Genuine Plain Washer (Part #WP-0370316-SD). This authentic OEM precision washer is designed for use across Juki MO-series overlockers and DDL-series lockstitch machines to provide a secure and vibration-resistant seating for mounting bolts and screws.

Key Features & Benefits
100% Genuine Juki Quality: Manufactured to Juki’s exact industrial tolerances. Unlike generic hardware store washers, the WP-0370316-SD is crafted from a high-tensile alloy that resists deformation under the heavy clamping forces of a 7,000+ SPM (stitches per minute) production environment.

Uniform Load Distribution: Specifically engineered to provide a perfectly flat and even surface, preventing mounting screws from digging into or damaging sensitive machine castings and brackets.

Vibration Dampening: Acting as a critical interface between the screw head and the machine frame, this washer helps to absorb high-frequency mechanical pulses, significantly reducing the risk of a fastener backing out during operation.
