Title	Part 21 - Bolts Provided Without Zinc Plating
Event Description	The following information was provided by Emerson via fax: A deficiency was identified in Rosemount 3153N series pressure transmitters with Rosemount 3159 remote seals with the LG1 option. The remote seal bolts in this single manufacturing lot were lacking the zinc-plating specified for corrosion resistance. Non-conforming bolts in Emerson inventory have been returned to the vendor for zinc-plating. Backlogged orders were confirmed to have correct zinc-plating. Rosemount recommends end users evaluate the significance of this notice to their specific pressure transmitter applications and environments. Rosemount further recommends that end users replace the un-plated bolts in susceptible applications to mitigate the potential for corrosion induced failure over time. Contact Information: Gerard Hanson, Vice President and General Manager of Rosemount Nuclear Instruments, Inc. (952-949-5200) Affected plants: LaSalle and Dresden
