Description –
Customer (Marine Plus) emailed to say that their customer has had problems fitting the CDA9-025B anode. Their attaching bolt is bottoming out before it gets tight. DF checked the anodes compared to the zinc version CDZ9-025B and there is a 2mm difference in recess. I have advised Marine Plus that using a washer would work, but its sounded like their customer doesn't want to use a washer.
Immediate action –Offiered to replace with a checked anode to have the smallest recess, let him know a washer or sanding down his bolt by 2mm would work.
Root cause –13AUG26: Helen from Metal Distributors replied, "Processing/Secondary Department made an error and machined the counterbore too deep"
Corrective action –
No Corrective Action was offered by Metal Distributors. No apology and no indication provided on steps put in place to prevent future re-occurance. DF checked agin with MD Aug 26. Only got a 2 line answer that wasn't very helpful. See email chain Outlook, sales@cathodicanodes.com 13/08/26 Sales Desk Metal Distributors.
Verification –DF to check if other Anodes have same problem, Only one customer complaned, they may have been using the incorrect anode causing the 2mm difference to be a problem.
