Thanks for the reply, I have seen London screw but couldn’t see much in the way of wood screws from them, I will check the others to see if they are made in the UK.London screw, GWR, OSC amongst others for fasteners.
Armeg for SDS and there are plenty of companies supplying surgical instrument manufacturing with drills and reamers.
If you’re after specifically wood screws and drill bits you probably need to buy very old second hand ones, quality may be very poor.
what are you hoping to achieve from UK only parts?
Thanks for your concern, the companies you mentioned either only make machine screws/bolts etc or import everything else other than the carpenters mate range which seem uk made and looks interesting but only useful for external work, however I will order a sample pack to check them out.Sounds like you’re looking for complications that might not materialise. If you have current supply problems look for alternatives or carry more stock. Being UK based only I’d expect to make things worse for you as you will have a minuscule range of options
