Frequently Asked Questions (FAQs)

1. What are insert nuts used for?

The purpose of insert nuts is to create a stable and secure hold with the bolt. In certain objects, particularly those made of wood, bolts may gradually pull out over time. Insert nuts prevent this from happening by gripping into the object. The exterior threading will bite into the object during insertion.

2. Are insert nuts strong?

They offer a stronger alternative to weld nuts and tapped holes, and they provide a stronger bond than self-tapping screws. In fact, threaded inserts are usually the strongest and least time-consuming fasteners used in any manufacturing setting, especially because they were designed for automation.

3. How strong are threaded inserts?

Helical Thread Inserts They are vibration and impact resistant and will not strip or seize. All inserts are made from 18-8 stainless with a hardness of RC 43-50 and tensile strength above 200,000 psi.
