1. Main Parameters of Coil Nails
To ensure accuracy in measuring coil nails, it is essential to understand their key parameters:
Diameter: The thickness of the nail shank.
Length: The distance from the nail head to the tip.
Head Diameter: The width of the nail head.
Coil Diameter: The overall diameter of the coiled nails.
Angle: The angle between the nails in the coil, usually 15° or 16°.
Number of Nails per Coil: The total number of nails in one coil, commonly 200-400 nails.
2. Measurement Methods
Nail Length Measurement: Use a caliper or ruler to measure from the bottom of the nail head to the tip. Ensure the nail is placed straight for accuracy.
Shank Diameter Measurement: Use a micrometer or caliper to measure the nail shank at the center to avoid errors from surface irregularities.
Head Diameter Measurement: Use a caliper to measure across the widest part of the nail head.
Coil Diameter Measurement: Measure the outer diameter of the coiled nails with a ruler or tape measure.
Angle Measurement: Use a protractor or refer to product specifications to confirm the nail collation angle.
3. Precautions
Ensure the measuring tools are calibrated to avoid deviations.
Measure multiple samples and take the average value to reduce errors.
- When measuring the coil diameter, keep the coil in its natural shape without stretching or compressing it.
- Store nails in a dry environment to prevent rust, which may affect measurement accuracy.
- Follow standard industry specifications (e.g., EN, ASTM) for precise measurements.
By following these methods and precautions, you can ensure accurate coil nail measurements, which helps maintain quality control and compatibility with nail guns.
