Black Diamond Micro Stopper Nuts

The Black Diamond Micro Stopper nuts are a set of six tapered nuts that excel in protecting thin cracks and hairline seams. The Micro Stoppers range from 5mm to 10mm in size, and feature a design with a curve on their longest face. This helps them fit into parallel cracks and catch on crystals and irregularities in the rock, much the same as their bigger brothers do. Find out more here Black Diamond Micro Stopper Nuts
