Self-locking inserts are threaded fastener elements installed into parent materials — including aluminium alloy, composite laminates, and honeycomb sandwich panels — to provide durable, vibration-resistant thread forms that resist loosening under dynamic loading. They encompass helical wire inserts, key-locking types, and prevailing-torque variants manufactured to MIL-I and NAS standards, installed by press-fit, swaging, or adhesive-bonding methods.
