Lifespan
Bolts degrade over time — particularly in coastal areas from salt, but also from stress corrosion cracking — and eventually, all sport climbs need to be re-fitted after a number of years.[2][3] The highest quality titanium bolts are too expensive to use regularly, and the next highest quality stainless steel bolts have an expected lifespan of circa 20—25 years (the cheaper plated stainless steel bolts have a shorter span); and in 2015, the American Alpine Club established an "anchor replacement fund" to help replace the bolts on America's estimated 60,000 sport climbing routes.[4]
