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.
Red Thread Lock – Maximum Strength for Critical Fasteners
The red formula (PTK-1580) delivers maximum holding strength for critical metal-to-metal connections where a loose screw could cause significant mechanical problems. It is suited to demanding, high-heat applications such as engine mounts, where fastener security is especially important. Removal is difficult and requires direct heat applied to the fastener at approximately 500°F, so red is best reserved for applications where maximum retention takes priority over convenient disassembly.
