Aluminum Nail Views
I recently built myself a set of nail stakes on my metal lathe using 7075-T6 Aluminum. They are 6?" long, have a .2154" diameter shaft, .35o" diameter head and weigh a little over 10grams. I drilled a 1.5mm cross hole and attached a piece of 1mm cord for a tie-out loop. Think solid Easton nail stake with a head that cannot come off. They are equal in bending strength and weight. They work so well that I am considering mass producing them. Before I move forward and have 5,000 of these built I would like to know if there is any interest. I would like to retail them for $1.00 a piece which is half the price of an Easton nail stake. I was thinking of anodizing them Red so they would be hard to loose.
I am not sure if any manufacturer would/has ever said the grade aluminum they use for gutter nails/spikes but I am sure its on the cheap side. My guess is something around 30,000 psi since gutter spikes will bend pretty easily while my 7075-T6 stakes are hard to bend and are something like 83,000 psi.
Aluminum siding features nailing slots that run along the top of it. The slots allow the siding to slide over the nail during temperature changes which can cause the material to expand, retract and bind. Binding can cause siding to become wavy or damaged. The most common way to secure siding to a building is by using aluminum nails. The aluminum nails' penetration depth should be at least a#xBE; of an inch in solid lumber and 5#xBD; inch in plywood.
