FAQ

What materials are compatible with these threaded inserts?

The inserts are designed for soft metals such as aluminum, cast iron, magnesium, and similar alloys. They work well in applications where the base material is not as hard as steel, providing a reinforced thread that can handle repeated fastening.

Do I need special tools to install the inserts?

No special tools are required. You can install the inserts using a standard drill to create the pilot hole, a tap to cut the internal thread, and a screwdriver or jam nut to turn the insert into place. An E-Z LOK drive tool can also be used for faster installation, but it is not mandatory.

How many inserts are included in the package?

Each package contains ten threaded inserts, giving you enough units for multiple repairs or for stocking in a workshop setting.

Can these inserts be used in high‑temperature environments?

While the carbon steel construction offers good strength, the inserts are not specifically rated for extreme high‑temperature applications. For such conditions, consider a heat‑treated or specialty alloy insert.

What is the warranty or return policy?

We offer a standard manufacturer warranty covering material defects. If you receive a defective product, contact our support team within 30 days for a replacement or refund.
