Vibration resistance with range of washers

The team working at Challenge Europe are experts at exploiting the adaptability of simple, rugged threaded fasteners, and it is this adaptability which brings engineers to their use. Simple to use and to provide with vibration resistance, improved sealing, load spreading or good looks by combining with a range of washer accessories to enhance the performance of the basic fastener.

Crinkle, wavy washers, coil spring washers and serrated tooth lock washers each offer anti-vibration resistance in varying degrees whilst two-piece wedge lock washers such as Nord Lock provide a much greater resistance to vibration loosening. Belleville washers provide a combined profile of characteristics by offering continuous load anti-vibration and cushioning effects.

Where liquid control is required, then a sealing ring of some sort is usually called for, often in nylon, fibre or rubber, or perhaps a composite bonded type like a Dowty washer. More specialist items such as Dubo Ring washers extend liquid sealing into pressure retention, combined with vibration resistance.

Challenge Europe are often called upon to accessorise for a decorative finish, frequently with a soft or even fragile substrate and find that something as low tech as a cup washer fits the bill in attractive finish and providing a light load spreading function.
