To guarantee quality in your post-frame construction, the devil is in the details. The use of nails versus screws in your building is a perfect example. Knowing when, where, and why each fastener should be used is yet another step toward assuring you get the most bang for your buck.
Screws, without a doubt, provide a more secure connection. Nails, however, are less expensive and faster when using nail guns. Both screws and nails have their place in post-frame:
1. Wood-to-wood (using nails “under” the steel): Whether you’re applying nails or screws, the goal is to provide enough shear strength to support wind and snow loads. Nails, when applied in the correct manner and number, can provide the necessary strength. They are best used in three specific areas “under” the steel that wraps the structure: girts to columns, purlins to trusses, and bracing.
2. Steel-to-wood (securing your steel structure): Always use screws to attach your exterior steel siding to a structure. Standard steel siding screws provide over twice as much pullout resistance as nails.
