So they are 3BA square nuts then?.

[Clive HartlandParticipant @clivehartland94829]

Look like the nuts and bolts for erecting my Greenhouse.

about to say the same Clive. We used them on lightweight rooflight glazing bars, slid down the backs then bolted to the purlins.

Sounds like a pretty good greenhouse if its been make with solid wooden purlins, own build?

All the greenhouse fixings I have used were either M6 threads or 1/4" Whitworth, also usually made from aluminium.

If these are 3BA I would guess that they are specially made but its anyone's guess what they are for.

Michael, who said the purlins were wood?

[BazyleParticipant @bazyle]

3BA are often electrical fittings.
