Blind
threaded inserts also known as blind threaded rivets, rivet nuts, blind
rivet nuts and threaded inserts are designed to provide strong threads
in thin panel sections. The reason they are called "blind" is because
they can be installed from one side of the panel. Access to both sides
is not required. That's why these fasteners are ideally suited for tubing,
extrusion and other similar types of applications.
There are two basic types:
standard and heavy duty. The standard types are used for most applications where
strong threads are required for blind applications. Most commonly known as "blind
threaded inserts", they are installed using a spin/spin technique and tooling.
A pneumatic tool is used to draw the fastener in, compressing the unthreaded
portion of the fastener wall. The bulge that is created presses against the
panel creating a clamping force which tightly grips the sheet. In addition to
high thread strength and torque-out, these fasteners have minimal inventory
requirements since each size can accommodate many grip ranges. The heavy duty
type, most commonly known as "rivet nuts" are designed for the most
demanding applications. They are installed from one side using a "spin/pull"
technique. A hydraulic/pneumatic tool is used to draw the fastener in, creating
the bulge and clamping force as described above.

The advantages of blind
threaded insert technology:
- Fast, easy installation
- Strong, permanent threads
in thin panels
- Blind, one-sided installation
- Installs anytime during
production. Even in painted panels or in the field or repair applications.
- Works in close-to-edge
applications.
- Attaches to panels of
any hardness.
