Tapping Screws

Tapping screws that are designed to be used in wood or light gauge metal in a pre-drilled hole.

Screws can be used as replacements for nails or screws that have loosened from wood or steel.

3/8 HWH with EPDM bonded sealing washer provides maximum pullover strength in high wind uplift applications.

EPDM rubber is vulcanized to a steel washer to form an excellent seal & will cover any existing hole to prevent leaks from re-occurring.

Screws are available in both carbon steel with zinc plating or 304 Stainless Steel.
