For holding, through grommets, reverb tank to steel chassis, so not the
usual small ones for DSP boards etc. You cannot reinsert, blind, as the
4 splay bits are permanently splayed out.
Find a metal plate with holes the size to push each rivet in, to close
back the 4 splays, then old soldering iron and hotmelt glue the 4 together.
Reinsert through grommets and chassis, then the closer rivet, with more
force than usual to break the hotmelt .




Hmmm, I've read that several times now and am none the wiser.

I have a picture of a reverb tank with rivets through grommets on a
steel chassis, but then it goes all wibbly wobbly.


I would be inclined to use 4 x 3mm or 4mm bolts and locknuts.





Gareth.

I've yet to come across blind bolts, other than for masonry use.
ie one sided application , or you have to take the amp apart to fix the
tank, using ordinary nuts and bolts
for a Marshall Valvestate 100V.
Incidently attrocious main board holding, vaguely held nylon standoffs
that allow everything to flap about. Now there one substantial bolt and
nut and spacer went in there to hold heatsink, loads of 7W resistors,
big caps etc, from bouncing around so much
