Nail Spacing Recommendations for APA EWS Rim Boards and I-joists

If nails are spaced too closely, the risk of splits in the rim board and I-joist flange increases. This publication provides nail spacing recommendations (tables and diagrams) for APA EWS Rim Boards and I-joists. These recommendations are based on the closest distance between nails that can be allowed while minimizing splits.

This publication is designed for: builders, contractors

These recommendations are usually adequate for conventional construction (one-and two-family dwellings) and some commercial and multi-family applications, but they may not be adequate for all applications.
