Make the specification comparable

For fasteners, brackets, fittings and machined components, details such as material grade, thread, tolerance and finish can change both price and supplier suitability. Identify the drawing revision and distinguish mandatory requirements from preferences.

What to include in a component request

  • Drawings or samples, dimensions and critical tolerances.
  • Material grade, coating or other surface treatment.
  • Quantities by part, packaging and delivery schedule.
  • Inspection methods and any material or test records required.

Clarify production and inspection capability

Ask which processes the supplier performs and which are subcontracted. Discuss how critical characteristics will be checked and recorded. A general factory description does not establish capability for every material, finish or precision requirement.

Approve samples before scaling the order

Record sample findings and any changes needed for production. For a repeat order, confirm that the same specifications and acceptance criteria remain in force. Supplier process changes, substitutions and drawing revisions should be reviewed rather than assumed equivalent.

Keep mixed orders identifiable

Small components can be difficult to distinguish during receiving and consolidation. Agree part labels, quantities per package and a packing list that connects each carton to the purchase order. This supports warehouse checks and helps resolve discrepancies before shipment.
