   With all the proprietary cements, I bet it varies by mfr.

   *My cat's paw tells me that Sterling (made in Illinois) has to be at or near the top of the hand drive list. I like Senco's for guns. Paslodes have offered the least resistance to pull. Went to work for a contractor who immediately belittled the cat's paw in my bags. Less than an hour later, he asked to borrow it; the sheepish look on his face was priceless. To anyone reading this post; how many believe in the advantage of driving nails on an angle?

   *Ryan,I don't know the "science" behind it......but......Just try to pull a few cement coated nails vs regular nails.Who gives a hoot about "science". The proof is in the pulling of the nails.Ed. Williams

   *Sheer strength is the same since the nails are made from the same materials. The pull strength is increased by however much the glue holds. Drive two nails and let them sit for a few minutes, (to allow the glue to cool) then try to pull them out.Rick Tuk

   *I suspect that shear is probably increased too. When a nail fails in shear, it never actually shears off. When a nail fails in shear, it is pulled out of the wood sideways.I would think that the cement would aid in resisting pull out no matter what direction the nail head was being pulled.

   *It is hard to beat a high quality, hot dipped, galvy nail, like those made by Tree Island in Canada. Nails don't shear in wood to wood aplication because of the softness of wood. When a nail is driven through a hanger, true shear failure could occur. Angle variations are subtle but important.Joe

   *Freddy has argued that cement coatings make no difference over time, that they all end up the same. Any experience with this? Does anyone prefer sinkers over regular brights?

   *Gentlemen. Cement-coating a nail can increase and even double its withdrawl resistance Immediately After Driving. The withdrawl resistance can be so great that the heads break while trying to remove the nail. Effective in light woods, they offer no advantage in oak, birch, maple or other hard woods. The high resistance is short lived, however, and in about 30 days the nail's withdrawl resistance is reduced to 50 percent or more.See page 251, What Nails? in my book, _Complete_Building_Construction, 4th Edition published by Macmillan.
