Conical elastic sperrkant washers


Conical elastic Sperrkant washers range has been designed to create an elastic pre-load in a bolted-joint connection so as to reduce risk of unwanted loosening.
Growermetal’s conical elastic Sperrkant washers range is ideal in applications requiring vibration resistance and parts subject to temperature variations.
The combination of the conical geometry and the “sperrkant” radial ribs on the washer’s upper surface provide a high resistance to loosening of the bolted connection whilst avoiding damage to the bearing surface.
The broad Growermetal’s conical elastic Sperrkant range include washers ideal for application with hexagonal bolt head screws, flanged bolt head or oversized holes and socket head screws.
Conical elastic Sperrkant washers are normally used with bolt of property class 6.8 and 8.8.
