Practically every engineering product with any degree of complexity uses threaded fasteners. A key advantage of threaded fasteners over the majority of other joining methods is that they can be dis-assembled and re-used. This feature is often the reason why threaded fasteners are used in preference to other joining methods and they often play a vital role in maintaining a product's structural integrity. However, they are also a significant source of problems in machinery and other assemblies. The reasons for such problems are due, in part, to them unintentionally self-loosening.
Fasteners coming loose is a common
problem across many industries. We can complete an assessment
of a fastenerís self loosening characteristics using a transverse
vibration test machine (often referred to as a Junker machine
and the the test performed, a Junker Vibration Test). The fastener
preload decay graphs produced can allow an assessment to be
made of a fastenerís resistance to self-loosening. The test
can be performed on the locking mechanism forming part of a
nut (such as with nylon insert nuts), on a bolt (such as bolts
with a nylon coated patch on the bolt) or a washer (such as
a helical spring lock washer).
