The EXPANSIONSERT 2 thread insert consists of a body with internal thread, which has knurls and undercuts on the circumferential surface.
Inside the body, there is an spreader plate that is pressed downwards when the thread insert is installed in the mounting hole. Upon installation, the slotted bottom part of the EXPANSIONSERT 2 is expanded and its cutting rings are anchored in the wall of the mounting hole. The thread insert is thus reliably secured against pull-out and twisting.
Advantages: • For reactive resins, PUR, elastomers, integral hard foams as well as for wood composite materials • Wear-resistant threads • Quick, cost-effective installation
