What Is Threadlocker Adhesive?

Threadlocker is a liquid adhesive applied to threaded fasteners before or after assembly. When placed between metal threads, the anaerobic adhesive cures in the absence of oxygen and creates a strong bond between the screw and nut threads.

Unlike traditional mechanical locking methods such as spring washers or nylon nuts, threadlocker provides full thread contact protection, reducing vibration loosening and improving sealing performance.

Typical applications include:

• Thread locking for bolts and screws

• Vibration resistance solutions

• Corrosion protection

• Thread sealing

• Component positioning

• Gap filling between threaded parts

Advantages of Threadlocker for Industrial Fastening Applications

1. Excellent Anti-Loosening Performance

One of the biggest challenges in industrial assembly is fastener loosening caused by vibration, shock loads, and temperature changes.

Thread locking adhesive for screws creates a strong chemical bond between mating threads, preventing unwanted movement during operation.

Benefits include:

• Improved joint reliability

• Reduced maintenance requirements

• Prevention of bolt back-out

• Increased equipment service life

This makes threadlockers ideal for:

• Automotive engines

• EV battery modules

• Railway equipment

• Industrial robots

• Heavy machinery

2. Superior Vibration Resistance

Mechanical equipment often operates under continuous vibration.

Traditional fastening methods may gradually lose preload force. Threadlocker fills the microscopic gaps between threads and maintains stable clamping force.

Typical applications:

Automotive Industry

Used for:

• Engine fasteners

• Transmission components

• Brake systems

• Suspension components

• EV structural parts

Robotics Industry

Used for:

• Servo motor assemblies

• Precision mechanical joints

• Robotic arms

Rail Transit

Used for:

• Bogie components

• Interior structures

• Mechanical equipment connections

How to Use Threadlocker Correctly?

Proper application is essential to achieve maximum locking performance.

Step 1: Cleaning Thread Surfaces

Before applying threadlocker:

• Remove oil

• Remove grease

• Remove dust and contamination

Use suitable cleaning agents to ensure the thread surface is dry and clean.

Step 2: Apply Primer When Required

For difficult materials such as:

• Stainless steel

• Aluminum alloy

• Magnesium alloy

a primer accelerator can improve curing speed and bonding performance.

Step 3: Apply Threadlocker

Apply several drops directly onto the screw thread engagement area.

Recommended application:

• Avoid excessive adhesive

• Ensure full thread coverage

• Select correct strength grade

Step 4: Assembly and Torque Control

Install the screw or bolt according to engineering specifications.

Correct torque control ensures:

• Proper preload

• Stable fastening performance

• Reduced assembly defects
