Extension and angular heads on screwdriver. But the worm of doubt gnawed me. How to check? Of course, taste.

I took bits and screws with PH and PZ profiles. I began to try to twist their holding bat relative to metal screws at various angles. First impressions - PH screws in general are not suitable for these purposes. Slightly deviated, they crackle, but not cool. The PZ samorezah bit at an angle keeps much better. But the author of the commentary he wrote about 40 degrees - this is quite a lot. Once I went to a dance))) and it is necessary to check it out.

Just remember the case when furniture-mounted kitchen block me, lacking a single supporting leg mounting base. Screw even short screwdriver it did not happen. I had to take a corner at the tip screwdriver. We simulate a similar situation.

Sustained distance between the boards 10 cm. Work-out bit in the geometry collated screwdrivers inclination angles with a distance from the face of improvised layout. Put labels. It remains to take the screws and tighten them to try.

And here's the result. PH screw with half grief fails to turn at an angle of 20 degrees. In this layout, it is 24 mm from the edge of a potential "hard to reach places."

PZ screw confident twisted at an angle of 30 degrees. Milestone of 35 he will not succumb. But even 30 degrees - is 40 mm from the edge. Almost twice as much as the black screws.

The conclusion of this story alone. If cramped conditions do not allow to tighten the screw PH, it is necessary to try to screws with PZ profile. Had I known about this feature before, would be fastened to the leg of a kitchen unit simple screwdriver.

If you still do not know what attachment screws securely as not to overtighten the screw and fold the edge screwdriver why, look at the previous article. Would you like to see more of such materials, subscribe to a channel and, of course, put your finger up 👍.
