MATERIAL: Case Hardened Steel

Product Description

The HK Series works on the pull/expand principle. The plug consists of an expandable sleeve around a mandrel type expanding element. By applying an axial force to the mandrel, while restraining the sleeve with a special tool, the sleeve is forced to radially expand and the sleeve anchors in the bore of the base material due to the roughness of the hole. Upon reaching a predetermined force,the mandrel brakes off and the plug is set.

One piece construction, ideal for automated high production requirements.
