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.

Anyone know what the heck the Pozidriv/Round Hole combo is for?
psychopaths
Don't quote me, but if I remember correctly, that is the larger size where the center is more solid like an elliptical half oval that extends nearly to the tip and the fins of the cross are attached. I think it also has the four Pozi minor points at 45 degrees from the cross. It has more of a spline like structure rather than the four pointed cone of a typical Phillips. That tip won't fit any other Phillips cross. I have only used them a few times, but have had many driver sets that include them. These type are usually tossed in my misc tools drawers because accidentally grabbing them is annoying..
Anti-removal/tamper resistant. The angle of the slots make it really easy to tighten, a fucking bitch to remove.
Wonder what the usecase for "H-type" would be
Anti-tamper.
I've seen them used to screw together toilet stalls in public bathrooms. Stops bored crackheads disassembling them.
For vocalists, if the only tool they have is a tuning fork.
Anti tamper and devices not intended to be opened. Ive seen them on european power bricks and blocks

Tag yourself I'm cheese square
If you're talking about the piefed tags, we need an auto tagger of some sort. I do not use tags for anything outside of AI fine tuning and training. I do not know the scope of use, and creating a bunch of single occurrence tags is beyond useless like what archive dot org has devolved into. We must have a system like gelbooru/danbooru for tags selection and moderation if that is to be sustainable or useful over time... or I simply do not understand the use scope.

Now I want to see a 'how it's made'.
Anything in the bottom two rows (other than hex) and you are welcome to curse the ancestry of the person who decided to use that type of fastener.
Okay, now I'm really confused. I was going to comment that the six-lobe shape is known to me as star bits, and then I did a search to see if anyone else uses the name, but these sites say they're 5-point bits, but they're star-shaped, not pentagons. The star bits in my security bit set all have six points, and I've not come across a five-pointed star screw because I'd surely remember being pissed off about them not working. Where/when are five-pointed stars used?
6-lobe, star, and Torx are all names for the same somewhat common screw type. Torx is a trademarked brand name however.
Separately there's a 5-lobe screw called 'pentalobe' that's looks just like the 6-lobe but with, well..., 5 lobes. It was developed by Apple iirc, to keep people out of their products and make repair harder.
My previous house had security screens on the windows with screws that I could never find a driver for - it was a few years ago, but I think they were pentalobe with the security nub in the middle. I didn't look too hard though - it was a good excuse to not wash the windows.
The common hack makes it easier to remember: the common star, or brand name Torx, is the same as a hexagon. If you have a full set of both SAE and Metric star drivers, there is a star that will fit tightly into nearly all hexagon cap screws. If you strip a hexagon screw cap, using a star driver will often work to remove it. This only works because it is the same number of points.
There are many other types, but the common star is the 6 point.
Nice drawing, but how exactly is this a guide?
I would actually love to see explanation of what is best use case for the screws (the first two rows)
Try designing stuff to share with people in CAD. You'll quickly learn to collect such references.
You only need Torx screws (six-lobe) The only reason to have a bit set with the rest of the heads is so that you can remove an old fastener and replace it with torx.
Give me a bunch of flat phillips/slot and I'll assemble the world
