Zinc plated coach screws in packs of 10.
The coach screw is a heavy-duty zinc-plated wood screw used to fix cast iron downpipe strap brackets and holderbats to timber — typically to rafter feet, roof boarding, timber-framed walls, or wooden soffits where a standard masonry fixing is not available or appropriate. The coarse thread and hexagonal head of the coach screw provide high pull-out resistance in timber and allow the fixing to be driven and tightened with a spanner or socket wrench rather than a screwdriver.
Supplied in packs of 10. Zinc-plated for outdoor corrosion resistance. Appropriate for use with cast iron downpipe brackets on period buildings where timber construction is the available fixing substrate. For specification support, call 0333 987 4452.

A hit and miss vent has a sliding plate on the reverse of the grille that can be moved to open or close the ventilation apertures. This allows airflow to be regulated without removing or replacing the grille. The vent can be fully open, partially open, or fully closed depending on ventilation requirements.
Yes. A polished brass finish is historically appropriate for period buildings and is generally acceptable to conservation officers for listed building projects. If you are unsure about the specification requirements for your project, we are happy to advise — call 0333 987 4452.
Cast iron radiators cost no more to run than modern steel or aluminium radiators. Cast iron is a very efficient material at emitting heat, thus you have items like le creuset cast iron pans. Cast iron holds it’s heat extremly well, which means that the radiators stay warm for longer.
