Zinc plated coach screws in packs of 10.
UK delivery from £30. Fittings are despatched boxed. See delivery rates.
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.

Tuscan Foundry supplies screw-jack rooflight openers in polished brass, satin chrome, and polished chrome finishes. Options include telescopic hand-winder openers in 150mm, 250mm, and 300mm sizes, fixed screw-jack stays, and pole-operated handles for high-level rooflights. All are designed for timber-framed rooflights and skylights.
The H530 measures 330mm wide x 150mm deep x 350mm high, making it well suited to Georgian and Victorian terraces, where a compact, narrow footprint is needed.
Hopper heads are supplied in red oxide primer ready for on-site painting, or pre-finished in black. A full range of Heritage Colours in traditional linseed oil paint is also available on request — please contact us for the swatch chart.
BTU stand’s for British Thermal Units. This was the old (Imperial) measurement for heat in connection with plumbing. Although BTU’s is a term still commonly used within the heating and plumbing, the industry is now going over to KW’s Kilowatts.
Yes. Cast iron hopper heads are the historically correct choice for listed and period buildings, and a like-for-like cast iron replacement is generally accepted without objection by conservation officers. We manufacture to BS 460 for genuine heritage character and durability.
For rooflights directly above a worktop or sink, a telescopic screw-jack hand winder is the most practical choice. Available in polished brass, satin chrome, and polished chrome, these openers allow controlled ventilation from a fixed handle position without requiring a pole. The 150mm or 250mm size is typically appropriate for standard-height kitchen rooflights.
Our cast iron hopper heads are available with 65mm, 75mm and 100mm round outlets, 75mm, 100mm and 125mm square outlets, and 100x75mm, 125x100mm and 150x125mm rectangular outlets, to match the downpipe already on site or specified for the project.
Our cast iron airbricks are supplied in primed finish, ready for on-site painting. This allows them to be finished to match the existing ironwork or masonry colour of the building. Standard black gloss is the most common finish for conservation and heritage projects.

A corner hopper head collects rainwater from two gutters running at right angles and channels it into a single downpipe. They are typically required at internal roof valleys, on hipped roofs, and wherever two runs of gutter converge at a corner. The Regent H1A is designed specifically for this application and is sized to suit the most common gutter profiles.
