Lightweight concrete screw HL-C, countersunk head, Corrseal

Lightweight concrete screw’s thread is designed for porous materials such as lightweight concrete. The countersunk screw is equipped with cutting grooves to minimise the risk of over-tightening and facilitate countersinking in the wood.

CE marking for ESSVE Lightweight concrete screw HL is based on ETA-20/0335.

The lightweight concrete screw is screwed directly into the lightweight concrete, i.e. no pre-drilling is required. A torque screwdriver is recommended for installation. Use a low speed on the screwdriver to avoid over-tightening the screw. Over-tightening can mean that the thread is stripped, which greatly reduces the load capacity and a new installation should be carried out.
