The principle advantage of male bolts is that the hole drilled is the same as the bolt diameter, which takes about 40% less energy (or battery power) than drilling a hole for same-sized self-drilling anchor.
Stainless steel sleeve ensures a much longer life in comparison to the competition.
Nuts and washers included. 8-mm bolts are for caving use only; 10-mm and larger may be used for climbing.
Sold in sets of 10.
