The Black Diamond 1/2 inch Baby Angle Piton CAN be used for drilled anchors in sandstone. Good to have for emergencies, as they place fairly well in rock that is too soft for actual expansion bolts. Heavy though. Kinda fits in a 3/8 inch hole. Weight: 68 grams or 2.4 ounces.

Expert knowledge required to use this item. Be careful out there.
