Thread locker is a one-component anaerobic adhesive used to secure threaded fasteners (bolts, nuts, screws) and prevent them from loosening due to vibration, shock, or thermal cycling.

How It Works

• Remains liquid in the presence of air

• Cures (hardens) when confined between metal threads and air is excluded

• Forms a tough polymer that fills gaps, locking threads in place and sealing them

Main Functions

• Prevents self-loosening from vibration

• Seals threads against leakage, corrosion, and rust

• Maintains consistent clamp load

• Replaces mechanical locking methods (washers, lock nuts)

Typical Applications

• Automotive & motorcycle assemblies

• Industrial machinery and equipment

• Electronics and electrical components

• Pumps, gearboxes, motors, and valves

Benefits Over Traditional Locking Methods

• More reliable than spring washers or lock nuts

• Reduces parts count and assembly complexity

• Improves durability and long-term performance

• Provides both locking and sealing in one product
