cheap nasty radiators bad air bleed screws

[pagray]

can anyone tell me where i can purchase some replacement air bleed screws these radiators are square pressed stell rads very cheap, with air bleed screw top left hand corner to rear facing wall. someone has used a pair of pliars on them and rounded them off. hence air trapped unable to bleed.
sizes are 128 x 60 96 x60 48 x 60
odd sizes also used 15mm so far then microbore ! with drain valve between valves so not much to play with. can anyone id the rads who makes em so i can contact them seems all uk air bleeds are 1/8 1/4 1/2 sizes cans even get a close fit !

The bleed screw positions are where Barlo's are.

Can't help you with the bleed screws pagray other than try local tip, but if rads are as naff as you say why bother, just change the rads. Good rads at B&Q (and others) these days start at £9.99.
