Concrete screw

Hexagon head

• Hexagon head ensures improved application of force when screwing in for fast and easy processing


• Standard open-end or box-end wrenches are sufficient for processing


• Pressed-on washer with locking teeth


• Greater user safety and faster processing due to more secure connection from engagement in the material

Self-tapping double thread

• Robust, form-fitting material connection ensures user safety


• Higher pull-out values in comparison to concrete screws without double thread

Complete concrete screw

• Shorter processing times when using in-place installation


• Can be loaded immediately after installation


• Combines high working loads with low axial spacing and edge distances (high pull-out values), which provides greater user safety


• Can be completely removed quickly and easily

Fire resistance

• Fire resistance R30, R60, R90 and R120 for M8-M16: Technical report TR020 "Evaluation of anchorages in concrete concerning resistance to fire" (included in ETA-11/0336)
