Product Overview

The key-locking threaded insert is a thread insert locked by keys: after it is fitted into a light alloy or soft substrate, keys lock the insert body in place and prevent it from turning out with the bolt. Its torque-out resistance is markedly higher than that of ordinary thread inserts, making it suitable where high-strength internal threads are needed in low-strength materials such as aluminium and magnesium alloys or cast iron.

Technical Features

• Pin-locking structure resists torque-out and lowers the risk of being pulled out with the bolt.
• High-strength internal threads for soft substrates such as aluminium-magnesium alloy
• Carbon steel / stainless steel options to suit different corrosion-resistance requirements.
• Thread accuracy stays stable after installation, allowing repeated bolt removal.
• Length, thread diameter and mounting dimensions customisable to drawing
