VIPER Collated Gun Nails – Galv+ (NO GAS)

Viper gun nails are collated first fix nails designed for use with gas-free nailers. The D-clipped head profile packs more nails per strip than a full round head, which means fewer reloads and faster work across the day. Diamond points drive cleanly through timber without splitting, and the galvanised coating meets Service Class 2 requirements under Eurocode 5, covering external applications where moisture content stays below 20 percent.

These Viper gun nails are available in a range of sizes from 51mm x 2.8mm up to 90mm x 3.1mm, with both smooth shank and annular ring shank options. The ring shank versions offer significantly higher pull-out resistance than a smooth shank nail, which matters on jobs where the fixing will be under load, such as decking boards, roof sheathing, or treated timber in exposed locations.

Where Viper Gun Nails Fit Into First Fix Work

These nails are built around the demands of first fix carpentry: stud work, floor decking, roof structure, timber frame panels, and general structural joinery. The Galv+ coating means they can handle service conditions where a plain steel nail would begin to corrode, without needing the heavier coating of a hot-dip galvanised nail for fully exposed outdoor use.

The Eurocode 5 compliance gives specifiers and site managers confidence that the fixings meet the structural standard required for timber connections, which is increasingly asked for on managed sites and larger residential builds. Worth keeping a copy of the spec sheet to hand if the question comes up during a building inspector visit.

Ring Shank vs Smooth Shank

Smooth shank nails drive fast and are suited to work where the timber will carry load in compression rather than pulling against the fixing. Ring shank nails grip harder into the timber fibres, making them the better choice wherever uplift or lateral movement is a concern. If in doubt, ring shank is the safer call for structural work.
