The ProTek RC Purple Thread Lock is a low-strength thread-locking compound designed specifically for small metal fasteners and precision RC applications. Formulated to help prevent screws, nuts, and bolts from loosening due to light vibration, this purple formula provides reliable holding power while allowing easy removal with standard hand tools.
Ideal for smaller RC vehicles, including 1/24 scale models, ProTek RC Purple Thread Lock is an excellent choice for delicate threaded connections that require secure fastening without excessive holding strength. Its removable formula makes it particularly useful for components that require frequent maintenance, adjustments, or disassembly.

(1) ProTek RC Purple Low-Strength Thread Lock (0.5 fl. oz.)
Apply a small amount of thread lock to clean metal threads before assembling and tightening the fastener. Allow approximately 24 hours for a full cure before subjecting the connection to operating conditions.
Note: Intended for metal-to-metal threaded connections. Avoid direct contact with plastic components, as thread-locking compounds may damage certain plastics. This low-strength formula is designed for smaller fasteners and should not be used where high-strength or permanent thread retention is required. Follow the manufacturer's instructions and safety precautions during use.
