Bought a new box of screws, and the T25 bit is a different style than normal

Usually the boxes of screws come with the bottom, more silver bit. But today's box had the duller grey, bit with a green lap band. No idea if one is better than the other or not.

Edit: Thanks to @0x0@infosec.pub for the wiki article!

Bits like that are used for impact drivers

That reduced diameter acts as a spring to absorb some of the torque being transmitted from the impact driver to the fastener.

The straight bit will not flex or elastically deform, but will fail in torsion without warning. These bits are not "impact rated", but are meant to be used with hand tools.

TIL!

It's green because it's not quite ripe yet. Leave it in the sun for a few days, and it'll be good to go.

Seriously. Trying to chew that thing before it’s time and you’re gonna lose teeth.

Alternatively you can chew it when your time has come to speed things up.

Ooh, an upgrade! Yes, an impact-rated bit is better.

I had no idea that is what these type bits are. I bought a whole bunch of the dewalt clam shell cases full of bits from woot years ago, two of the cases are all this type bit. I am moving those into my impact driver bag.

Huh. I had no idea that one would use an impact driver on Torx screws.

I kind of mentally associate Torx with (delicate) personal electronics and associate impact drivers with big, heavy pieces of hardware with rusty bolts.

TranscendentalEmpire@lemmy.today · 6 pts · 115d

Torx is pretty standard for just about any kind of hardware nowadays. It's actually more appropriate for construction than delicate electronics as it allows a lot more torque with less slipping. One of the benefits of a Phillips or flathead is that you'll probably strip the screw before you over torque and break something.

I am using a cordless impact driver, which is like a cordless drill. Rather than what a lot of people imagine, an air driven impact wrench.

Vs

My impact driver accepts the same bits I would use in my cordless drill. I do have some attachments so I can use sockets and such in it for auto repairs. But I now have a cordless impact wrench I use for that more often.

Oh, I thought it was a spirit level mid bit. I was trying to figure out how the structural integrity would work.

About as well as a guide bit on Milwaukee s hole saw kits

I have only bought 1 and I still feel that.

are they color coding torx bit sizes now?

No, that one's just lime flavor

Good, cause sour apple sucks.

Darkassassin07@lemmy.ca · 6 pts · 115d

Some brands do; but they don't follow a standard, so the colours are different between sets :/

X@piefed.world · 3 pts · 115d

It’s got that glow in the dark upgrade, for when you need to fasten screws in stealth. Handy!

KingGordon@lemmy.world · 2 pts · 115d (1 reply)

If its been built recently, probably not better.

nocturne@slrpnk.net · 3 pts · 115d

That is where I was leaning too. It was the only bit I used today, and it performed well enough. I did strip one screw, but that was my fault, and it backed out just fine.
