CONSTRUCTION SCREW ET-T, CORRSEAL
-
ESSVE Construction Screw ET-T is designed for joining wooden joists such as Cross Laminated timber (CLT), glulam, LVL, and construction timber, both indoors and outdoors. It is a single-step installation making it highly efficient for timber assembly. Using three ET-T screws can replace one wood connector and 18 wood connector screws, significantly reducing assembly time. When installing outdoors, ensure the wood is dry and frost-free.
-
The screw is equipped with one fibre cut at the point which reduces the drive-in torque and minimises splitting. Manufactured of hardened carbon steel and C4 classified surface treatment Silver CorrSeal. The screw conforms to the CE requirement as per EN14592.

Use ESSVE's specific system bits for a safe installation. Fit the system bits without the a bit adapter directly in the chuck. Consequently, screw installation must take place at a constant torque without stopping.Use a strong power driver for the best installation. A power screwdriver with variable speed control is recommended when installing in hard woods.Recommended rpm: 250-800/min.
