An unofficial chapter of the popular Dull Men's Club.

https://dullmensclub.com/

1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.

2. Original, Fresh, Meaningful Content.

3. Avoid repetitive topics.

4. This is not a search engine or advice forum.
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions, identify objects or get advice. We accept very few questions, and they must be over topics much more difficult than what is easily discoverable with a search. Also see rule 1, “comment baiting”.

5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.

6. Not hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.

7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

8. All polls must have an "Africa, by Toto" option. Why? Because we hear the drums echoing tonight.

That's just a myth. From the 1935 patent US2046839A by Phillips Screws Co.:

As pointed out in said prior application, one of the principal objects of the invention is the provision of a recess in the head of a screw which is particularly adapted for firm engagement with a correspondingly shaped driving tool or screw driver, and in such a way that there will be no tendency of the driver to cam out of the recess when united in operative engagement with each other.

Another object of the present Invention is to provide a screw head with a tool-receiving recess' which may be produced by a simple punching operation and at the same time preserve all of the desirable virtues of the screw head and the recess therein, and which results in certain additional advantages, namely, the screw head is left stronger near the outer edge than heretofore possible; the recess firmly and adcurately receives the driver and causes the driver to centralize it self with respect to the screw head.

The head was designed to be cheap to manufacture by cold-forming the metal.
