Reliable & Secure Hardware Retention
ProTek RC Thread Lock gives RC racers reliable options for securing metal-to-metal fasteners and preventing screws from loosening due to vibration during operation. Available in four colors—blue, purple, orange, and red—each formula offers a different balance of holding strength and serviceability to suit a variety of applications. Developed through months of testing by ProTek RC racers and engineers, these thread lockers feature an improved applicator tip, updated storage cap, and clearer label instructions. With options ranging from easy-to-remove everyday fastener security to maximum-strength retention, racers can choose the right formula for their maintenance needs.
Purple Thread Lock – Light Strength for Small Screws
The purple formula (PTK-1578) is designed for small fasteners, including screws commonly found on 1/24-scale RC vehicles, and applications requiring protection against light vibration. Its light-strength hold helps keep small screws from backing out without making future maintenance unnecessarily difficult. Purple Thread Lock can be removed with standard hand tools, making it ideal for small-scale builds and frequently serviced components.
