Product Description
The NAS1189-3P4 is a self-locking, 100-degree countersunk screw manufactured from alloy steel with UNJ threads conforming to NAS1189 aerospace fastener specifications. The screw features a built-in locking patch that provides vibration resistance without requiring separate locknuts. Designed for flush attachment of aircraft access panels, skin fastening, and structural applications where a low-profile head is essential.
The countersunk design allows the screw head to sit flush with panel surfaces, maintaining aerodynamic contour and reducing snag hazards. Installation requires torquing per aircraft maintenance manual specifications and NAS1189 standards to ensure proper locking engagement.
