One of the most significant advantages of self-fastening bolts is their ability to provide a stronghold in environments where traditional bolts might loosen over time due to vibration or thermal expansion. Their locking mechanism ensures that once tightened, the bolt remains securely in place until intentionally removed. This feature makes them invaluable in safety-critical applications such as bridge construction and aircraft maintenance.

The installation process of an M12 chemical anchor involves drilling a hole into the substrate to the appropriate depth, then filling it with a specially formulated two-part resin. The anchor bolt is then inserted into the resin while it's still pliable, and as the resin cures, it forms a tight grip around the bolt, creating a robust connection. The curing time varies depending on the specific chemical composition of the resin, ambient temperature, and humidity.
