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.

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.

We are refurbishing our bathroom and wish to place a heated towel rail in the new bathroom. Our plumber has advised that the heated towel warmer would be connected to the heating system, this would mean when we turn the system off in the summer that the towel rail will not work. What can we do ?

What is the difference between the Antique Black, Polished Lacquered, and Polished Brass finishes?

What is the difference between the Antique Black, Polished Lacquered, and Polished Brass finishes?

The Antique Black finish is cast iron with a blackened surface — the most historically accurate finish for cast iron ironwork and the most appropriate for the majority of heritage applications. Polished Lacquered is cast iron with a bright polished surface sealed with clear lacquer, suited to interiors and sheltered locations where polished ironwork is the specification. Polished Brass is solid polished brass throughout — the correct choice where existing building fittings are in brass or where a warm metal tone is required.

What size cast iron hopper head do I need for my project?

What size cast iron hopper head do I need for my project?

The right size depends on the width of your gutter run and the volume of water you need to collect. The Strayton H42A is available in four widths: 305mm (12"), 355mm (14"), 457mm (18"), and 610mm (24"). As a general guide, wider hoppers suit larger roof areas and heavier rainfall zones. If you are unsure, our team can advise based on your gutter profile and catchment area — call 0333 987 4452.

What building types is the Iron Works Hit & Miss Vent in Antique Black suited to?

What building types is the Iron Works Hit & Miss Vent in Antique Black suited to?

The Antique Black finish suits Victorian, Edwardian, and inter-war buildings where ventilation ironwork was painted rather than polished — estate houses, terrace housing, civic buildings, and rural properties. It is also correct for listed buildings and conservation area properties requiring like-for-like replacement of original ornamental cast iron vents.

Is a brass rooflight opener suitable for a listed building or conservation area?

Is a brass rooflight opener suitable for a listed building or conservation area?
