Easy Installation & Long-Lasting Lock-In — Engineering-Grade Fastening Solution
In high-vibration and high-stress environments such as aerospace assemblies, automated production lines, and heavy machinery, threaded connections are often at risk of loosening or failure. TOPSCREW’s key-locking threaded inserts use mechanical keys that lock the insert to the base material, ensuring that the connection remains secure even under intense vibration, repeated disassembly, or dynamic loading.
Installation is straightforward — drill, tap, insert the threaded insert, then drive in the keys — with no need for chemical thread lockers or specialized tools.
Designed for strength and material versatility, these inserts offer reliable fastening solutions even in demanding structural applications.
Ideal for Industries
• Aerospace — structural components and composite assemblies
• Automation & manufacturing machinery — motion linkages and assembly platforms
• Automotive & transportation — suspension mounts and engine brackets
• Maritime & marine equipment — vibration-resistant and corrosion-protected structures
• Precision machinery & medical devices — durability and secure fastening
For applications where reliability is mission-critical, key-locking threaded inserts deliver long-lasting, vibration-resistant, and unshakeable connections.
