Product Description
The AN525-10R4 is a steel washer-head machine screw with a #10-32 UNF thread and cross-recess drive. The broad washer head distributes load across aluminum skins and composite surfaces, preventing fastener pull-through during installation. This screw secures inspection panels, access covers, and removable components in aircraft structures.
Installation requires torque control per the aircraft maintenance manual to prevent over-tightening and material damage. Verify dash-length selection matches the panel thickness and underlying structure before assembly.
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.
