Product Description
The 20-057-4-26 is a shear bolt designed to carry transverse loads through close-tolerance structural joints in aircraft airframes. Manufactured from corrosion-resistant steel per NAS specifications, this bolt transfers shear forces through its shank rather than relying on thread engagement. Commonly used in hinge-fitting assemblies and control surface attachments.
Installation requires a reamed hole with precise grip length matching and a corresponding nut, torqued per the aircraft maintenance manual. The close-tolerance fit ensures load distribution without lateral play, critical for maintaining structural integrity under flight loads.
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.
