Rules for Posting Guides on Our Community

1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

Community Guidelines

By following these rules, we can maintain a diverse and informative community. If you have any questions or concerns, feel free to reach out to the moderators. Thank you for contributing responsibly!

What is labelled "flat" here I've only ever heard of as "countersunk" and what's labelled as "slotted" I've only ever heard of as "flat head". Also wtf is "PF"?

I had the same thought! Also I’ve only ever heard “torx” instead of “six lobe” although I’m guessing torx is a brand name.

I thought, for some reason, that Robertson was ostracized from the screw world.

[–] HeyThisIsntTheYMCA@lemmy.world 1 points 5 hours ago

Yeah screw Robertson

Best drive going hands down. I don't need a deliberate tourqe out to save my driver, I'm a big boy. Plus it usually just breaks the screw

In the USA maybe.

Everywhere else it's pretty common.

Fun fact, Henry Ford wanted to use them on his cars, but tried to screw Robertson in the deal. His petulance is the reason that Americans can't benefit from this perfect design.

I knew there was some reason for it, but I couldn't get my brain to remember what it was; but this sounds familiar.

The one labelled phillips i only ever heard it being calles "cross" and the one labelled pozidriv i only heard it being called "star" but maybe is just my country

[–] TrickDacy@lemmy.world 2 points 14 hours ago* (last edited 13 hours ago)

Yeah, in the US I've only heard "Philips" or occasionally "four way". We say star here also though, but I think for the "six lobe" iirc

[–] mrgoosmoos@lemmy.ca 1 points 19 hours ago (1 children)

damn your area uses dumb names for things then lol

calling a drive type by the head shape, that's wild

[–] TrickDacy@lemmy.world 2 points 19 hours ago (1 children)

Thanks -- little known fact, I time traveled to a hundred years ago to invent these terms.
