High compressive loads during make-up of non-magnetic drill string components have a tendency to cause galling and scuffing on rotary shoulders and thread flanks. Upon breaking-out the connection, galled areas are forced to separate leading to severe damage of the thread flanks and/or rotary shoulders. Re-cutting is costly and can be limited especially with bottom-hole assemblies having stress relief grooves or due to logistics (copper plating of fresh threads at the remote drilling sites).
