Coach Screw (For Fixing Pipes)

£10.00 – £12.00Price range: £10.00 through £12.00 +VAT

Zinc plated coach screws in packs of 10.

Clear

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.

All FAQ
What is the difference between satin chrome and polished chrome rooflight openers?

What is the difference between satin chrome and polished chrome rooflight openers?

Satin chrome has a brushed, low-sheen finish suited to contemporary interiors, while polished chrome has a bright mirror finish. Both are available in the telescopic hand winder range at Tuscan Foundry. The choice typically depends on the existing ironmongery specification.

Is a cast iron hopper head suitable for use on a listed building?

Is a cast iron hopper head suitable for use on a listed building?

Yes. Cast iron rainwater goods are widely accepted by conservation officers and historic environment bodies as the appropriate material for listed buildings. Tuscan Foundry's hopper heads are manufactured in solid cast iron to BS 460 specification and are suitable for all listed building classes. A linseed oil paint finish is also available, which is particularly appropriate for conservation projects.

How do I get a price for a cast iron airbrick?

How do I get a price for a cast iron airbrick?

Prices are shown on each product page. For project quantities, bespoke specifications, or conservation-related queries, please call us on 0333 987 4452 or use the contact form on our website.

What is the advantage of a louvre-face airbrick over a square-grid pattern?

What is the advantage of a louvre-face airbrick over a square-grid pattern?

The louvre face provides directional airflow and offers some resistance to driven rain entering the subfloor void, making it a practical choice for exposed elevations or properties in areas with significant prevailing wind and rainfall. The square-grid (school board) pattern offers a larger open ventilation area but less weather protection.

Which rooflight opener is best for a skylight above a kitchen sink or worktop?

Which rooflight opener is best for a skylight above a kitchen sink or worktop?

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.

What finishes are available on cast iron airbricks?

What finishes are available on cast iron airbricks?

Our cast iron airbricks are available in a choice of finishes including primer and painted options. If you require a specific finish for a conservation project or to match existing ironwork, please call us on 0333 987 4452 to discuss.

What sizes and weights are available for the Ornamental Airbrick?

What sizes and weights are available for the Ornamental Airbrick?

The Ornamental Airbrick (OAB) is available in three sizes: 225mm × 75mm (2.8kg), 225mm × 150mm (4.1kg), and 225mm × 225mm (5.8kg). All sizes have a uniform depth of 75mm, making them consistent to install across a subfloor ventilation course.

Do your steel brackets have a protective coating?

Do your steel brackets have a protective coating?

Yes. All our mild steel brackets are supplied in either silver or black zinc plate. This coating protects the metal however, both will need painting prior to installation.

We have chosen to use zinc plating for two reasons; firstly that it is a more environmentally friendly than galvanising and secondly that it does not block up the threaded part of the rise and fall cups in the way that galvanising does.

What finishes are available on your cast iron hopper heads?

What finishes are available on your cast iron hopper heads?

Our cast iron hopper heads are available in a standard primed and black-painted finish, ready for on-site topcoats. Heritage colour finishes and factory-applied linseed oil paint are available on request. Linseed oil paint is a vapour-permeable, period-appropriate finish particularly well suited to listed buildings and conservation area properties.

Can the louvre airbrick be used to replace an existing cast iron ventilation grille?

Can the louvre airbrick be used to replace an existing cast iron ventilation grille?

Yes. The Louvre Airbrick is dimensioned to standard brick course openings and is suitable for direct replacement of worn, broken, or missing original cast iron louvre grilles. If you are unsure of the size required, measure the opening in the brickwork rather than the existing damaged grille.
