Retaining washer | Locking mechanism | Plastic or metal component
Retaining washer The retaining washer captively holds the locking bolt to the cover. The maximum cover height describes the position of the retaining washer on the bolt. Thinner covers allow movement. To achieve self-insertion when pressing the cover, the actual cover height must be the maximum cover height.
Lock bottom – receptacle The first step is to choose the receptacle because it affects the grip length.
Grip length The following parameters are added to determine the grip length:
grip length min = over height** + retaining washer (thickness)*** + 0,7 mm + possible cover spacing
**The cover height must fit precisely. ***With a given cover spacing, the thickness of the retaining washer is already included in the cover spacing.
Grip lengths vary depending on the receptacle. A + 1.5 mm tolerance can be added to the indicated nominal
dimension. Within this tolerance, a noise-free fit of the cover in the housing is guaranteed.
Functional length Measurable dimension on the bolt. The dimension results from the above-named lengths. It helps to distinguish the bolts.
