The core-drilling innovation of EJOT Opticore

EJOT’s patented Opticore fastener was developed to improve the installation of membrane faced composite panels. Opticore drills, cores and fixes in one easy operation, whilst supporting thermal retention

The simplicity of Opticore is its moulded nylon head, engineered to create its coring action whilst eliminating the possibility of damage to the liner as the fastener pulls up.

This unique design also provides a dual bi-hex and internal driving option, creating fast and confident installation into hot rolled, cold rolled and timber substrate applications. Once in place, the plastic to metal relationship of the system provides significantly better thermal retention values.


The Opticore range comprises of fastener and stitcher in carbon and stainless steel finishes.
