Dead on 8mm with good fixing. Clamps bars together perfectly; very well made and will buy again when needed.

*by M***O on Reviewed in Italy on 15 May 2024*

Il giunto con foro di diametro 6,35mm è perfetto per la soluzione che avevo previsto che in pratica era un'allungamento di un alberino di potenziometro di pari diametro.
