Slide 57 of 67
- Common nails versus other nail types
- Common nails are thicker than box, cooler or sinker nails and are therefore strongest and stiffest.
- Common nails have larger nail shank diameters than other nails.
- Common nails are always specified for shear wall panels
- Although hot-dip galvanized box nails may be used for plywood sidings, use only common nails for wood structural panel shear walls.
- The figure shows the box label for the nails that should be used
- When you order gun nails, you must specify: 3 x 148 (shown on box)
- Watch out for gun nail boxes:
- Hand driven nails typically come in boxes labeled with the nail type.
- Boxes with nails for nail guns sometimes show only the length, diameter and finish.
- To verify the use of common nails, contractors and building inspectors must be familiar with nail diameter requirements.
- For example, if a gun nail box says 2-3/8 x.113 Smooth instead of 2-3/8 x.131 Smooth, the fastener is an 8d cooler nail instead of the 8d common. This is a common construction error.
- Sometimes phony boxes are left at a site to sidetrack an inspector - Learn to recognize nails
- Often contractors may want to cut corners on nails and use less expensive nails – do not cut corners.
- Nail sizes and diameters are shown in the Appendix.
