40mm plastic headed nails are the go-to fixing for fascia boards, soffits, and uPVC or plastic cladding. The oversized plastic head sits flat against the surface and blends in with the material, leaving a clean, near-invisible finish rather than the obvious metal head you’d get from a standard nail or screw. Each box contains 100 nails, giving you enough to get through a decent run of fascia or soffit work without running short mid-job.
The 40mm length is well suited to fixing standard fascia and soffit boards where you need enough penetration to hold firmly without punching through or splitting thinner sections. The plastic head does more than just look tidy — it spreads the load slightly and reduces the risk of the nail pulling back through the board over time, which matters when the material is expanding and contracting with temperature changes through the year.
Where Plastic Headed Nails Fit Into Roofline Work
Roofers and cladding fitters have been using plastic headed nails for roofline work for years. They are particularly useful anywhere the finished appearance matters and exposed fixings would look out of place. Fascia boards along the eaves, soffit panels under the overhang, and plastic cladding on gable ends are all typical applications. The nails are available in black, brown, and white, which covers the three most common colours used in standard uPVC roofline products. Matching the nail head colour to the board colour means the fixings largely disappear once the job is done.
These 40mm plastic headed nails are suited to hand nailing or use with a suitable brad or pin nailer that can accommodate headed nails of this size. On longer runs, having a consistent fixing method keeps the spacing regular and the finish professional. Most fitters nail at around 400mm centres, though following the board manufacturer’s recommendation is always the sensible approach.
Colour Matching Makes the Difference
It sounds like a small detail, but turning up to a white fascia job with a box of brown nails is the kind of thing that gets remembered — and not fondly. Ordering the right colour before you start is far less painful than picking them out afterwards. Each colour is sold as a separate box of 100, so it is straightforward to order exactly what you need for the job in hand.
Pro Tip: When nailing plastic soffit panels, fix into the centre of the slot rather than the edge, giving the panel room to move with temperature changes and preventing buckling during hot weather.
Plastic headed nails at 40mm are used primarily by roofers and cladding installers working on domestic and light commercial roofline projects. They are used to fix uPVC fascia boards to timber sub-fascia, soffit panels to joists or noggins, and plastic cladding boards to battened wall frames. The coloured plastic head is specifically chosen to blend with the material being fixed, keeping the finished surface looking clean and professional without the need for caps or covers.

Key Specifications
Length: 40mm
Box quantity: 100 nails
Plastic oversized head
Suitable for hand nailing or pin nailer
Not suitable for: Not suitable for structural fixing or load-bearing applications. Not recommended for fixing timber-to-timber where a standard wire nail or screw would be the correct choice.
Mark your fixing positions along the fascia or soffit board before nailing, typically at around 400mm centres or as specified by the board manufacturer. Hold the nail square to the surface and drive it fully home so the plastic head sits flush without cracking. Do not over-drive the nail, as sinking the head into the board surface can weaken the fixing and cause the plastic to split.
Select the correct colour to match the fascia, soffit, or cladding being fixed
Mark fixing positions along the board at recommended centres, typically 400mm
Hold the nail perpendicular to the surface to ensure a straight, clean drive
Drive the nail until the plastic head sits flush with the board surface
Do not over-drive — the plastic head should be flush, not countersunk
Check the board is sitting correctly before nailing off fully along the run
Can these 40mm plastic headed nails be used with a nail gun?
They are primarily designed for hand nailing. If using a nail gun or pin nailer, check that your tool can handle individually loaded headed nails of this size, as most nail guns are designed for collated nails and may not be compatible.
Do the three colours cover standard uPVC roofline products?
Black, brown, and white are the three most common colours used in standard domestic uPVC fascia and soffit systems, so in most cases one of the three will match. If you are working with a non-standard colour, the nail heads can be touched up with a suitable exterior paint if needed.
These 40mm plastic headed nails consist of a steel shank with an oversized moulded plastic disc head. The plastic head is designed to sit flush against uPVC and plastic board surfaces without cracking or deforming under normal nailing conditions. Available in black, brown, and white, the head colour is moulded through the plastic rather than painted. Each box contains 100 nails.
