18-8 SS Hex Head Tek Screw With Washer
Hex head self drilling screws are fasteners that have a drill point which enables users to drill them directly into material without having to pre-drill a hole. EPDM washer under the head provides a consistent weather-tight seal. These fasteners are available in 18-8 stainless steel which is more corrosion resistant, but softer than 400 series stainless steels. Because these screws are made of of a softer, more corosion resistant stainless than standard 410 stainless tek screws, they are well suited for specialty applications such as cooling tower construction.
