Product Description
The AN174H5A is a close-tolerance hex head bolt manufactured from alloy steel per NASM6812 specifications. The 'H' designation indicates a drilled head for safety wire installation, while the 'A' denotes an undrilled shank. This bolt is engineered for interference-fit structural joints where precise alignment and minimal shear movement are critical—such as wing attach fittings and high-stress connection points.
Installation requires matching the correct grip length to the application and securing with a self-locking nut or appropriate safetying method per aircraft IPC/SRM documentation. Close tolerances ensure reliable load transfer in primary structure.
