Z-71 Thread Locker (Red)

High-Strength Permanent Vibration Protection

Z-71 Thread Locker is a high-strength "Red" anaerobic adhesive designed for heavy-duty applications where a permanent bond is required. It is engineered to lock metal-to-metal threads securely, ensuring that critical fasteners remain in place even under the most extreme conditions of vibration, heat, and mechanical stress. Once cured, it creates a bond that resists loosening even in high-torque environments.

Why Engineers & High-Performance Hobbyists Choose Z-71:

• Permanent Hold: Formulated for fasteners that are not intended for frequent disassembly.
• Maximum Vibration Resistance: The ultimate choice for engine mounts, drivetrain components, and structural metal frames.
• Broad Application: Ideal for RC aeroplanes, helicopters, cars, and boats, as well as automotive, industrial, and garden machinery.

Targeted Applications

Heavy-Duty RC & Motorsports

Z-71 is the go-to for high-stress areas like petrol engine firewalls, motor mounts in large-scale RC cars, and main rotor shafts in high-performance helicopters. It provides peace of mind for any metal fastener that must never vibrate loose during operation.

Workshop & Outdoor Equipment

From heavy-duty lawnmower blades to automotive suspension components and snowmobile assemblies, Z-71 helps maintain the total integrity of equipment subjected to relentless pounding and environmental exposure.

Pro-Tips for a Permanent Seal

• Precision Control: Use only a small amount; a single drop on the threads is sufficient for most fasteners. For ultra-fine threads, use Zap Flexi-Tips or Z-Ends to avoid excess mess.
• Clean Bonding: Ensure all threads are degreased and dry before application to ensure the anaerobic reaction reaches maximum strength.
• Disassembly Requirements: Unlike the Blue Z-42, Z-71 is a permanent locker. To remove a fastener, you must apply localised heat (approximately 250C) using a soldering iron or small torch to soften the adhesive before unscrewing.
