The weight per unit length of 3 coil nails can vary depending on factors such as the diameter, length, and material composition of the nails.

However, as an estimate:

For a common size like 3-inch (76mm) length and 0.120-inch (3.05mm) diameter coil nails commonly used in construction applications, the weight per unit length is approximately:

  • Weight per unit length (3-inch coil nails) ≈ Total weight of a coil ÷ Total length of nails in the coil

To calculate this accurately, you would need to know the weight of a full coil of 3-inch nails and the total length of nails in the coil.

The weight of a coil of nails can vary based on factors such as the nail material (usually steel), coating type, 3 coil nails and packaging method. Similarly, the total length of nails in the coil depends on the number of nails and their individual lengths.

Manufacturers or suppliers typically provide specifications for their coil nails, including the weight of a coil and the total length of nails in the coil, which can be used to determine the weight per unit length of the nails.
