Tri Wing

[martin007]

I'm looking for a triwing bit.
Not to be confused with tripoint (Y) bits.

The tri-wing, also known as triangular slotted, is a screw with three slotted "wings" and a small triangular hole in the center. Unlike the "tri-point" fastener, the slots are offset, and do not intersect the center of the fastener. A version with left-hand threads is called an Opsit screw, where unscrewing can be done by turning the screwdriver clockwise, which is the opposite of tri-wing and regular screws.

The design was adopted by some parts of the aerospace industry, led by Lockheed in the early 1970s on the L-1011, but met with mixed results due to complaints of insert damage during installation.[citation needed] McDonnell Douglas also used this as a primary fastener on its commercial aircraft. British Aerospace and Airbus are also users of this fastener.

Preferably bits of 50 mm in length.
Items sold from ebay or aliexpress.

This German has them, but the collar is more expensive than the dog.

I have those. As part of my IFIXIT kit. I never had to use them though. I have used practically everything else in this box on laptops or phones or other things though. I recommend it.

I already own the vast majority of those screwdriver bits.
I have bought individually or small batches.


Now I'm looking for a TW bit.
If I can choose from 50mm.

[Burgerman]

I used to have al kinds of seperate bits or small cases of varying quality. In the end I decided to get these IFIXIT ones as everything is in one case. And they are great quality so no slipping, wearing or chewed up ends or breaking. And in the event you do manage to damage one they have lifetime warranty. Not that I needed it so far. But they are really tough. And I never found any phone or laptop or hobby things that defeated it! It has bits for everything.

You need all of these because you never know what job is next to fix! Like my dashboards speedometer a couple of weeks back To remove the damned air bag lamp!

I have a case of "spudgers" and other odball stuff you need on laptops and phones to strip and repair where screens or cases or trim need some force to take apart. All great stuff. Much cheaper than relying on "experts" to do anything for you. I used that set today to strip and modify my carers home defense gun. To fit a different barrel and lighten trigger.

Cant live without my IFIXIT stuff! Once you do it then you put all your other odd mixed bits in a bag in a draw as spares.

50MM?

Shorten them. Cut off 2 inches with a grinder. You have a thin grinding disk?

[martin007]

Yes, 50mm.
It's an excellent measure.

I have a disc, but I don't want to cut anything.
One of the reasons is that I don't want to spoil the bit.

I'm looking for something of medium high quality.
The problem is that the shipping is more expensive than the bit.

[martin007]

I don't need the bit urgently, but...

[Burgerman]

Tri wing...

[martin007]

That one doesn't fit in my toolbox.

[LROBBINS]

monoplane, biplane, triplane

[Burgerman]

Actually a monoplane has 2 wings..
This really has one!

I have found some triwing screwdrivers.
"Pro'sKit" manufactured.
Models
SD-081-TRI000
SD-081-TRI00
SD-081-TRI0
SD-081-TRI1

How to find out the size of the screw?

[Burgerman]

Well I would just buy a set. Then whatever you find in the future will fit. Hence the iFixit kit I llinked to before. Then it fits everything you will come across.

[martin007]

The 4 screwdrivers with the shipment come out for 17€
I prefer only bits...
...but quality bits.

I can't find any triwing quality bits.

[Burgerman]

Euros? Thats like not real money is it? Like monopoly.

Yes, thats why it just makes more sense to buy that big iFixit set that I have. All types, all sizes, everything you will ever need in one set. With lifetime replacement garantee. No more messing about and you can fix anything! And quality tools. Includes tri bits...

[martin007]

It´is a Spanish store.
In Spain the shops don´t accept pounds sterling.

[Burgerman]

Yes. They used to accept the real currency of pesatas. Now the fake made up "EU currency.

You cannot have a common currency (the fake one) across a widely varying bunch of 26 countries. Because the richer and more developed productive ones (like germany) then have a huge advantage as their currency is held at a too low level. Meaning they sell shit loads of stuff to the rest of the world/EU because their products and services are artificielly cheap.

The opposite happens to the less rich, less well developed countries. They are forced to have an artificially high currency value compared to what they need in order to sell produce and goods. Making them sell less and get poorer and poorer.

To increase exports you bank used to be able to reduce the currency value. Or increase it. Now you have no control. Which is why I see the Euro as a fake currency. The EU isnt a country. Yet it thinks it is! It has a flag. And an anthem. And its unelected leaders tell you all what to do taking the control away from your elected leaders of your country.

And what alternative do you suggest?
Should we print more peseta banknotes?
Are they being printed faster than the euro?
In a couple of years we would be Argentina or Venezuela.


P.S. The bulls look great from the barrier.

If you keep your socialist government and stay in the socialist EU your country and the rest of the EU will end up exactly like venuzuala. But with way more immigrants and crime from the mainly muslim 3rd world, and even more woke ideology and no free speech unless its the lefts free speech...

Yet this appears to be the way the whole EU project is intended to go. Already the unelected EU tell you what to do and fine you if you dont obey

You need a centre right free market government. A national border and the strength to deport all the 3rd world problems back where they came from and you need a war on "woke" and lefty ideology as well as low taxation, less handouts to the lazy, smaller government and a national currency. You would then have a country that was worth living in that would climb economically above all of the EU.

You have described the Franco period.
But Franco was not calling for elections.
People want to put the little paper of paper in the ballot box...
Democracy does not work in Spain.

[Burgerman]

It does. But you only get what the people VOTE for. If they vote for a dictator or socialist then thats what you get.

In venuzuala, the place with more natural oil reserves than anywhere on the planet they voted socialist. That took around 15 to 20 years to bankrupt the country. Now they are poor. So they think they need more government hand out to survive. So KEEP ON voting socialist. And thats why their economy failed and continued to do so.

Same happened for a century across much of the planet. Ended up with people in a massive poverty trap and the starvation on around 100 million with no way out. Socialism appears nice when exlained. Its actually very evil.
