Having bought screws just the other day, I was exasperated at how I could not figure out how long the screw actually is between my thumb and finger cause they're in a sealed box.

But I knew exactly which material they have been plated/hardened with. ๐Ÿคท

So, I understand why you posted this.

And the info about the (pre) drilling is just ๐Ÿ˜™๐Ÿ‘Œ

Yes, no need to guess or to do test holes to see which drill size is correct

[-] toynbee@lemmy.world 3 points 4 months ago

While I'm certainly no handyman, I usually just hold the drill bit to the screw to find one slightly smaller, then just use that.

The internet has ruined me because I looked at the part code and snickered.

Except for the German translation, which was either made by an idiot or Google translate...

[-] RamblingPanda@lemmynsfw.com 0 points 4 months ago

Huh, that's pretty normal around here. But the German translation of "thread" is wrong. Literally unusable screw, light it on fire immediately.

In spanish it says it is a yellow single thread, no mention to screws

Sideways on the corner of the box, "tornillo multiusos"

[-] lolcatnip@reddthat.com 1 points 4 months ago

I love how evocative the word tornillo is. In my mind it translates as "little twisty thing".

Strange that it recommends a 5.5mm drill bit for a 6 - 8mm plugs. I don't even remember seeing masonry bits of that size and for all the plugs I have I've always used the same size drill bit.

I am a complete amateur, but the box fits my experience.
If you use same size drill as the plug, the whole will be too big, and the plug is not fitting tight and firm enough, so the screw will just rotate the plug in the whole.
Especially in old brittle cement and "mortar" you need to be careful not to use too big a drill.

"Mortar" as the cement like material used when building a brick wall. I hope I'm using the correct word.

This might be true for some cheap brands, but it's certainly not true for any of the tens of thousands of plugs I've installed over my career. The plug diameter indicates the hole size you need to drill - 6mm hole for a 6mm plug, 8mm hole for an 8mm plug, and so on. The instructions here simply cannot be correct, as 6mm and 8mm plugs require different-sized drill bits, yet the packaging only mentions a 5.5mm bit. The only exception I can think of is concrete screws that don't need a plug: 6mm is correct for concrete, but for more porous materials like cinder blocks, you use a 5.5mm bit.

Judging by the fact that people in this thread are finding translation errors in the text there I'm assuming that's what has happened with the measurements too.

Here's the instructions for 6x30mm Fischer DuoPower Plugs for example.

I only see length on that box???
Also the image shows th plug sticking out, and as (2)40 mm, with something else that is unclear to me as (2)35mm.
Personally by the quality shown, the illustrations are useless to me.

The plug is 6mm meant for 4-5 mm screws, there is no indication of drill sizes that I can se.
There is also a measure on the right of (2) 12.5 mm which is completely unclear what is for?

I don't see how the image supports your point?

[-] Opinionhaver@feddit.uk 1 points 4 months ago* (last edited 4 months ago)

Pretty cleary states the drill dimension right here

There is also a measure on the right of (2) 12.5 mm which is completely unclear what is for?

It means that the board you're attaching to needs to be atleast 12.5mm thick for the plug to work properly.

and as (2)40 mm, with something else that is unclear to me as (2)35mm.

The hole needs to be atleast 40mm deep and the screw must be long enough that when accounted for the thickness of the material you're attaching it needs to be atleast 35mm into the plug.

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.
