Testing was done a few years ago on the different types of bolts and it was found that on slab, vertical or slightly overhanging routes the stainless steel Hilti HSA-KR M10x110mm can be used. Please note that for anchors of multi-pitch routes or steep routes these bolts will not be strong enough. Either the M12x110mm bolt or the Upat UKA3 glue-in capsule with 100mm stainless threaded bolts can be used. Almost all of the other glue's and readily available bolts were tested and not always found to be sufficient. Please take extra care in testing where you place your bolts as there are many hollow sections of rock. Remember that when you bolt a route you do not own the rock, and that many others would also like to climb it, so bolt it for everyone and not only yourself. Some of the routes are still bolted with unrated U-bolts and some dodgy placements can be found, but for the most part all routes are safe. If you would like more information about bolting in this area please contact the Mountain Club of South Africa.
