Key Features

  • Genuine OEM Material Grade — Manufactured to the exact hardness and spring tension spec required for secure fastener locking in drill rig and core drill assemblies.
  • Drop-In Hardware Replacement — 5 MM sizing installs directly into existing fastener positions without reworking surrounding hardware.
  • Confirmed Fitment — Compatible with DM15A9C and CDM2CSA models; use your model code to verify before ordering.
  • Prevents Fastener Loosening Under Vibration — Lock washers in high-vibration drilling equipment are critical to keeping fastened joints secure during operation; a worn or missing washer allows joint creep and mechanical failure.
  • Safety-Critical Hardware — Fastener integrity on drill rig stands and core drill frames directly affects structural stability during operation; using the correct OEM washer maintains the designed clamping load.

A lock washer is a small but essential piece of hardware placed under a nut or bolt head to resist loosening caused by vibration, torque, and dynamic loading. In drilling equipment like core drills and drill rig stands, where vibration is continuous and clamping loads are high, a lock washer maintains the tension in a fastened joint and prevents the fastener from backing out over time. When a lock washer is missing, deformed, or incorrect in size, fasteners can work loose gradually, leading to misalignment, structural instability, or component damage that far exceeds the cost of the washer itself.
