Electric motor terminal screws are critical for safety and efficiency. They must endure continuous, high-frequency motor vibration and ensure a gas-tight, high-conductivity electrical connection. A loose terminal screw can lead to dangerous arcing, heat generation, power loss, and potential motor failure. However, these fasteners must be easily accessible for wiring changes, testing, or troubleshooting.
Don’t risk dangerous power loss or thermal damage; secure the connection while maintaining service access.
INCURE Re-Lok™ B22 Purple Light Duty Threadlocking Adhesive
For securing small, electrically-critical fasteners like motor terminals, where vibration security is needed but easy access is mandatory, low strength is the perfect balance. The INCURE Re-Lok™ B22 Purple provides a secure, anti-vibration lock designed for small threads, ensuring maximum conductivity and easy removal.
| Feature & Benefit | Technical Insight for Terminal Screws | Conversion Value |
| Low Strength (Light Duty) | Provides enough thread lock to prevent vibration-induced loosening for fasteners up to M6, allowing for easy removalwith basic hand tools. | Serviceability Guaranteed: Secure the wiring without fear of stripping threads during routine electrical maintenance. |
| Small Fastener Focus | Ideal for the low torque requirements of electrical lugs and terminal blocks, preventing over-torquing and damage to soft conductors. | Contact Integrity: Designed for small fasteners where precise, controlled clamping is paramount. |
| Corrosion Protection | The cured adhesive acts as a sealant, blocking moisture and atmospheric contamination from the threads, helping to preserve the connection’s electrical conductivity. | Prevent Oxidation: Maintain a clean, high-efficiency connection for the long term. |
| Vibration Security | Cures inside the thread gap, blocking all movement caused by high-frequency motor vibration, which is the primary cause of electrical connection failure. | Stop the Arc: Ensure the lug remains tightly clamped to the terminal, eliminating heat-generating movement. |
Application Steps: Securing Electric Motor Terminal Screws for Reliability
Preparation (Essential): Clean the threads of both the screws and the receiving terminal block thoroughly. Remove all existing oxidation, dirt, and wire residue. Ensure surfaces are perfectly dry before application.
Application: Apply a single, small drop of Re-Lok™ B22 Purple to the middle threads of the terminal screw. Only a minimal amount is required for effective light-duty locking. Ensure the product does not contact the conductive surfaces of the terminal or lug.
Assembly: Install the wiring lug and screw. Torque the fastener lightly to the manufacturer’s specified value. Proper torque is essential for the electrical connection.
Curing Time (Practical): While the initial cure is fast (around 20 minutes), allowing a few hours will help ensure the chemical lock is fully effective against continuous motor vibration before the motor is heavily used.
Stop risking dangerous electrical failures and secure your critical power connections with chemical certainty.
