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.
