ROTHOBLAAS COUNTERSUNK INVISIBLE HEAD SCREW

Wood screws KKT A4 | AISI316 – ideal fastener for terraces and facades.

KKT A4 | AISI316 wood screw is designed for very aggressive environments and chemically treated wood.

Inverted (left-handed) thread under the head guarantees excellent pulling power; small-size tapered head provides excellent concealment in wood.

The triangular-shaped threads allow the wood fibers to be cut through during screwing, guaranteeing exceptional penetration ability deep into the wood.
