Source of issue –Quality
Description –
Alan from Marlin Marine in Airlie Beach rang. One of his customers returned a CDZ4-225 as 2 of the screws were stuck. He managed to remove them, but the threads were damaged and he had to re-thread them. He was not overly concerned as he was able to put the anode back on the shelf after it was re-threaded for re-sale.
He just wanted to let us know, as it was the third time it had occurred over the past 18 months.
Immediate action –No immediate action required. Alan rectified it with his customer.
Root cause –Customer may have over-tightened.
Corrective action –
Although some customers may over-tighten the screws, it still occurred more frequently than it should have.
This issue will no longer occur with the CDZ4-225 and the CDZ4-250, as the tooling has been modified so that the screw threads into a nut on the other anode half, rather than into the zinc. We are working through our range to replace the shaft anodes with screws that thread into the zinc. It is a slow and costly exercise, so we are progressing slowly.
