Preventing Wood Splitting: Why Blunt Nails Are the Ultimate Solution
When working with timber, choosing the right fastener is critical. For professionals in fencing, joinery, and carpentry, wood splitting can compromise both the strength and appearance of a project. Fragile timber can crack under a nail, but the solution is often simpler than expected: blunt collated fastenings used with air tools.
Using the right coil nailer and collated fastenings not only reduces the risk of timber splitting but also improves project efficiency and gives a cleaner, more professional finish. These fasteners are ideal for joinery, carpentry, and fencing applications where speed, accuracy, and durability matter.
Why Does Wood Split?
Wood naturally contains grains and fibres running along its length. When a sharp-pointed fastener is driven in, it forces the fibres apart, creating outward pressure. Thin or brittle timbers, such as feather-edge boards, are particularly prone to splitting, weakening the structure and leaving visible cracks.
Splitting is especially troublesome in fencing and fine woodworking, where both structural integrity and visual appeal are important.
How Blunt Collated Fastenings Protect Timber
Blunt fastenings have a flattened or slightly rounded tip. This design changes how they interact with timber, reducing the risk of splitting while increasing holding power.
Less Splitting
Instead of tearing through wood fibres, blunt collated fastenings displace them, minimising outward pressure and preventing cracks, especially in delicate or thin timber boards.
Stronger Hold
Blunt collated fastenings compress wood fibres rather than severing them, creating a tighter grip. This results in a more secure fix that withstands stress and improves project longevity.
Cleaner Finish
Sharp fasteners can leave visible puncture marks, while blunt fastenings leave a smoother, cleaner surface. This is important for joinery, fencing, and other timber projects where appearance matters.
Choosing the Right Blunt Collated Fastenings
Blunt collated fastenings come in different types, shank styles, and finishes. Choosing the right ones depends on the timber, project type, and environment.
Shank Type
-
Ring shank fastenings are ideal for fencing and outdoor projects because they offer excellent grip.
-
Screw shank fastenings provide superior holding power for structural work.
-
Plain shank fastenings are easier to remove and suitable for temporary fixes.
Size and Gauge
Correct length and thickness are crucial. Smaller collated fastenings work well for fencing, while longer, thicker fastenings are better for heavier-duty joinery or carpentry projects.
Finish and Corrosion Resistance
-
Bright steel fastenings are suitable for indoor work.
-
Galvanised fastenings resist rust and are ideal for most outdoor applications.
-
Stainless steel fastenings offer maximum corrosion resistance for coastal or high-moisture environments.
The Smart Choice for Professionals
If timber splitting is a frequent challenge, using blunt collated fastenings with air tools is an effective solution. They reduce damage, increase holding power, and help projects last longer.
Blunt collated fastenings save time, improve finishes, and deliver professional results for joinery, fencing, and carpentry.
