One damaged bolt found – source of damage
unknown
Whitesell u.lized the customer’s on-‐line system to respond.
One bolt found with damage. Concern:
Unknown. Source of Damage:
The en.re produc.on process from cold-‐heading to threading to outside processing (heat treat and pla.ng) to op.c sor.ng to packaging was reviewed for poten.al root causes.
No obvious cause found.
However, Whitesell took steps to ensure it would not happen during any of the processes:
Internal:
Poten.al catch points in the threading process were iden.fied and consequently eliminated.
Work guidelines, control plans, and process FMEAs were updated to include addi.onal inspec.on points.
External:
Outside processes were reviewed with the process owner and sources of poten.al damage were eliminated.
Dozens of man hours in-‐house / two outside processors audited all because of 1 bolt that may have been damaged in transit to the customer.
