I used them when building up the enclosures for the vfd drives for my mills and lathes....Makes attaching everything so much easier....and easier to dismount parts if the need arises.. :coffee:

What I've been referring to as Hank Bushes are indeed the same a Rivinuts - seem to work OK if you get the hole sizes correct !
Googling tells me real hank bushes are pressed in from the rear of the panel with a press, whereas mine are set rather like a pop rivet from the front.
Pete.:
I installed a great many hank bushes as an 'apprentice' sheet metalworker assembling light boxes for a big contract. Popped them in the hole and set them with a small ball pein hammer.
tom osselton:
I never heard of them before I had to look them up.
PekkaNF:
Pretty much all good ones needs accurate (reamed hole) and assembly with press to give any good service

But it is not diffct to asemble them right - if you have press and can make the anvil.
Muzzerboy:
Pekka - what you are describing is different to the Rivinut / rivnut / rivet nut everyone else is talking about. Your product is a solid insert that is NOT deformed itself during insertion, whereas the rivet nut is held in place by deformation of the insert by the tool.
In my multi-decade experience of these parts, the market leader (and originator) is PEM (Penn Engineering) https://www.pemnet.com/fastening-products/pem-self-clinching-fasteners-new/. In fact, if you look closely at the Captive Fastener online catalogue, you will see that the product design copyrights are actually owned by PEM.
