Threaded Insert

Product Details:

Wire Thread Inserts, commonly known as Helical Inserts or Heli-Coils, are precision-engineered fasteners used to reinforce or repair threaded holes. They are coiled stainless steel or phosphor bronze wire with a diamond-shaped cross-section that forms internal threads when installed in a tapped hole.

Key Features:

• Thread Reinforcement – Strengthens weaker materials like aluminum, magnesium, or plastic.
• Wear & Corrosion Resistance – Made from stainless steel, phosphor bronze, or special coatings for durability.
• High Strength & Load Distribution – Distributes stress evenly, preventing thread failure.
• Lightweight & Space-Saving – Ideal for applications where weight reduction is critical.

Common Applications:

1. Aerospace & Defense – Strengthens threaded holes in aircraft structures.
2. Automotive & Engines – Used in aluminum engine blocks and transmission housings.
3. Electronics & Medical Devices – Provides durable threads in precision equipment.
4. Industrial Machinery – Extends thread life in heavy-load applications.

Types of Wire Thread Inserts:

1. Free-Running Inserts – Standard inserts that provide a smooth internal thread.
2. Self-Locking Inserts – Features a locking mechanism to prevent loosening due to vibration.
3. Tanged Inserts – Have a small tang for installation, later removed if necessary.
4. Tangless Inserts – No tang, reducing risk of foreign object damage (FOD) in sensitive applications.

Installation Process:

1. Drill – Enlarge the hole to the recommended size.
2. Tap – Use a special tap to create insert-compatible threads.
3. Install Insert – Use an installation tool to thread the insert into place.
4. Remove Tang (if required) – Break off the tang if necessary for through-hole applications.

Product Details:

The Loksert solid heavy duty key locking insert utilizes locking keys which provide a positive which provide a positive mechanical lock into the threads of the surrounding base material. The resulting thread is resistant to rotation due to vibration and torsion. Loksert solid key locking inserts require no special drills or taps.(Heavy Duty).
