Firmahold Hot Dipped Galvanised Premium Collated Gun Nails are a nail and gas pack built for structural framing work where corrosion protection is a requirement, not an afterthought. The hot dipped galvanised coating provides rust protection that meets building regulations and complies with Service Class 3, making these nails suitable for exposed and outdoor applications where moisture contact is likely. Available in four sizes from 51mm x 2.8mm up to 90mm x 3.1mm, each pack includes the gas canister alongside either 2200 or 3300 nails depending on the size chosen.
The 34 degree clipped head paper collation is compatible with all clipped head framing nailers. Firmahold have tested these across the board, so you are not tied to a specific tool brand. The clipped head design increases the number of nails per strip, which means fewer reloads and more time actually driving nails. The paper collation burns cleanly on firing and is a key reason these nails generate far fewer jams than plastic alternatives. Over 7.5 million shots without a collation issue is a figure worth paying attention to.
Why Hot Dipped Galvanised Nails Belong in Structural Work
Ring shank nails grip timber significantly better than smooth shank alternatives, which matters in structural applications where withdrawal resistance is part of the design specification. The diamond point aids penetration and reduces splitting, particularly useful when working close to timber edges or end grain. These nails conform to Eurocode 5, which covers the structural use of timber, so they are appropriate where engineer-specified fixings are required.
The high quality wax applied to the collation strip keeps feeding smooth throughout the strip and helps protect the nails in storage. If you are working on timber frame builds, roof structures, floor cassettes, or any structural timber application with an external or semi-exposed element, these nails cover it. The galvanised coating and Service Class 3 compliance mean they are not just adequate for the job but specifically rated for it.
Pro Tip: When working in cold conditions, keep your gas cartridge warm inside your jacket between uses as cold gas delivers inconsistent drive depth and can cause misfires that look like nail jams.
Firmahold Hot Dipped Galvanised Collated Nails are used in structural timber framing, roof truss assembly, floor cassette construction, stud walling, and timber frame build systems. The galvanised finish and Service Class 3 rating make them appropriate for outdoor structures, fencing, decking subframes, cladding battens, and any application where the nail may be exposed to moisture or humidity over time. Suited to groundworkers, structural carpenters, timber frame erectors, and site joiners.

Not suitable for: Not suitable for use in coil nailers or straight magazine nailers. These are clipped head collated nails at 34 degrees and will not feed correctly in tools designed for other angles or full round head nails.
Load the nail strip into your clipped head framing nailer following the tool manufacturer's guidance, ensuring the collation feeds smoothly into the magazine channel. Insert the Firmahold gas canister into the tool's gas chamber until it clicks securely. Set drive depth on the nailer to suit the timber density and nail size being used, then test fire into a scrap piece before starting the job.
Position the tool nose flush against the timber and fire. The paper collation burns on discharge and does not require clearing between shots. Reload when the magazine runs low rather than waiting for the last nail, as dry firing can cause feed issues. In cold conditions, the gas canister output drops, so keep a spare warm and rotate them as needed.
Select the correct nail size for the timber thickness and structural requirement.
Insert the gas canister into the nailer gas chamber until secure.
Load the nail strip into the magazine with the collation feeding in the correct direction.
Set drive depth using the nailer's adjustment to match timber density.
Test fire two or three nails into scrap timber and adjust depth if needed.
Hold the tool nose firmly against the workpiece before firing to ensure full drive.
Reload before the magazine empties fully to maintain consistent feed.
Rotate gas canisters in cold weather to maintain consistent firing pressure.
Will these nails work with my existing clipped head framing nailer?
Firmahold have tested these nails across all major clipped head framing nailers and they are designed to be compatible with them all. The key requirement is that your tool accepts 34 degree clipped head paper collated nails. If your nailer takes a different collation angle or uses full round head nails, these will not be suitable.
Why do these nails comply with Service Class 3 and what does that mean on site?
Service Class 3 under Eurocode 5 covers timber in exposed outdoor conditions where moisture content is likely to exceed 20 percent. The hot dipped galvanised coating on these nails provides corrosion resistance at the level required for structural fixings in that environment. In practical terms, it means you can use these in roof structures, external framing, and other exposed applications without the nail corroding and compromising the connection over time.
Firmahold Hot Dipped Galvanised Collated Nails are manufactured with a ring shank profile and diamond point tip. The hot dipped galvanising process coats the nail fully in zinc, providing corrosion resistance that meets Service Class 3 requirements under Eurocode 5 for structural timber applications. Paper strip collation at 34 degrees burns cleanly on firing. Available in 51mm x 2.8mm and 63mm x 2.8mm (3300 nails per pack) and 75mm x 3.1mm and 90mm x 3.1mm (2200 nails per pack), each pack includes a compatible gas canister.
