extra-extra-extra long M3.5's? Need to find some!

[Rockingit]

Evening all,

just wondered if anyone knows where I can get some stupid-length (like 125mm+) M3.5's from. Someone decided to raise a floor by another 70mm odd but the boxes are set deep in the original depth screed. Prefer not to double-stack boxes if possible!

Think you can still get extension modules for socket boxes though you may need a few.

75mm bolts with m3.5 extender bolt onto the box

 

[mackers]

50mm screw and 2 extension studs?

 

[Guest112]

longest ive used are 70mm i think,,,youll have to get a few of the extension pieces all screwed in together lol

 

[telectrix]

get the silly buggers to raise the boxes.

I think i saw some in Selco today, didn't look that closely but i think they were about 125mm

Standard machine screws should be available off the shelf up to at least 100mm. For really long screws I've use extension nuts (sometimes called coupling nuts as well) and threaded rod in the past. When they're really long they become a pain to find the thread though.

Longest I have come across is 75MM. Could just use extension studs out from the back box though.

Go to your local machine shop( if you don't have a lathe) and get them to run you a length of threaded bar up and cut it to a length that will correspond to the adapter. better still do what Tel says.

Extension studs are like these, but have the 3.5MM thread on them to screw into the box. If needs be you can just keep adding and adding them together

Probably be easier if they had, you could just use screws and rawplugs then

you could always chuck in a gob of expanding foam and stick a dry-lining box in.

I know the things you mean, we use exactly the same thing in nylon for PCB mounts. I haven't seen them in steel but I'll keep an eye out for them, they're very handy.

No, they've managed a pretty good job of that one, too!! Shame really, as the plasters left LOADS of nice space to play with on the walls........

I think I'd use a few 35mm deep socket box extensions rather than extra extra long screws

 

[telectrix]

be plenty of room for the cables, anyway.

Most definitly, pretty sure that leaving that much gap between box and accessory wouldn't comply either. You'll probably have to extend the cable ends too, if already cut and made off!!

how many you looking for!

ive used ones at 100mm plus exsension studs in ahotel when they wanted the sockets to come through the bed post...... i wasnt there for first fix. they were awkward
