 Inspection items:

 Appearance
( Scratch, Rusting & Oxidation)
Plating(Thickness & Color) Material Short Feeding Poor Forming Deformation
Dimensions Bending angle Chamfer Punch Thread
Burrs Defective Upsiding Down Defective Staking Displacement Mechanical Property

Problems to be prevented in transportation & storing:
▲oxidization resulting from fingerprints
▲deformation from accidental fall-off
▲rusting & oxidization problem on sectional area after long-time storing.
