Our Apex stakes are made from aerospace grade 7075 T-6 Aluminum which is one of the strongest aluminum alloys made. We originally designed these stakes to be used in soft soils, sand, light snow, forest duff, etc. but they are so tough and burly that you can drive them through the hardest rockiest soil you will encounter and they will hold like a pitbull. They also feature side cut outs at the half way point so you can tie cordage around the middle and bury the stakes in sand and snow. Size: 7.5" long x .90" wide, Weight: .55oz (15 grams). Proudly made by us, right here in the USA.
