Smile sex bolt/mating screw for torroid fixing

I have a 250VA torroid to mount, and it came with an M6 nut & bolt.

Apart from looking ugly it I dont really have enough clearance at either the top or the bottom. I'm searching & searching and cant find anything suitable.

e.g. Sex bolts & Mating screws - Bolt Depot

these are all too small for me. does anyone know a site that has bigger sizes? (M6 x35mm would be about right) thx in advance

The female sex bolt should accept any male bolt, so just look for matching heads in the length you want.

You MUST avoid the shorted turn.

If a metal bolt touches the yop and bottom of the case, assuming it is a metal case, you will destroy the transformer.

If the transformer is that tightly fitted into a case then you must use somrthing that does not complete the "turn" inside the transformer. ie a Nylon bolt.

M6 nylon stud is pretty commonly available.

thanks for that. I might try a m6 nylon spacer with two bolts

This is without doubt the most fnarr-tastic thread I've seen on here yet.

Don't try looking up "sex bolts, mating screws, and tying it down" on google images...........................
