Lightweight concrete screw HL-W, wafer head, Corrseal

ESSVE Lightweight concrete screw is used for anchoring in porous materials such as lightweight concrete, also known as Leca, Ytong, Siporex, blue concrete etc. The lightweight concrete screw can be used to install wooden studs and steel joists, sill installation, installing fittings securing insulation etc. For the installation insulation, for example, ESSVE Insulation holder’s Washer Ø90 mm, item number 36122, can be used.The screw is classified in corrosivity category C4, which means it is suitable for both outdoor and indoor use.

Lightweight concrete screw’s thread is designed for porous materials such as lightweight concrete. The screw has a large head diameter, which provides a very high clamping force to the base material.

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.
