Dorman 962-028 Prevailing Torque Lock Nut M8-1.25 Class 10.9 Metric

The Dorman 962-028 is a high-strength prevailing torque lock nut designed for critical fastening applications where vibration resistance is essential. This metric lock nut features an M8-1.25 thread specification and Class 10.9 strength rating, making it suitable for automotive, industrial, and mechanical assemblies.

Key Features:

• Prevailing torque design provides superior resistance to loosening from vibration and dynamic loads
• Class 10.9 strength rating offers high tensile strength for demanding applications
• M8-1.25 metric thread specification ensures proper fit with corresponding bolts and studs
• Engineered to meet or exceed OEM specifications for reliable performance
• Durable construction for long-lasting service life

This lock nut utilizes a prevailing torque mechanism that creates continuous friction between the nut and bolt threads, preventing loosening without requiring additional lock washers or thread-locking compounds. The Class 10.9 designation indicates a minimum tensile strength of 1040 MPa, making this fastener appropriate for high-stress automotive and mechanical applications where component security is critical.
