The Nord-Lock Standard Washer Kit Delta Protekt is an M6 to M20 assortment of wedge-locking washer pairs in Delta Protekt finish, built for vibration-resistant bolted joints in mining, rail, heavy plant and renewable energy where bolt loosening cannot be tolerated.
Heavy Industry and Mining
- Crushing, screening and conveying equipment where vibration is constant and re-torquing is impractical
- Pump and motor base-plate fastening in processing plants
- Mine site structures and chutes subject to dynamic load
- Heavy plant and machinery requiring preload retention over long service intervals
Rail and Transport Infrastructure
- Rolling stock bolted joints exposed to continuous vibration and dynamic loading
- Rail track mounting and clamp assemblies
- Bridge and overpass structural connections requiring long-term preload retention
- Transport equipment maintenance kits covering M6 to M20 bolt sizes
Wind Energy and Renewables
- Tower flange and nacelle bolted connections in wind turbines
- Solar racking and mounting structures subject to wind load and thermal cycling
- Renewable energy infrastructure requiring vibration and slackening resistance
Structural and Civil Engineering
- Critical structural steel connections where loosening cannot be tolerated
- Suspended walkways, mezzanines and platforms under dynamic load
- Bolted steel frame connections in seismic design zones
General Industrial Maintenance
- Assortment kit for MRO teams covering the most common metric bolt sizes
- Vibration-prone production machinery and presses
- Predictive maintenance programs reducing unplanned downtime from fastener loosening
