A bolt with a single raised dash on its head is classified as what type?

A bolt with a single raised dash on its head is classified as an AN corrosion-resistant steel bolt. This designation indicates that the bolt is made from corrosion-resistant steel, specifically aligned with military and aerospace standards. The single dash is a key identifying feature that signifies the specific material type, which is crucial in ensuring the structural integrity and durability of the components in aviation applications.

In aerospace and aviation maintenance, understanding bolt classifications is essential, as they relate to the strength, corrosion resistance, and suitability for specific environments or applications. Corrosion-resistant steel bolts are preferred in areas where exposure to harsh conditions is likely, making them integral to ensuring safety and resilience in aircraft structures.
