Screws for Light Steel With a 19mm Bonded Washer (Pack of 100)
If you’re fixing your roofing sheets to light steel purlins, such as our Z and C purlins, these Cladco TEK screws offer a practical fixing option for achieving a firm connection with added sealing at the fixing point. Featuring a self‑drilling design and a bonded sealing washer, they’re suited to a wide range of light steel roofing applications.
About Our Roof Sheet Fixings & TEK Screws
Fixing roofing sheets into light steel requires a screw that can cut cleanly through the steel while maintaining protection at the fixing point. Our self‑drilling TEK screws are designed for attaching metal sheets to light steel purlins, including Cladco Z purlins and C purlins, helping to support consistent installation across your roof.
Each screw is manufactured with a 5/16″ hexagonal head and includes a 19mm bonded sealing washer, made up of a stainless‑steel washer with a bonded neoprene pad. This combination helps maintain a tight seal between the screw and the sheet, reducing the likelihood of water ingress over time. We also sell a TEK screw socket driver tool, which is available here.

- Suitable for fixing roofing sheets to light steel purlins
- Self‑drilling design for efficient installation

Available in a range of lengths from 25mm to 175mm, these self-drilling screws allow you to select the most suitable option for your specific roof build‑up. We recommend 25mm screws for box profile sheets, 57mm screws for tile form sheets, and 75mm screws for corrugated sheets. Please note: spat washers are required when using 75mm screws.
Choosing the correct fixings for the application is important, so we recommend checking our Help & Advice section, where we have FAQs and installation guides for all products, before purchasing. If you’d prefer to speak to a member of our team, please feel free to give us a call.

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.
