Designed for professional roofline installers and DIY enthusiasts, these Seac 40mm black plastic headed pins provide a secure, low-profile fixing method for PVC soffits. They are engineered from marine-grade stainless steel to prevent rust and unsightly surface staining, ensuring a clean, long-lasting aesthetic for exterior installations. While they offer exceptional durability, users should ensure they have the correct installation tools to avoid damaging the plastic caps during insertion.

Yes, because they are manufactured from marine-grade stainless steel, they offer superior resistance to salt corrosion compared to standard galvanized nails.
These are primarily designed for soffits. For fascia boards, check the weight requirements of your specific board, as fascia often requires heavier-duty fixings.
Each box contains 250 individual 40mm pins.
The plastic heads are designed for outdoor use and are resistant to UV degradation, though minor fading may occur over many years of intense sun exposure.
We also offer a 30mm variant (MPN: TT30BK) if a shorter pin length is required for your specific installation.
Ensure you are using a rubber or plastic-headed mallet rather than a hardened steel hammer to drive the pins.
Check that you are not hitting a knot in the wood; if necessary, pre-drill a very small pilot hole to guide the pin.
To ensure the best results, verify that the timber framing is dry and free of debris before installation. These pins are compatible with standard PVCu soffit systems. For maintenance, keep the boxes stored in a cool, dry place to prevent moisture ingress before use. During installation, ensure the pin is driven in straight to maintain the integrity of the plastic cap's weather seal. No specialized cleaning is required post-installation, as the stainless steel is inherently resistant to environmental elements.
