Old Chain lock how to use

Hoping this counts as a fastener,

Found these chain lock thingys in the garage and they might be perfect for something I’m trying to do IF I knew how they worked,

Do they simply hammer together and apart? They’re pretty stuck now so was thinking penetrating oil or a soak in something before hammering them apart, but after that do they just hammer together and remain strong enough to pull a fairly heavy weight? (Not a car or anything, just trying to remove a stubborn pulley with whatever I have on hand)

Fully rounded nut cover caps?

I’ve got an issue where the pop-top on my campervan is snagging on the bolt ends and M6 nyloc nuts behind my awning mounts.

All morning I’ve been searching for a smooth plastic nut cover/cap that looks like the drawing on the right, but all I’m finding are covers with a step/ridge around the perimeter like the one on the left. The one on the left might still work, but I was looking for something smooth enough to guarantee a snag free operation.

I’m hoping for a suggestion of where to find the kind I’m looking for, or maybe some better wording to use as n my searches since nothing I’ve tried seems to be getting joy.

Thanks

Can't figure out the specs of a set screw I need.

I'm having no luck finding the specs of a set screw I need. The one I have now is too short to use for what I want to do. It's 6mm long, about 3.75mm diameter, and from the socket end to the top of the third thread the count is 3 per 2mm. The screw I need should be 11mm long. I got these measurements following instructions online. I'm confused, and any help would be very welcome. The set screw is to secure a new flex shaft to a rotary tool The screw I have is originally made for a Foredom machine, and now I bought a replacement shaft compatible for a new flex shaft machine I bought. I need to attach it securely to the new flex shaft with the set screw. Can anyone use these measurements to tell me what set screw I should get?

Direction to loosen this nut

GOT IT TY ALL

Sorry I know this is probably a dumb question but my brain is not working after spending so long trying to loosen this nut and just want to double check to confirm I’m going the right direction

Do I turn the nut the red or the blue direction?

Help abou toolkit: how to remove small screws #6 32 or 3 to 3.5mm diameter flush broken from aluminum case

Hello everyone! Good day!

So... I did two f.ups on the same housing:

how to remove flush broken small metal screws from a aluminium case is the problem in question...

Is there a kit with that small of a screw diameter (around 3-3.5mm)? I saw some ali.e kits for some 7 eur without holder...but they look very very breakable and sensitive...

Is there like a lefty thread small diameter kit to do this kind of fix?

Really appreciate your knowledge

Best regards

How do you remove these bolts?

How do you remove these bolts? Impact drill and air gun just strip them.

Polaris Magnum 330

edit: previous owner jb welded them on, just to be a dick apparently. Everyone here is being such an asshole and acting like I have no idea what I'm doing. I've got the right size shit, I just didn't know they were jb welded in there.

Crib Repair

How do I get Pic 1 hardware back in crib so it look like Pic 2?

For reference, this is the lowering mechanism for our crib which uses hex-top screws that screw into Pic 1 hardware to hold mattress in place and raise and lower it.

Two of the hex screws stuck into the screw-in housings from Pic 1 and unscrewed both screw and housing from the crib during assembly (Pic 3 and 4) My husband was able to separate the 2 pieces again but we have no idea how to put the Pic 1 hardware back securely. Thoughts?

How do I screw a hollow square aluminum tube to another hollow square aluminum tube?

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

Drift car bumper. What would you use here?

Hi all. Just bought a drift car and am trying to do better than the previous owner’s “zip tie everything” method.

(And yes there are rusty bits like the fender and lots of torn fiberglass. Fenders will eventually be replaced and I’m learning to repair fiberglass/do paint)

Wondering what the masters at /r/fasteners would use for the following to attach the bumper in the following spots:

1.) Rusted out fender where the original hole to mount the bumper has rusted away from years of zip tie pressure/wear.

Would be lovely to have this quickly come off/reattach. I was thinking Dzus but there’s also that “Mac Lifters” brand that’s specifically made for bumpers in that location. I am fine drilling into the bumper of course, but would prefer something like Dzus or a quick release button and not those ugly rubber band things.

2.) Front bumper attachment points in the engine bay where the support metal has sagged (going to be using riv-sert here to reinforce).

These could just be traditional bumper push-in clips in some spots, but for the grille/bumper middle spot where they’re “stacked” is there anything else I should be doing there?

3.) Side skirts are especially blind. The p/o just used self tappers (ew). Here I was wondering about Dzus again, but unlike the front bumper there’s really like zero access to get behind the panel, so curious about what else I could use.

Thanks for the help! As a hardware store frequent flyer I’m happy to have found this sub.

Need Help Sourcing a Type of (Anti-Vibration?) Lock Washer

I have an old Harbor Freight oscillating multi-tool that has a worn out washer with raised quasi-radial ridges which function to grip the blade. The washer is worn smooth in some areas and nearly smooth in the others, so it is no longer grips the blade which loosens 100% in 10-30 seconds of usage. It's an old tool (20++ yrs old).

I am not a machinist but figured you guys would know of a piece of of the shelf hardware that would work for this.

Alternately, anyone with a good quick & dirty solution I might have in my shop hardware (washer sandwich of sorts, etc.) that would get me up and running ASAP?

Here's the dimensions of this washer (Note it should have serious serrations on one side to grip the blade):

OD = 1"

ID = 0.315" (5/16")

Thickness = 0.75"

Thanks a bunch for any ideas!

Cannot get screw out

I have a ‘79 collegiate 3 that I need to change the tires on. This tiny screw and nut combo will not come apart, the screw just spins. I’ve never encountered a screw that won’t come out from a nut. They do spin independently so as to say not frozen together. Please help.
