    Frequently Asked Questions

    What materials are wire thread inserts made of?

    Most wire thread inserts are manufactured from high-quality 304 or 316 stainless steel for superior strength, elasticity, and corrosion resistance. Some specialty kits may feature inserts made of copper alloy or surface-treated carbon steel.

    What is the difference between free-running and screw-lock inserts?

    Free-running inserts provide standard smooth thread insertion, while screw-lock inserts feature a unique tapered section in the middle that grips the bolt securely, preventing it from backing out or loosening due to heavy vibration.

    How does the installation tool work?

    The installation tool features a handle and a guide rod. You place the wire thread insert onto the guide rod and rotate it clockwise to drive the insert smoothly into the pre-tapped hole.

    Can damaged wire thread inserts be removed?

    Yes, they can be removed using the specialized removal tool included in the kit. The tool features reverse threads that hook into the insert's mounting handle, allowing safe extraction by rotating counterclockwise.

    What sizes do these thread repair kits usually cover?

    Kits are typically organized around standard size ranges (such as M4 to M8) and contain a variety of corresponding insert lengths to fit different application depths.
