Marutex sheet to wood
Marutex sheet to wood screws for timber, glulam and flashings
Marutex sheet to wood screws for timber-side applications
Our Marutex sheet to wood range is designed for fastening sheet metal and related details to timber-based substrates where you want a stainless solution for exposed, professional installations. On this page, we keep the scope tight to timber and glulam applications, including standard roofing and cladding screws, a higher-load glulam option, fittings to timber and a flashing screw for sealed detail work.
The main choice is not only about screw length. You also need to match the fixing to the application type - whether you are fastening the main sheet, a heavier roof build-up, a smaller fitting or a flashing detail. For the most relevant background, our guides on corrosion classes, stainless steel and drilling capacity are the best supporting reads.
Choose the right Marutex sheet to wood screw
Roofing and cladding to timber
Choose our roofing and cladding to timber screws when you are fastening the main sheet to a timber substrate and want the core Marutex option for stainless exterior work. This is the right starting point for standard timber-based roofing and cladding, while the glulam option below is the better fit when the load situation is heavier.
See sizes and details for our roofing and cladding to timber screws on page 8 in the catalogue.
Roofing and cladding to glulam
Use our glulam screw when the timber-side application carries higher loads, such as uninsulated load-bearing roofing sheet fixed to timber or glulam. It is a more specific choice than the standard timber screws, so it belongs in projects where the substrate and load case clearly call for that step up.
See details for our roofing and cladding to glulam screw on page 8 in the catalogue.
Fittings to timber
Choose our fittings to timber screw when you are fastening sheet metal parts and smaller fittings into timber and want a neater, more discreet head than a main roofing screw. It is the better option when appearance and detail work matter more than broad-sheet fastening.
See details for our fittings to timber screw on page 8 in the catalogue.
Flashing screw
Use our flashing screw for timber-side detail work where lower tightening torque, reduced cracking risk and a sealed finish are important. It is a more detail-oriented choice than the fittings screw above, and it suits flashing applications where installation control matters as much as corrosion resistance.
See details for our flashing screw on page 8 in the catalogue.
Detailed Marutex sheet to wood data in our catalogue
The catalogue page below gives you the clearest view of the Marutex sheet to wood range in one place. It lets you compare the four timber-side subgroups on this page - standard roofing and cladding screws, the higher-load glulam option, fittings to timber and the flashing screw - together with dimensions, drill capacity, bit/socket and pack size.
This is where the compact range data sits behind the selection guidance above, so it is the quickest place to confirm which timber-side Marutex option matches the job.

If you are unsure whether your project calls for the standard timber screw, the glulam option, a fittings screw or the flashing screw, we can help you narrow it down quickly. We also help with corrosion choice, drilling suitability and practical installation questions before you place the order.
How do I choose between the standard roofing and cladding to timber screws and the glulam screw?
Choose the standard timber screws for normal roofing and cladding fastening into timber. Move to the glulam screw when the application is in timber at higher loads, such as uninsulated load-bearing roofing sheet fixed to timber or glulam. The real decision point is whether you are doing standard timber-side sheet fixing or a heavier structural timber application.
When is a fittings to timber screw better than a standard roofing or cladding screw?
Use the fittings to timber screw when you are fastening smaller sheet metal parts and fittings and want a more discreet head and a cleaner finished look. The standard roofing and cladding screws are the better choice for main-sheet fastening, while the fittings screw is the more precise option for detail connections.
When should I use the flashing screw on this page?
Use the flashing screw when the job is about flashing details rather than broad-sheet fastening. It is designed for lower tightening torque and reduced cracking risk, and its head design supports a sealed installation, so it is the better fit for more delicate detail work around timber-side build-ups.
What matters most when choosing length for a sheet to wood screw?
Start with the full build-up you are fastening through and the timber member behind it. The screw has to suit the sheet or fitting, any intermediate material and the timber or glulam substrate, so length should be chosen from the real assembly rather than from the outer sheet alone. When the build-up changes, the right screw choice can change with it.
Do sealing washers and tightening method matter on exterior timber applications?
Yes, they matter. For external mounting - or where there is a risk of condensation or flooding - sealing washer use is important, and the screw should be tightened correctly rather than over-tightened. In practice, that helps protect the sealing function and avoid problems caused by crushing the washer too hard.
Can Unite help us choose the right Marutex sheet to wood screw for our project?
Yes. This page is meant to help you separate standard timber roofing and cladding, glulam, fittings and flashing applications, but project details still matter. If you tell us what sheet or fitting you are fastening, the timber build-up and the exposure conditions, we can guide you to the most suitable Marutex option faster.
