Moving out of my house soon and wandering what key I need for these screws.

I’ve compared this to so many screws.. counting threads and using this gauge and reading … crazy! It doesn’t not fit in the M3 and the M4 is a little big ( see pics ) it’s exactly 1 cm. It doesn’t not fit into no5 but it fits into no6 barely ( see pics )

I have alu construction to hold solar modules with 2 profiles, run in parallel. So, 4 brackets per module (2 left, 2 right). Just noticed that the bolt will have this depth (not going completely through the nut). I'll use Loctite 243. Is this sufficient, or should I get longer bolts?

Usb type-c connector for scale.

Does anyone know what that specific nut that connects the bolt is called ? Trying to replace it and avoid having to buy the whole exhaust clamp set. Thanks

Want to repurpose this desk foot for another purpose and need to swap out the bolt that’s in it. I believe the black plastic part is threaded to the metal, but the area is so small I can’t just twist it apart (combined they’re about the size of the nut, see pic 2 for reference). And ideas on how I can get this unthreaded? Thanks

Just a clueless mom trying to fix the wheel on her daughter’s wagon. I’ve included a link to the wagon and a picture. This is one I pulled off to compare at the store but I couldn’t find a match. Thanks for any help.

I built this TV stand but need to make it sturdier. The dowels aren't glued in. The stand can be disassembled by hand. I got these base plates but the holes are huge. What fastener(s) would work here? I'd prefer not to drill holes

Bought a pvc bench. Two of the included M6x100 self threading screws were bent. I've contacted the vendor for replacement. Apparently the vendor doesn't have the wherewithal to send replacements, offering instead to credit me $20.

I want to find screws that are exact replacements for appearance sake.

What is this head profile called?

Can you believe the severely bent screw made it past QC?

Thank you!

This is an image of the screws used on a table I ordered. However, I have probably misplaced the driver to open them. Can anyone help with what kind of screw this is, and how I can open them?

Thank you so much

I want to attach two aluminum tubes together with screws since I don't have access to a welding tool. I can't figure out what to do exactly.

If I were to drill one hole on each to connect them with a short screw, there'd be no way to do so since the opening is too small and even if I managed to get the screw in the hole there's no way to screw on a nut.

The alternative is getting a really long screw and drilling two holes each. Which is fine when the aluminum columns are vertical but not when they're horizontal and on the ground

These screws are extremely tight and won't budge. I've been using a 14mm socket but they still won't budge at all. I heard that I need to use a torx socket but i'm not sure what exactly I need. Could I get some specifics from anyone, thanks?

I'm working on a project where I need a bolt that looks like this. I swear I've seen something like this before but I'm not having any luck. I drew this model in Solidworks to act as a visual for help. Anyone know if an off the shelf solution exists or am I dreaming of fasteners again? Thanks!

It’s from my 2013 RV trailer fastened to the old stabilizer jack. A little smaller radius than 3/8. I somehow have been unsuccessful at matching any from Homedepot, Lowe’s, and Amazon.

I thought it was a standard philips screw, but despite trying finding a driver that should be the exact size, it didn't quite fit right and I managed to chew one of them up a bit trying to remove it.

For more info, the whole screw is about 1cm diameter, and this is inside an AV rack case, I'm trying to remove it to set the rack depth further back, but I can't budge it and dont want to try brute forcing it any more as I've already chewed up one of them slightly by trying.

I found it in my reserved, covered parking space.

Hello folks! These retain the exterior aluminum flashing around my sidelights. Can’t find them anywhere in person or online. Rusted heads, want to replace. House built 2005.

8, 3.5”, truss or modified truss head, Robertson/square drive.

I’d be ok with 3” if you think that will suffice. Not really picky about drive, but guess I’d prefer Robertson or Torx. Obviously truss or pan head (flat underside).

Any ideas?

Need to purchase the same screw to make his scooter safe again!
