Fastener Locknut 5/8-11

Fastener Locknut 5/8-11

This is a 5/8"-11 Grade C top lock nut, a type of all-metal, prevailing-torque fastener used extensively on concrete mixer trucks. Its design features a distorted thread in the top section that creates a strong locking action, preventing the nut from backing off when subjected to the constant vibration inherent in mixer operations. This makes it a critical component for securely mounting various parts on Terex, Con-Tech, and other mixer brands, ensuring operational safety and reliability. The all-metal construction allows it to be used in higher temperature areas where a nylon insert nut would fail.

Key Features

• Grade C strength for heavy-duty applications.
• All-metal, prevailing torque design resists loosening from vibration.
• 5/8"-11 UNC coarse thread size.
• Zinc plated finish for corrosion resistance.
• One-piece design is reusable and suitable for high-temperature environments.
