One of my viewers contacted me about an issue he was having with the installation of a set of NTN bearings.
He purchased what he believed to be Loctite 641 from an online supplier, this was promptly delivered with a label indicating it to be “high strength”. This is incorrect as high strength Loctite is 638.
This Loctite was confirmed to be counterfeit by Henkel.
The photograph above shows the counterfeit Loctite. The quality of the packaging and label is an almost exact copy, it’s only the mislabelling that causes suspicion.
