Zinc dip and Loctite 262 can they work together?



Does hot dip galvanizing negate the use of Loctite 262 with steel nuts and bolts?

We intended to use Loctite 262 to permanently secure the axles into the frames of our hot-dipped galvanized utility carts.

The frame contains a receiving nut for the axlel, which is a #5 grade shoulder bolts with 13 threads per inch. The nuts are in the frame prior to the dipping. They are then tapped to remove the zinc galvanizing. We apply the Loctite to both the bolt and the nut. The problem is that after 48 hours and even after 72 hours the Loctite does not cure.

I am a rank amateur. Can anyone shed light on this situation?

Anaerobic adhesives require a chemically active surface to cure. The plating may not provide that. Suppliers of such adhesives typically also include a primer that substitutes for surface reactivity.
