Coburn-Myers is proud to offer stover lock nuts, a proven and reliable fastener designed for use in high-vibration and high-stress environments. Also known as prevailing torque lock nuts, stover lock nuts are a top choice for industries such as automotive, aerospace, construction, and heavy machinery due to their ability to maintain secure fastenings under dynamic conditions.

What are Stover Lock Nuts?

Stover lock nuts are specially designed fasteners with a deformed, oblong top section that creates friction between the nut and the bolt threads when tightened. This frictional resistance ensures that the nut remains securely in place, even when subjected to vibration, shock, or high torque.

Unlike other lock nuts that rely on inserts, such as nylon lock nuts, stover lock nuts are made entirely of metal. Their all-metal construction makes them durable and resistant to extreme temperatures and harsh environments, adding reliability in critical applications.

How Stover Lock Nuts are Used

Stover lock nuts are commonly used in environments where components are subject to frequent vibration, movement, or stress. This includes:

• Automotive assemblies: In suspension systems, engine components, and other areas where vehicle parts experience constant movement.
• Heavy machinery: Industrial equipment exposed to dynamic loads and vibrations, where securing components is crucial for safety and performance.
• Construction and agricultural equipment: Machines that operate in demanding conditions require secure fasteners that resist loosening under stress.
• Aerospace and defense applications: In aircraft, where safety is paramount, stover lock nuts are used to secure vital components.

Steps for Using Stover Lock Nuts

1. Positioning: Stover lock nuts are installed by placing them onto the bolt after aligning the parts to be fastened. The deformed, or locking, end of the nut should face upwards, away from the surface being fastened.

2. Tightening: Using a wrench or appropriate tool, the nut is tightened onto the bolt. As the nut is tightened, the deformed section creates resistance as it engages the bolt threads. This resistance ensures that the nut will stay in place, even under vibration or high-torque conditions.

3. Non-reusable: Stover lock nuts are typically single-use. Once they are removed, the deformed section may lose some of its effectiveness, so it is recommended to replace them rather than reuse them to ensure secure fastening.

The Benefits of Stover Lock Nuts

• Vibration resistance: Thanks to the friction created by the deformed top, stover lock nuts are ideal for preventing loosening in high-vibration environments.
• No inserts required: Unlike nylon lock nuts, stover lock nuts do not rely on plastic inserts, which can degrade under high temperatures or harsh environments. This makes them suitable for a wider range of applications.
• Durability: Made entirely of metal, stover lock nuts offer superior durability and can withstand extreme conditions, including temperature fluctuations, high torque, and heavy loads.
