Product Introduction

This anaerobic thread locker screw glue is a single-component anaerobic adhesive, which cures quickly in an oxygen-free environment between metal threads. It effectively locks, seals and fixes bolts, nuts and threaded fasteners. It can prevent loosening, shaking, rusting and oil leakage caused by long-term vibration, temperature change and mechanical operation. Suitable for automobile, motorcycle, machinery and hardware maintenance, it is an essential industrial and household thread fixing tool.

Core Features

Anaerobic Curing: Solidifies only on metal threaded gaps, no curing on the surface exposed to air, safe and efficient.

Anti-vibration & Anti-loose: Strong locking force, effectively prevent screw loosening caused by equipment vibration.

Excellent Oil Tolerance: Works normally on slightly oily thread surfaces, no need for extreme cleaning.

Anti-rust & Sealing: Fills thread gaps tightly to avoid air and water ingress, prevent rust and leakage.

High Temperature Resistance: Stable performance from -55℃ to 150℃, suitable for high-temperature working environments.

Three Strength Options: practical medium strength, permanent high strength for different needs.
