Manufacturing
Traceability with Lot ID
General - Traceability - Testing

Bolt, Nut and Washer Lot Traceability begins when the material arrives at the factory. Material is sample tested upon arrival to verify the Mill Certification.

Prior to the start of manufacturing, a traceable "ID CODE" is assigned for specific lots of material that will be used to produce the bolt, nut and washer assembly. Heat Code information is kept with the products throughout the manufacturing process.

At the start of manufacturing, the assigned "ID CODE" is stamped on the head of every SmartHex™ bolt. This code can then be traced back to the actual heat lot of material used for manufacturing.

When a heat lot of material is depleted, or different processing is used, the "ID CODE" is retired and a new "ID CODE" is established for the next production run.
