Found it! Bally Backbox Hinge Screws (Elektra)

[Solar Sailer]

Any thoughts on the size or product code for the screws that connect into the T Nuts (4) into the cabinet.

I guess flat headed otherwise the backbox wont sit level?
Nothing in the manual.
TIA

I can try and get a photo of mine if it will help ?

Do you mean the bolts that hold the hinge onto the back box ?

Keyed carriage bolts, with nuts inside the box box

Sorry I was watching Flash Gordon! Photo attached. (I'll get washers for the bolt in situ)

Just a bolt. 95mm long. 15mm head. Not sure its original.
However Pinball Mania has backbox bolts here:

But suspect you want the others in the photo the ones at the bottom ?

Yep the screws that go in the two T nuts is what I'm after.

I will bring some bolt options over later for today's Greggs club

I thought the op was referring to the BB securing bolts, the hinge fastening bolts will be similar to this (from my Gold Ball). We can take the ones off fastening the hinge to the cab to measure them

Well after much distraction caused by the surprise addition of a tidy Time Machine in Mr Sailers line up we deduced that the required bolts appear to be 1/4" UNC 1" fully threaded
