One screw for every base material
HEA Tapper is a universal direct-threading concrete screw — it cuts its own thread into concrete, block and brick, with no plug and no chemical.
The coating: Blue Ruspert — a multi-layer coating that withstands 1,000 hours in the salt spray chamber. For comparison: standard cold galvanizing lasts only 96–200 hours.
Frequently asked questions
What is the difference between HEA and TFE?
TFE is a structural concrete screw with ETA approvals — for cracked concrete, seismic and fire applications. HEA is a universal screw for general anchoring that also works in block and brick, with an especially durable coating.
What is Blue Ruspert coating?
A multi-layer coating (zinc + organic layers) that withstands 1,000 hours in the salt spray chamber — 5 to 10 times more than standard cold galvanizing. Suitable for outdoor use and humid environments.
