Pressac boxes

sure they are not still BA threads?

anyway an M3.5 tap is always handy

If they're intended for use with BT Lineboxes then newer Lineboxes come with self-tapping screws. Older ones came with 3.5M electrical pattern screws and brass inserts to screw into.

Another example of petty cost-saving

snipped-for-privacy@gowanhill.com expressed precisely :

They were described as suitable for BT and LAN sockets, my LAN sockets arrived each with a pair of 3.5mm screws.

I have noticed some screws that seem to be hybrid screws and slef tapping having a kind of lead in sharp bit on the tip. Brian

Brian Gaff laid this down on his screen :

The seller of the Pressac boxes has assured me this is normal and that the faceplates are supplied with self tapping screws - mine were not. He says he has had some unwanted boxes delivered in error, which have proper tapped holes and is sending me some of these.

Thinking about it - I fitted a new BT master socket a while back, which included a built in broadband filter, that used self tappers for the plate.

"pressac boxes" presumably a make of back box that the faceplate mounts onto? The box would have to be PVC or metal for a self tapper to work. The hard, brittle, aldehyde boxes won't self tap and have brass inserts for 3.5 mm machine screws.

Tried fitting the screws without the faceplate getting in the way?

Dave Liquorice formulated the question :

They are a soft plastic and yes I tried them without the faceplates - no I still couldn't get a 3.5mm screw to start. The boxes I installed before I realised, I just used wood screws to fix the faceplates.
