What is the shear strength of a single Teco nail on an earthquake strap? I realize those straps required multiple nails but I am curious as to just what is the capacity of one nail.
The shear strength of a good quality nail is affected by two factors. The first is the nail diameter, the second factor that is often overlooked is the wood being used. â€œCommonâ€ nails (0.148â€ diameter) are stronger than â€œBoxâ€ nails (0.131â€). 0.131â€ x 1-1/2â€ long Teco nails typically have a shear strength of between 160-180 lbs each depending on the wood they are driven into. 0.148â€ x 1-1/2â€ long Teco nails typically have a shear strength of between 230-250 lbs each depending on wood. Of course the manufacturer of the nail you end up using is the final authority on the exact strength of their nails.
