BZP Throughbolts – ETA Option 1
- Premium torque controlled expansion anchors
- ETA Option 1 – Approved for safety critical applications in cracked and uncracked concrete
- Versatile through fixing for multiple applications
These CE marked throughbolts have an Option 1 European Technical Approval making them suitable for safety critical applications in both cracked and non-cracked concrete.
Throughbolts achieve good loads and are quick and easy to install. They have the advantage of being through fixings with the drill size being the same diameter as the anchor . They are simply hammered into the hole and tightened to draw the cone into the expansion clip.
