Colin Chapman of Henkel, makers of Loctite brand products, says that adhesives are the key to removing an age-old problem. Vibration is a fact of life. It has caused bolts to work loose since threaded joints first came into existence, and many and varied - often ingenuous - methods of resolving the problem have been tried. Yet of all the processes that have been trial led, one of the most successful has centred on the application of adhesives. Indeed, it was the very problem of vibration that led Dr Vernon Krieble - the pioneer of Loctite adhesives - to set about finding a satisfactory way to lock and seal a threaded component.
