ChrisNik MAG Nails are designed for land surveying and construction layout applications where critical points need to be set in asphalt, wood, or other surfaces that can accept a nail. These hardened magnetic survey nails are built for durability, visibility, and easier future recovery of field-set points.

Because many survey points remain in place in real-world conditions, they must be recoverable later by the original surveyor or another surveyor returning to the site. The magnetically enhanced design helps make points easier to locate below the surface, which has made MAG Nails a preferred choice among surveyors worldwide.

Key Features

• Magnetically enhanced design helps make buried points easier to locate
• Larger center point helps with accurate rod point placement in the center of the nail
• Hardened, durable material helps reduce the risk of the head breaking off during installation
• Zinc plated for improved corrosion resistance
• ROHS European compliant
• Coated with environmentally friendly zinc and clear chromate
• Replacement for PK or Parker Kalon (PK) nails
• Predecessor to the DWSITEPRO Hi-Magnetic Masonry Nails
• Made in the USA

Common Applications

• Land surveying control points
• Construction layout marking
• Permanent or semi-permanent point marking in asphalt
• Point marking in wood and similar jobsite surfaces
• Pre-drilled concrete point marking

Suggested Size Selection

• 3/4" x 1/8" - Common choice for concrete and other pre-drilled hard-surface applications where a smaller nail is preferred.
• 1" x 5/32" and 1-1/4" x 3/16" - Good mid-range options for lighter hard-surface work or smaller drilled holes.
• 1-1/2" x 1/4" and 2" x 1/4" - Versatile general-purpose sizes for survey and layout work in asphalt, wood, and similar surfaces.
• 2-1/2" x 1/4" - Popular choice for asphalt applications where additional holding power is preferred.
• 3-1/2" x 1/4" - Longest option for applications where deeper embedment is desired.

Application Notes

• For concrete installations, pre-drilling is recommended.
• Use a 3/16" masonry drill bit for the 1-1/4" MAG Nail.
• Use a 1/4" masonry drill bit for the 1-1/2", 2", 2-1/2", and 3-1/2" MAG Nail sizes.
• Size recommendations above reflect common field practice and jobsite preference.
