Spiral nail is a construction nail with a twisted, spiral‑profiled body that rotates into the wood fibers when driven, creating an exceptionally strong mechanical joint.
Type:
Spiral nail (twisted body)
Material:
High‑quality steel
Usage:
Manual hammering or pneumatic nailer
Available dimensions:
3,1 × 70 mm
3,4 × 70 mm
Packaging:
1 kg
2,5 kg
5 kg
This design provides grip up to 3 times stronger than a smooth nail joint, making it ideal for massive structures, load‑bearing assemblies, joints exposed to vibrations, and elements where it is crucial that the nail remains immovable over time.
The spiral body works on the principle of a screw – as it is driven in, it penetrates the wooden structure and locks firmly, reducing the possibility of pulling out and loosening of the joint. It is made of high‑quality steel and additionally processed by tumbling and cleaning, resulting in a uniform surface without edges and easier installation with manual or pneumatic tools.
This nail is used as an alternative to screws in cases where high holding force is required, but without pre‑drilling or additional reinforcement of the joint.
– Type: spiral construction nail (twisted body)
– Construction: spiral profile – maximum friction and holding
– Material: high‑strength quality steel
– Processing: tumbling + cleaning (smooth surface, no sharp edges)
– Surface: natural steel (without zinc)
– Head: flat, suitable for countersinking into material
– Tip: sharp, quickly penetrates wood and initiates spiral insertion
– Installation: manual or pneumatic tools, depending on equipment
The spiral nail is recommended in systems requiring high load capacity, resistance to pulling out, and prevention of joint loosening. An ideal solution for elements exposed to load, impacts, humidity changes, or vibration.
Most common applications:
Construction and structures
– massive wooden structures
– rafters, battens, substructures, and roofing systems
– joints bearing weight or working under load
– prefab assembly and façade systems
Industry and packaging
– heavy‑duty pallets
– crates, boxes, and transport packaging
– industrial assembly and wooden unit construction
Carpentry and assembly
– furniture structures under high stress
– permanent joints that must not loosen
– combination with adhesives for maximum strength
Professional and household use
– interior and construction works
– panel and substructure installation
– replacement for screws in many cases requiring speed and holding
– spiral profile holds 2–3 times stronger than smooth nails
– twisting into wood fibers prevents pulling out and loosening
– especially resistant to vibration and dynamic load
– works like a screw without the need for pre‑drilling
– professionally tumbled and cleaned – easy driving
– suitable for structures, pallets, industrial assembly
– produced in 70 mm length for deep, secure fixation
