Abstract: Threaded nails, initially used in shoe, automobile and boat industries (Stern 1950a), have expanded into wood and post frame construction markets. Stern (1956) advocated their use in wood construction because of the increased withdrawal strength and extensively researched the use of threaded nails in pallets. Based on post frame construction experience, Geisthardt et al. (1991) reported that published design values for large threaded nails are conservative. It is speculated that the conservative design values result from the lack of experimental data for large nails and spikes and the lack of standardization of thread characteristics. Recently ASTM F1667, Table 45 (ASTM 2006) was modified to standardize the characteristics of annularly threaded nails. The standardization of a specific type of annularly threaded nails, called post-frame ring shank nails, creates the opportunity for both manufacturers and designers to take advantage of the increased withdrawal design capacity of these types of nails. This report details a research study investigating the withdrawal strength of nails manufactured to the ASTM F1667 post-frame ring shank standard.
