Stainless steel screw 4 x 50mm

Wood screws are the fastener for marine environments that resists corrosion.

The unique geometry of the SCI A4 | AISI316 wood screws features a self-perforating tip with a setback notch, a particular asymmetric “umbrella” thread, an elongated cutter, and sharp under-head ribs.

Geometric details provide the screw with greater torsional strength for more secure screwing. The A4 | AISI316 austenitic stainless steel ensures excellent corrosion resistance, which is ideal for applications in seaside environments.

The wood screw is suitable for use without pre-drilling on timber boards with a density of up to 470 kg/m3 and with pre-drilling on timber boards with a maximum density of 620 kg/m3.
