Bolted joints underneath your 4x4 need to withstand stresses from multiple fronts - loosening due to vibration (off-road corrugations), loosening due to dynamic loads (off-road flexing and impacts) as well as slackening due to settlement and relaxation.

Utilising a unique multifunctional design, Nord-Lock® X-Series Washers offer the highest security against bolt loosening and slackening. Combining Nord-Lock’s unrivaled wedge-effect solution (to prevent spontaneous loosening) with an exceptional spring effect (to compensate for loss of preload due to slackening), Nord-Lock® X-Series Washers give you a total security option for those situations in which there can be no compromise.
