Product Description

The sp126-e is a flat washer sized for 1/4-28 UNF fasteners, conforming to AN960/NAS1149 specifications. This steel washer distributes clamp load under bolt heads and nuts, protecting underlying surfaces from bearing stress during assembly. Installed in airframe bracket attachments and structural connections where 1/4-28 hardware is specified.

The washer prevents fastener heads from sinking into softer materials and reduces stress concentration at attachment points. Verify size against the aircraft's Illustrated Parts Catalog and apply torque per the applicable maintenance manual.
