We made a fresh batch of our famous Beech Connectors. This time we standardized the spacing of the threaded holes (1.25″ center to center) to facilitate mallet head switching. As usual the connectors are made from 7075 aluminum rod and grade 12.9, M5, countersunk (flat head), socket head cap screws. We use only the finest ingredients for you. So far we have not had one report of a failure with any of the connectors that we have made so they seem to be working well for people. Anyway they cost $5 each and we have a good supply of them for now. Marco!
