FAQ

What does the ‘CK’ designation on the box signify?

While not explicitly defined, ‘CK’ in this context likely stands for ‘Countersunk Head’ (‘Cilinderkop’ in Dutch), indicating the nail head is designed to sit flush with or slightly below the material surface for a clean finish.

Are these nails suitable for outdoor applications?

Yes, the zinc-plating provides a protective layer against rust and corrosion, making them suitable for many outdoor uses where they are not exposed to constant moisture or harsh chemicals.

Is a pilot hole required when using these nails in hard concrete?

For most brickwork and softer concrete, a pilot hole is not necessary. However, for very hard, dense concrete, drilling a small pilot hole (e.g., 2mm) can prevent the concrete from cracking and make driving the nail easier.
