Key Features
- Genuine OEM Hardness and Temper — Manufactured to OEM-specified material grade, delivering the correct spring tension and bite needed to resist fastener loosening under vibration loads typical of pumps and compaction equipment.
- Direct Hardware Match — Sized at 3/4 inch to seat flush against the mating fastener and surface without shimming or adjustment, maintaining correct torque retention from installation.
- Broad Cross-Equipment Fitment — Verified for MQ600H, MQ600HTB, MQ600HTP, MQ600TD80-TLRB, MQ600TD80-TLRP, AR14H, V305EH, V305EK, LS300P, LS300G, LS300GK, LS600P, and C30HDGA.
- Vibration Resistance — The split-ring design bites into both the fastener and mounting surface, maintaining clamp load in high-vibration environments where standard flat washers would allow fasteners to back out.
- Fastener System Integrity — Using the correct OEM lock washer ensures the fastener assembly performs as designed, preventing loosening that could lead to misalignment, leaks, or structural failures in critical assemblies.
A lock washer is a hardened split-ring fastener component placed beneath a nut or bolt head to prevent that fastener from backing out due to vibration or cyclic loading. As the fastener is torqued down, the washer's split ends dig into both the fastener face and the clamped surface, creating mechanical resistance to rotation. In equipment like trash pumps, concrete pumps, and rollers — all of which generate significant vibration during normal operation — even minor fastener loosening can allow components to shift, leak, or fail. Replacing a worn or deformed lock washer with the correct OEM part restores the full clamping integrity of the fastener assembly.
