"Due to Squamish’s marine climate all fixed protection should be made of stainless steel. The recommended best practice is that bolts be a minimum of ⅜ inches in diameter and 2½ inches long, made of stainless steel, and designed or certified by the manufacturer with a minimum breaking strength of 22 kN (~5000 lbs). Hangers should also be stainless steel and designed and certified by the manufacturer for climbing with a minimum breaking strength of 22 kN (~5000 lbs)."
