Inspection should match the application

A useful inspection report is not simply a thick document. It should cover the buyer risk. Standard parts, distributor stock, repair replacement, and high-accuracy projects focus on different inspection points.

Common inspection points

Common points include appearance, diameter, lead, overall length, thread length, end dimensions, runout, nut running condition, and packing condition. Demanding projects may need clearer accuracy or preload confirmation.

Photos are also quality records

For export orders, product photos, label photos, packing photos, and key dimension photos before shipment reduce receiving disputes. Distributors especially need these records for local customer confirmation.

  • State which inspection points are needed.
  • Confirm whether dimension photos or data are required.
  • Describe accuracy grade, preload, or backlash requirement.
  • Ask for product, label, and packing photos before shipment.
