Description

The DK insert is a low profile, splined, bubbling insert in aluminum or steel construction offered in a wide variety of standard and metric thread sizes. Bubbling means that during the installation process, the insert collapses into a bubble shape on the backside of the application material. The application material is clamped between the flange of the insert and the bubble shape resulting in high resistance to pull-out loads. Because the insert forms a bubble on the backside of the application, the DK insert cannot be used in blind hole applications.

The bubble also serves as a load bearing surface, which absorbs the force of setting the insert. Otherwise the setting force, or clamp load, could spread into the application material and might damage the material. This makes the DK insert ideal for use in thin sheet, soft, brittle and low strength materials.

The splined body of the DK insert press into the application material during the installation process. Splined inserts are 50% less likely to turn in the application hole compared to plain body inserts. Splined inserts are ideal for soft materials such as aluminium, magnesium and plastics, where plain body inserts might otherwise fail. The splines also improve electrical continuity in sheet metal applications and electrical assemblies. The low profile flange of the DK insert results in near flush installation and clamp up making it ideal for flush fitting, thin sheet and low load bearing applications.

Features
