👉 A strike fluid, also known as a locking agent, is a specialized lubricant used in mechanical systems to prevent parts from moving or sticking when a tool is applied. It typically contains additives like polymers, resins, or silicones that create a strong, durable film on metal surfaces when pressure is applied. This film resists wear and friction, ensuring smooth operation and extending the life of the machinery. When the pressure is released, the fluid separates, allowing the parts to return to their normal non-striking state. This mechanism is crucial in various applications, including metalworking, machining, and manufacturing, where maintaining precise and consistent tool engagement is essential.
