Z-42 Thread Locker (Blue)

Professional Strength Vibration Protection for Metal Fasteners

Z-42 Thread Locker is a premium-grade "Blue" anaerobic adhesive designed to prevent the loosening of metal nuts, bolts, and screws. It is the ultimate insurance policy for any mechanical assembly, ensuring that fasteners stay securely in place even when subjected to extreme vibration, thermal expansion, and mechanical shock.

Why Engineers & Hobbyists Choose Z-42:

• Vibration-Proof: Specifically formulated to lock set screws, axle nuts, and engine mounts that would otherwise vibrate loose.
• Removable Strength: Provides a medium-strength bond that holds securely but allows for disassembly with standard hand tools.
• Versatile Protection: Not just for hobbies; it is equally effective on cars, motorcycles, bicycles, lawn equipment, and power tools.

Targeted Applications

RC Aeroplanes, Helicopters & Cars

A "must-have" for every flight box and pit bag. Use Z-42 on engine mounting screws, rotor head assemblies, and drivetrain components. It is essential for any metal-to-metal contact point on RC helicopters and nitro-powered vehicles where high-frequency vibration is constant.

Automotive & Workshop

From bicycle brake callipers to lawnmower deck bolts, Z-42 keeps your equipment safe and operational. It seals threads against leakage and prevents corrosion, making future maintenance easier while ensuring current layout integrity.

Pro-Tips for a Secure Lock

• Precision Application: A little goes a long way. Apply a single small drop directly to the threads before assembly. For micro-fasteners, use Zap Flexi-Tips or Z-Ends for pinpoint accuracy.
• Clean Threads: For the strongest possible bond, ensure metal threads are free from oil, grease, or dirt before applying the locker.
• Removing Stubborn Screws: If a fastener is difficult to remove after the Z-42 has hardened, simply apply localised heat using a soldering iron or small torch to soften the adhesive, then unscrew as normal.
