Abstract
A pallet size nail having a comparatively small gauge shank whose surface is pitted with contiguous minute pits bounded by small sharply shaped wall convexities as provided by grit blasting the surface with approximately 80 mesh grit of aluminum oxide, which protuberances imbed in wood fibers and provide a substantial increase in holding power against withdrawal compared with sandblasted nail shanks, the nail preferably being spirally fluted.
