Key Features

• Genuine OEM Material Specification — Manufactured to the exact hardness and spring-tension rating required for fastener retention in DCA-series generator assemblies, ensuring the lock function performs as engineered.
• Drop-In Installation — Matches the original bolt diameter and seating profile, so it installs directly in place of the worn or damaged washer without modification.
• Broad DCA Generator Fitment — Compatible across a wide range of Multiquip ultra-silent and super-silent generator models including DCA400SSI, DCA300SSK, DCA400SSK, DCA600SSK, DCA800SSK, DCA800SSK2, DCA1100SSC, and Tier 4 variants.
• Prevents Fastener Back-Out — The locking action resists loosening caused by engine vibration and thermal cycling, which is especially critical in high-cycle generator applications where fastener movement can lead to misalignment or component damage.
• Electrical Safety Compliance — Proper fastener torque retention is essential in generator enclosures where loose connections present both mechanical and electrical hazards; using the correct OEM Lock Washer supports safe ongoing operation.

A lock washer is a hardened fastening component placed beneath a nut or bolt head to resist rotational loosening under vibration, load cycling, and temperature change. In a diesel generator like the DCA series, mechanical vibration from the engine and alternator is constant during operation, making reliable fastener retention critical throughout the enclosure, mounting frame, and electrical connection points. When a lock washer loses its spring tension or is missing entirely, fasteners can gradually back out, leading to loose components, misaligned assemblies, or unsafe electrical connections that may cause equipment damage or operational failure.
