Please note: The part that is driven into the decking is 1 inch to 1.25 inches long. Not the 1.5 inch like it is shown in the photo.
For standard thickness slates. Approximately 80 per pound (2,000 per box). Free shipping in the continental USA (Alaska and Hawaii not included).
Galvanized slate hooks will eventually rust, but if the roof is old and has less than 25 or so years of life remaining, then galvanized slate hooks are a good choice (think barns, or PA black slate roofs). When you need a stronger, tougher, but less expensive slate hook, go with galvanized steel. Blunt points for safety. For roofs with up to 3 inches of headlap. Great for repairing asbestos shingle roofs too.
Stainless and galvanized slate hooks are stronger that copper and will nail into harder roof decking without bending. So if you're nailing into a softwood deck, copper hooks are fine. If the deck is harder, use stainless steel or galvanized slate hooks.
We also have copper slate hooks, stainless steel slate hooks, and over-sized slate hooks for thicker slates and ceramic tiles.
