Was ist das für eine Schraube?
Hallo,
Weiß jemand was das genau für eine Schraube ist? Damit ist der Korb an meinem Fahrrad angebracht. Jemand sagte mir das es bestimmte Sicherheitsschrauben sind, ich habe auch ein Set bestellt mit Bits aber es hat leider keiner gepasst, sie waren dann entweder ein Millimeter zu klein oder zu groß.
The screw head actually seems to be outside the standard, probably to prevent theft. Apparently needs a special key to open.
I would ask the seller if he had such a key for you. You could open the screws. If he can’t help you, you can get similar screws with inbus head either with him or in the construction market and replace the screws.
I’ve already done that, so a piece of the bicycle basket is screwed. But he can’t help me anymore because it’s a bit older.
Screw a pattern screw out (e.g. with a Schrauenroter) and get inbus screws at the construction market or even better at the screw or iron goods store. Then exchange them all.
If you can’t release the screws, go to the bicycle dealer. He can help you. He might also have the spare screws with inbus head.
I also had to googlen:
This screw head drive meansY type(english, Chinese: Y TRI), alsoY形(Chinese, translated: Y-shaped),Tri-point(named by U.S. tool manufacturer) orTrigram. However, in North America and Europe it is often driven by the above-mentioned screw driveTri-Wingdesignated.

But they are not as rounded on the side as mine.
My answer has accidentally landed under the brook stilt, sorry.
Here again:
So exactly these screw heads are called Y-Type screw heads in the wiki. What round do you mean? The basic shape is the lens head. On the outside there is a flat ring, a flange. So you haveY-Type cutting head screws with flange.
I didn’t find those screws.
This is a typical “safety bit”, but with some caution it can be detached or tightened with a suitable flat screwdriver which fits slightly obliquely in 2 of the 3 recesses.
But a certain name doesn’t have it?

The screws with WD-40 also spray from the other side and then forcefully beat the bit in there to the need. You have a lot of bits you can try with, even those for the simple slot screws. You just have to exert proper pressure on the screw before you start turning.
So two are too small and two too big. It’s just a millimeter that’s missing.
? I just wrote four. Why don’t they fit? Are they too big or too small?
There are only 4 Y types in it or are there even more in the overview?
Yeah, they’re called 1,2,3 and four, real Y-bits. Are they all too big?
I already have the set: https://www.amazon.de/gp/aw/d/B0B93ZJ3NT?psc=1&ref=ppx_pop_mob_b_asin_image and there are also 4 and no one fits.
I trust to get those screws out with a normal screwdriver (and WD-40). However, it must have the right width. (Don’t worry, I have them all).
Yes, a set with the right Y-bits would of course be better. Here you can see what sizes there are:

Y0 or Y00, I’ll take you.
So could I order a set of many Y-type bits?
