Key Features Premium grade Formulated for metal to metal Disassembles with heat Prevents loosening due to vibration Resistant to petrol and oil etc High-Strength Permanent Vibratio n 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 ApplicationsHeavy-Duty RC & MotorsportsZ-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 EquipmentFrom 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 SealPrecision 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 250°C) using a soldering iron or small torch to soften the adhesive before unscrewing.Technical Specifications Type : High Strength (Red) Anaerobic Compatibility : Metal-to-Metal fasteners only Removability : Permanent (Requires heat for removal) Best For : Engine firewalls, drivetrain studs, and high-vibration structural bolts Show more
