Mag Survey Nail From 25mm To 50mm Boxes Of 100
Mag nails, are used for land surveying and construction layout when critical points are needed to be set in asphalt, wood, or other surfaces that a nail could be set into.
Since most of the points that are set, end up in the real world, we have to be able to visually find them in the future.
In addition the points set by one particular surveyor may need to be recovered by another Surveyor.
Hardened MAG Nails have become the preferred nail among surveyors worldwide.
