MS20253P5-7200 Piano Hinge Pin is an aerospace hinge component designed to provide a durable pivoting connection within aircraft hinge assemblies. Supplied in a 6 ft length, this hinge pin is used with compatible hinge segments to allow smooth rotational movement while maintaining structural alignment and load capability in aircraft applications.

Manufactured to the MS20253 specification, this hinge pin features a corrosion-resistant steel construction with a cadmium-plated finish for improved protection against environmental exposure. The precision-formed pin provides reliable retention through hinge assemblies while supporting repeated movement and operational loading.

The MS20253P5-7200 is commonly used in aircraft piano hinge installations, including access panels, inspection doors, fairings, control surfaces, and removable aircraft structures where continuous hinge operation and secure mechanical retention are required. The long-length configuration allows cutting to the required application length during approved maintenance or manufacturing procedures.

During inspection and maintenance, the hinge pin should be checked for corrosion, bending, wear, deformation, and proper engagement with the hinge assembly. Replacement of damaged or worn hinge pins helps maintain correct alignment, smooth operation, and continued airworthiness of the aircraft structure.
