Conventional nuts don't sit well in flared cracks, which is why the Alloy Offset was invented designed. The DMM offsets have the wire protected by a full radius recess and have holes drilled in to reduce its weight without affecting its stopping power. On slightly flared placements nothing fits like an Offset. Get a set as a back up for your Wallnuts and prepare to be converted.
