Metric Heavy Duty Industrial Style Keylocking Inserts are a practical solution for addressing stripped, damaged, or worn-out threads in various applications. Whether it’s repairing threads or reinforcing them in original equipment, these inserts play a crucial role. Especially useful in soft metals like magnesium or aluminum, where threads may be prone to damage, they provide added strength and durability.
What sets these inserts apart is their ease of installation and removal. Unlike some alternatives that require specialty tools like drills, taps, or pre-winders, these inserts simplify the process. The keys, driven down into the surrounding base material, securely lock the insert in place, ensuring reliability and stability.
