When this post first came out I went to my local O'Reilly but they did not have this drain plug tool in stock. I asked if they could order it but they said it was discontinued by the supplier.
That was no big deal because I ended up making my own drain plug tool like EA #3538 did in this post:
Home-made ZF Drain Plug Tool Interestingly, I was at my local Harbor Freight the other day and needed a 6mm hex head socket for my Pantera project. I went ahead and purchased this set for $10.40 (after my 20% coupon – which you can find in almost any magazine). When I arrived home and looked closer at the set I noticed that there was a 17mm hex head socket in the set which is exactly the right size for the ZF drain plug.
So if your looking for a ZF drain plug tool and need some other metric hex head sockets the price really can’t be beat.
