Fastener Locknut - 3/4"-10

Fastener Locknut - 3/4"-10

The 3/4"-10 Unitorque Locknut is an all-metal, prevailing-torque hex nut featuring a distorted top thread section that creates a secure locking action. Unlike standard nylon-insert locknuts, this all-metal design can withstand high temperatures, chemical exposure, and extreme dynamic loads without losing its holding power. It is widely used across general concrete mixer equipment for securing critical structural components, drivelines, and heavy-duty brackets. The cone-shaped top allows for proper orientation during assembly, while the flat bottom provides a solid bearing surface for reliable joint integrity.

Key Features

• All-metal prevailing torque design resists loosening from severe vibration and shock
• Distorted top threads provide a mechanical lock without the need for nylon inserts or lock washers
• Withstands high-temperature and chemically harsh environments better than standard Nyloc nuts
• Cone-shaped top ensures proper orientation during installation
