Hi, I have some equipment mounted to an off-the-shelf aluminium plate (say 300 mm), and I have a flat 1m tall structure made of CFRP with thru holes and some titanium bolts, washers and locknuts. I'd like to design a bracket of some sort to attach the aluminium plate to the existing holes in the carbon fibre structure. The assembly will be occasionally outside in the dry (but perhaps humid), and 99% of its life will be indoors.
My concern is with all the dissimilar materials; whether we will see any galvanic corrosion over a few years, and so whether it need some passivation, coating or a complete re-think. It needs to be a rigid connection otherwise I'd like to put a rubber gasket between them and maybe add a bushing and try to electrically isolate the fasteners.
I changed the battery in my 2005 Mini Cooper S, and it went well enough. But I lost the bolt for my positive terminal cable clamp. Saved the nut and washer, but the bolt is just... gone. My current plan is to run by home depot and try to find a matching bolt. As far as I know, I shouldn't need anything special, just something to tighten the clamp onto the terminal, right?
Alternatively, I figured I could buy a replacement clamp and just use the whole nut-bolt-washer setup from THAT on my current clamp.
I'm 99% sure that will work, but I figure it would be a lot cheaper to buy the bolt at the hardware store. 2-5 bucks vs 20-30 bucks.
Looking to grab some really basic things like a pair of 1/4"x1" hex head bolts, home hardware is advertising up to a 10 day wait for curbside orders O_o. What have folks found to be the easiest/quickest place to pick up?
Hi, could someone please inform me as to what kind of fastener is securing my mono basin tap (see photos) and what the best way of removing it is?
thanks for any and all feedback just trying to figure out what makes a good wood fastener
Place I moved recently has a blind but it is only partial blocking not full and being on the ground floor it does not offer sufficient privacy especially when a car parks right outside my window and the headlights beam in!
I already have a tarpaulin from another place I lived I used for the same purpose I just need some way to hang it somehow utilizing the existing framework or adding something to it so I can hang it. It has eyes on each corner I just need something to hook them to on either side.
I thought S hooks but there is very little room to place them between the existing blind to hang them (I mean on the existing blind rail which I thought I might be able to hang them from).
I also don't want to take the existing blind down as they gave 0 storage space here and so it would be a big clutter if it was taken down.
Any other ideas? I thought I could tie something very fine like fishing wire to the rail on either side them put S hooks on the loop I make but wonder if anyone could think of a neater solution.
I'm working my way through the BOM and sourcing guide and stumbled over an inconsistency. In the sourcing guide the screws are either class 10.9 or 12.9 and the nuts 8.8 (which are intended to be used with screws class 8.8).
From what I understand when not used with a nut the screws will either go into the extrusions or threaded inserts in the plastic part. So does the class have any significance or could I get away with e.g. using 8.8 everywhere?
I see it a lot on cars where someone puts a breaker bar on a fastener and when it starts to break free it makes the very distinct pop/snap sound
What causes that and does it let you know anything if a fastener does that?
I also run into it when doing electrical with both old and brand new installs where the screw pop when you loosen them
Hi, I'm a new engineer designing parts of a device intended to be IPX4 rated. My questions is in regards to sealing the fasteners holding the enclosure together. Currently, they are inside where the gasket would be for the enclosure part faces, so isn't there the possibility for ingress from the fastener heads themselves? Any help would be appreciated.
I want a word that means "tight" or "fasten e" or an "ilo fastener"
