Key Insert – High-Strength Thread Reinforcement Solutions

We manufactures a complete range of Key Insert (Key Locking Inserts) designed for high-strength thread reinforcement, thread repair, and superior pull-out resistance in lightweight or soft materials.
Built with a solid-body construction and positive mechanical locking keys, these inserts ensure reliable performance even under extreme vibration and load conditions.

What is Key Insert?

Key-Locking Inserts are solid metal threaded inserts featuring:

• A rigid, single-piece body

• Precision internal threads

• Deep spiral external threads

• Two (or more) steel drive keys at the top

Once installed, these keys are driven into the parent material to create a permanent mechanical lock, preventing rotation and pull-out.
