Working with Jindai Fastener Manufacturer
Production Consistency
As a fastener manufacturer, we control cold heading, thread rolling, heat treatment and mechanical testing in one site. This keeps grade 8.8, 10.9 and 12.9 bolts consistent from batch to batch and shortens lead time for repeat orders.
Inspection and Export Support
Each batch is inspected before shipment, and test reports cover tensile strength, proof load, hardness and impact where required. For more detail, see our factory capability and quality control and test reports pages.
