Note:
The self-limiting bolt-locking washers guarantee that bolted joints exposed to transverse stresses, oscillations and vibration will be safe from loosening. A joint is also secure at low levels of tension. If the bolt (nut) tends to loosen independently in bolted joints under dynamic stress, the bolt (nut) carries its positive-locking washer with it, the sloped surfaces of which run directly up against the slpoed surfaces of the counter-washer. In other words, the nore a bolted joint "tries" to loosen itself, the more securely the wedge action of the washer blocks the attempt.

Supplied glued as a pair.
