Product Description

The sp55b is a steel double-coil spring washer designed for 4 BA screws in aircraft fastening applications. This washer resists vibration-induced loosening by maintaining clamp load under operational stress. Install directly under the screw head or nut to distribute pressure across a wider surface area and prevent fastener rotation.

BA thread sizes follow British Standards specifications for small-diameter precision fasteners. Verify washer compatibility with your aircraft's Illustrated Parts Catalog and follow maintenance manual torque guidance during installation to ensure proper load retention.

Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
