BOLT THREADS, DAMAGED
Damaged threads decrease the load-bearing capability of bolts.
Damaged threads can be repaired or cleaned using
thread file or triangular shaped file.
The threads must be cleaned to remove any dirt or metal particles which might cause
further damage to threaded holes.
In the event that bolt threads are damaged beyond repair and proper bolts are not
available, refer to BDAR procedures (para 3-24) that address missing bolts.
Limitations:
Possible decrease in load-bearing capability.
