The image below shows the usual blind standoff that's commonly available: I want a similar blind standoff, but with the thread coming from the other direction, like in my 3D view below. Do they exist? Where can I get them?
Thanks! What's your opinion on using these on a watertight enclosure? I've managed to use the standoffs (the type in my pic above) effectively before.
You might want to look at this link. Post installation, the nut seals well. The nut can be installed before or after pdr coating. Only care should be taken to insert plugs to prevent powder ingress on to the threads. http://www.filrox.com.tw/e/p06-products.htm The above link refers to a Taiwanese manufacturer. I have dealt with them before and are quite prompt in their delivery. You may also try AVDEL. http://www.avdel-global.com/en/products/speed-fasteners.html. This one seems to be more appropriate for your application. http://www.kenlon.com.tw/
I would caution the tension a fastener may exert on this style of insert if it is pulling the hex through the sheet metal it will have a good retention. But if the fastener side is the same side as the install side then it may pull out easily. This may not be an issue for the application, but worth considering.
Good point. That's a good reason to go with the nut style that Erich linked to (http://selfclinchdirect.com/self-clinch-blind-nuts.html)
That requires access to the back side. There are also blind fasteners that can be inserted from the bolt side. Rivnut is the first to come to mind. Their catalog is here: http://www.rivet-nut.com/2011 RIVNUT CATALOG.pdf
