Found in parking lot of car dealership that’s undergoing construction

Pulled these out of my 1968 Lotus. Definitely not original. They are both very nicely made, stainless, slightly magnetic. Can't find any grading info on what two radial lines could mean. The previous owner was an aircraft mechanic and the car is peppered with various aerospace and Mil Std hardware.
I'd like to know what to look for so I can order some more. Two radial lines.

Edit: Looking through the MIL-HDBK-131A Spec, item 115 the two lines indicate 80,000 PSI screws in the .250 - 1.000 " range. This particular screw is a MS35308

Washer is dimensionally identical to a MS14183C4. Inconel washers would be a hilarious choice... perhaps they were in service on an aero engine and due to be replaced and the previous owner brought them home for his hardware bin

Found these at the shop. There’s a bit of everything here—Grade 5, Grade 8, some zinc plated, and some heavy-duty rust. You can never have too many spares, right?

First photo shows the 1/4 inch diameter fastener that I'm needing info about. The others are for context; I suspect the construction company bought this shelving as kits.

Is this just a nail with a very thick head? Can I remove it to reinstall the support over a wall stud? Will I damage my drywall by removing it (I can mud over a nail hole)?

If I can't "safely" remove it, would I be able to find similar support braces elsewhere to put on the stud locations?

Found this absolute unit at the shop today. I've seen some big ones, but this one is a beauty.

There's something about these metal bins that just works .

Hi everyone,

I have been to all the specialty hardware stores in my area and nobody can source this type of nut for me. I'm turning to the fastener community to try to help me out before I abandon it and look for an alternative.

This nut is being used with a #8-32 3/8th long screw.

Any help is appreciated!

Sorting through all these fasteners today. Wish me luck!

Internal hex didn't form

I’m not sure what it’s called I’m not really a craft person, but this fastener is part of a furniture but i need to remove the top but it’s stuck and won’t get out. I hope this is the right subreddit

M6 threaded.

This part was in my canopy bed. It was embedded inside the wood to hold the horizontal bar that attaches to the columns of the bed.

Ive tried looking everywhere for this part but only place i can find is from companies in China but they want order quantity of min 1000.

20 TPI, Pitch 1.25 mm, 30.9 mm OD, non tapered. It's on the end of a bell from a Swedish made train horn that was probably made between the 50's and the 70's. Other bolts on the horn are UNF but one small screw I also can't identify.

I am trying to find what I can only think to call a "slotted socket head cap screw", but I havent found anything. They may have been a custom part. They also appear to be semi-shallow, but that doesnt matter.

Trying to find this specific hardware piece used in a bear deterrent electric fence system. It's a grey metal cylindrical knob that screws directly into wood trim. The electrified bungee wire simply hooks over it. Not looking for plastic electric fence insulators. What is this piece called and where can I buy it?

I have a set of bar stools that were included when we bought our home. One of them is missing a foot, which I’m looking to replace.

From what I gather, it’s just a screw with a rubber cap glued onto the end. This was the best picture I could do - sorry if it kinda sucks!

First, the screw is likely metric, as it was made in China (and likely just a cheap Amazon buy). From what I gather, it’s an M6 with a 15mm length. The threads, however, are throwing me and I can’t find anything matching. It looks like, for every 5mm, there are 4 threads. Is that mean this is M6-0.66x15?

Second, and maybe not the place for it, but anyone have any recommendations for rubber caps for screws? They don’t have to be perfect matches - you can’t buy just one screw and one rubber cap
anyway.

Thanks!

Used to get these where i worked from Europe. Since moved on and cant get them anymore its a pan head screw with anti vibration on the underside they work in sheet metal really well.

They work well with 1/8 pre drill and i have 2 sizes 6mm and 12mm in length
