AN3-7A Bolt Aircraft Hex Head Intelligence

About

The AN3-7A is a precision-engineered aircraft hex head bolt manufactured to stringent aerospace specifications. This component features a 3/16-inch diameter with 7A thread configuration, crafted from high-strength steel or aluminum alloy depending on application requirements. The bolt undergoes rigorous heat treatment and surface finishing processes to meet AN (Army-Navy) standards for aviation hardware. Primary uses include structural assembly in aircraft frames, wing attachments, and control surface mounting where reliable fastening under extreme stress is critical. Key properties include exceptional tensile strength, corrosion resistance, and precise dimensional tolerances. The hex head design enables efficient installation with standard tools while providing superior grip compared to slotted alternatives. Makers and aerospace manufacturers source these bolts for experimental aircraft builds, restoration projects, and certified aircraft maintenance. The component's standardized specifications ensure interchangeability across different aircraft models, making it essential inventory for aviation workshops, maintenance facilities, and hobbyist builders requiring certified aerospace-grade fastening solutions.
