Spring Head – Galvanised

Galvanised spring head nails are the go-to fixing for roofing felt, sarking felt, and similar sheet materials where a standard round wire nail just isn’t going to cut it. The wide, flat head spreads the load across the material surface, which means the felt stays put rather than tearing through under wind pressure or foot traffic. At 65 x 3.35mm, these are the most commonly specified size for standard roofing felt applications across the UK.

The galvanised coating is what keeps these nails serviceable long after the job is done. Out on a roof, a plain steel nail would rust through in a season or two, eventually staining the felt and losing its grip. Hot-dipped galvanising gives the nail a proper zinc coating that handles moisture, condensation and the kind of weather that reminds you why you got into roofing in the first place.

Where Galvanised Spring Head Nails Get Used

These nails are used by roofers, carpenters and general builders on a daily basis. They are the standard fixing for roofing underlays, breathable membranes, and timber sarking boards. You will also find them useful when fixing insulation boards to timber frames, securing vapour control layers, and attaching lightweight sheet materials where a screw would be overkill and a staple would not provide enough holding power.

The spring steel shank bites into softwood and OSB without splitting, and the head size means you are not pushing through the material with every hammer blow. It is a simple nail doing exactly what a nail should do, just with the right geometry for the job.

Available in pack weights from 0.5kg right through to 10kg, so whether you are patching a garage roof or fitting out a full new build, you can order exactly the quantity you need. Bulk weights save cost per nail significantly, and the TIMbag format keeps them easy to handle and pour on site without losing half of them to the gutters.
