The Spieth MSW series locknuts are assemblies consisting of locknut bodies and clamping screws. The thread
inside the locknut body is interrupted by a groove, separating the locknut body into a load and a locking part. A
diaphragm connects load and locking part.
3 Assembling Spieth Locknuts
3.1 Preparing for assembly
Remove Spieth locknuts from their packaging right before assembly. As hand perspiration can cause corrosion,
ensure to keep your hands dry and clean and/or to always wear protective gloves for assembly.
Please note:
For environmental reasons, please comply with applicable statutory regulations and guidelines when
disposing of packaging materials.
In case of damage to packaging components, check the locknuts for damage and remove any contamination.
The preservative used is compatible with all conventional machine oils. If in doubt, check the preservative's
compatibility.
For an optimum mode of action of Spieth locknuts, remove the thin wax-like film of preservative from the contact
surfaces using a lint-free cloth. Directly afterwards, use machine oil without friction-reducing additives to lightly
oil the component and protect it from corrosion.
