Expansion inserts are two piece units consisting of a threaded insert and a captivated spreader plate.

When the spreader plate is depressed, the knurled portion of the insert expands and anchors the insert in the hole.

Standard Expansion Insert

The Standard Insert is used widely to provide strong brass threads in plastic parts of all types after molding. In addition to their use for conventional assembly techniques, standard inserts can also be installed to protrude, serving the dual purpose as an assembly-locating device. Highly versatile, standard inserts provide the answers ,or the majority of applications where long-life threads are required in plastic parts.

• Versatile - can be used in any type of plastic
• Simple press-in installation

Flange Expansion Insert

The Flange Insert features a flange with a large surface for effective electrical contact in addition to all of the design features of the standard insert. The flange may also be used to hold down mating parts. When used to permanently attach separate parts, the flange insert is placed through a hole in one part and into the cored hole in the parent material. When the insert is installed, it permanently affixes the added part. The insert is especially well suited for thin-section applications, since the downward force of installation is absorbed by the flange.

• Same superior design characteristics as Standard Inserts
• Simple installation tooling

Clinch Expansion Insert

The Clinch Insert, in addition to having all the features of the standard insert, features a pilot and a flange. The pilot may be clinched over a terminal, eyelet fashion, while the flange offers a broad surface for good electrical contact. Since the downward force of installation is absorbed by the flange, the clinch insert may be used in relatively thin sectioned applications. This insert is used extensively in the electric and electronic industries.
