Nail length, projection and travel: three different dimensions
В мені · VMENI · Updated · 2 min read
A nail’s total length, its projection above the base and its permitted movement are three separate dimensions. “30 mm nails” does not mean 30 mm is exposed. Nail height also does not determine spacing: tall and low designs may have the same distance between nails.
Which dimension are you reading?
Part of a nail sits inside the base or mechanism. Total length describes the component, while projection describes its exposed section. A floating design also needs a stated travel range. Do not substitute one measurement for another.
Is a taller nail better?
There is no universal height for all constructions. Assess the projection together with fastening, consistent contact heights and the movement mechanism. Greater length is not evidence of greater benefit. A very low projection may alter contact with the base; the product instructions should explain the intended arrangement.
Why consistent height matters
In a fixed board, one notably taller nail can take load before its neighbours. In a floating board, intended travel is different from sticking or falling out. Inspect without pressing skin onto the tips.
Diameter does not describe the whole tip
Identical shaft diameters can have different tip profiles and finishing. Burrs or damage matter too. Grinding or cutting a part yourself may change its height and geometry; discuss repairs with the manufacturer.
What a useful specification contains
Look for total length, exposed projection and, for a moving design, permitted travel separately. For replacement, the component must fit the fastening and mechanism of the actual model, not just match one length.
