BOLT LOCKING SYSTEMS: LOAD WASHERS
The term load washers
These SCHNORR® load washers have been specially designed for high-strength bolts up to a strength class 8.8 to 10.9 acc. to DIN ISO 898 part 1. This represents the most powerful form of safety washer in the form of a disc spring.
These load washers conform to DIN 6796 and are designed for high demands on the protection of bolt joints. As a highly progressive load increase occurs at the end of the spring deflection when the washer is flattened the load has been indicated as double the calculated value. Tests have shown that these values are comparable with the measured values.
For the protection of bolted joints only that load is available which remains after the washer has initially set. The table in our brochure indicates the respective minimum height after the initial loading of the washer. Thus the maximum loss of height due to setting is limited.
Particular advantages of the SCHNORR® Load Washer
- High axial load
- Optimum compensation for setting in the joint
- Reduction of the dynamic loading of the screw due to higher elasticity of the joint
- Uniform concentric loading and high safety through a high degree of spring action
- Suitable for captive fitting on a wide range of bolts (Combi-Bolts)
