Why not use pronged T nuts into the underside of the shelf? They only
protrude about 2mm below the shelf and the majority of the tread is
within the shelf. You could rebate them in flush if needed. They stay
in place when the bolt is removed. Come in most common sizes - from
Toolstation, etc.

I can't get to the inside of the guillotine to insert/tighten bolts or
screws. (The guillotine is like a metal box with the knife down one
side and L-shaped flanges underneath which have the fixing holes.
Trouble is, the flanges both point INwards. Once the 'tine is on the
shelf, the L-flanges with the fixing holes are hidden. I can't get at
them.)

Ah. Sound like rivnuts to the guillotine flange and countersunk machine
screws from the underside, then.


Or just spire clips. They are as hard as hell, grip on a flange, don't
need fixing tools and can be removed later if required.

Yep, this is what I finally used, as I couldn't find any outlet that
could supply just 4 rivnuts or rubber rivnuts. I happened to see a
small packet of 4 spire nuts at Halfords (in the nuts and bolts
section) so I got those. The guillotine is now fixed firmly and the
new "pseduo-Ikea/Ivar" drawer underneath looks great. Thanks for all
the responses in this thread.
