Screws to Wood With a 19mm Bonded Washer (Pack of 100)
When fixing roofing or cladding sheets to timber purlins, these TEK self‑drilling screws provide a secure, water‑tight solution. Featuring a 5/16″ hex head and a 19mm bonded sealing washer, they help deliver a reliable and professional finish. We recommend using 32mm screws for box profile sheets, while 45mm screws are better suited to tile form sheets.
About Our TEK Screws Screws to Wood
Cladco TEK type self‑drilling fix screws are designed specifically for fixing cladding and roofing sheets to timber purlins. Their self-drilling design allows for efficient installation while ensuring a secure and consistent fixing.
Each screw features a 5/16″ hexagonal head and a 19mm bonded sealing washer, incorporating a stainless‑steel washer with a bonded neoprene pad. This combination helps create a water‑tight seal at the fixing point, supporting a secure and weather‑resistant installation.
The type of TEK screw required will depend on the application and materials being fixed, so it’s important to select the most suitable option for your project. For further guidance, please consult our Help & Advice section or get in touch with our team via our Contact Us page.

Customer Collection Notice
Please ensure you have pre-booked your collection slot before travelling to site.
When arriving to collect your order, please report to a member of our Warehouse Team who will register your arrival and locate your goods. Once ready, your items will be picked and brought to your vehicle loading area.
During busy periods, there may be a short wait while our yard team assist other customers or complete other loading tasks. We always do our best to work within your booked collection time.
We respectfully draw your attention to the following important points:
- Loading is ultimately the customer’s responsibility. While our team can assist with mechanical loading using forklifts, we cannot handball items into enclosed vehicles. Customers must ensure their vehicle is suitable and that goods are safely loaded and adequately secured before leaving the premises.
- Sharp sheeting, metal goods, and long/heavy items may pose additional handling risks. Please come prepared with high-quality protective gloves, and any appropriate protection materials to avoid damage to your vehicle or restraints (e.g. ropes or straps). The edges of roofing sheets and metal products can be extremely sharp, and care should be taken when handling.
- We strongly recommend that customers bring their own straps, ropes, or other securing materials, as we are unable to provide these at the point of collection.
- If you are unsure of your vehicle’s load capacity, we can advise the approximate weight of your order in advance. It is your responsibility to ensure your vehicle is suitable for transporting the goods safely and legally.
- Cladco will not be held liable for any damage to your vehicle or goods once they have been loaded and leave our premises. Loading assistance is provided entirely at the customer’s own risk.
Click & Collect – Pre-Booking Required
You are welcome to collect your order from either our Okehampton (Devon) or Andover (Hampshire) site. All collections must be pre-booked in advance so your items can be picked, packed and ready for you.
Please do not travel to site without a confirmed collection time, as we cannot guarantee your order will be available.
Once your items are ready, you will receive an email with a link to book your collection slot. Please note, same-day collections are not available and bookings must be made at least two hours in advance.
When you arrive, please bring your order confirmation and follow the signage to the collection area where a member of our team will assist you.
