Your D-connector panel mount is a few millimetres short and the stock nuts won't reach. These 6 mm hex nut extenders add the extra thread length you need so the connector seats properly against the panel face. Eight pairs (16 pieces) means you've got enough for a full build or a batch of repairs without running a second trip to the bench. Fit, tighten, and the connection holds
