Opis:
3/8' threaded top split shaft bolts are super hard to hammer in and they snapped in tension at 22.52kn and 17.12kn and the snapped in shear at 37.50kn. These bolts were donated by Greg Barnes from the ASCA (http://www.safeclimbing.org/index.htm). Please don't bolt if you don't have to and if you do put in something that will last a long time and not shitty zinc plated split shaft bolts.
