Plastic Lumber Subframe Fixings – Hex Head Screws (50 Pack)
These 8mm hex-head screws, made from Ruspert®-coated steel, are perfect for recycled plastic joists. With a 6.3mm thread diameter for a strong, secure fix, choose 90mm for parallel joins or 125mm for noggins and corners. Supplied in boxes of 50.
With a 6.3mm diameter thread, Cladco plastic lumber subframe fixings feature an 8mm hex head and are designed for joining subframe components in recycled plastic and composite systems. They’re suited to building and tying together joists and rails in typical decking subframe layouts, balancing strength, ease of installation and value.
Use 90mm screws for smaller or parallel joins where materials sit side by side. Choose 125mm screws for noggins or perpendicular joins where extra reach is helpful. Both lengths are supplied in 50-pack boxes for simple handling on site and straightforward stock control.
Installation is familiar to most installers. Fit a suitable hex socket to a drill or impact driver and follow best practice on fixing frequency and spacing for your chosen subframe layout. The screws are fully threaded, providing consistent engagement along the fixing — a good match for plastic and composite subframe applications — without changing the standard installation approach.
These fixings are compatible with recycled plastic joists and posts and composite joists (structural and non-structural). For best results, store packs indoors in a dry environment and keep boxes sealed until use. Always plan your subframe layout first so you can estimate the quantity of fixings needed and avoid unnecessary returns.

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.
