Product Description

Metric Zinc Plated Carbon Steel Kep Nuts K Lock Hex Nuts with External Tooth Lock Washer

Our Metric Zinc Plated Carbon Steel Kep Nuts, also known as K Lock Hex Nuts with External Tooth Lock Washer, are designed for secure and efficient fastening in industrial assembly, machinery repair, equipment maintenance, electrical equipment, automotive parts, and general hardware applications.

This product combines a standard hex nut with an external tooth lock washer. During tightening, the toothed washer helps improve grip on the contact surface and helps reduce loosening caused by vibration or repeated movement. Compared with using a separate nut and washer, Kep nuts help simplify installation and reduce the risk of missing washers during assembly.

Made from carbon steel and finished with zinc plating, these nuts provide a clean silver-blue appearance and practical surface protection for regular industrial fastening use.
