Hex washer head self drilling screws have a hex head designed to be driven by a wrench or socket. These screws tap their own holes using their self drilling (TEK) point to pierce through 20 to 14 gauge metals. Their threads also cut into the material for better retention, particularly in wood.

Product Features

1. Because of the inherent challenges in metal-to-metal fastening, hex washer head screws are designed with unique features that make them perfectly adept at fastening metal components to other metal components with strength and ease.

2. The larger screws are used in roofing and other industries which require self-drilling through tough metals. Our screws come in stainless steel, alloy steel, carbon steel and other materials which prevents corrosion.

3. With a lower installation torque, the threads on these screws allow for a quick transition from drilling to tapping. For effective penetration, make sure that at least three threads of the fastener are inside the material.

4. Many of our hex washer head self drilling screws have the washer built solidly into the screw itself, which allows the surface pressure to be more evently distributed across the surface of the screw for a more secure fit and stronger fastening.

Application

Self drilling screws are used primarily when fastening into steel or other metals and are typically used to join materials like sheet metal. These screws are identified by the unique point or flute at the end of each screw. Self Drillers are used to save time and effort, because they eliminate the need to drill a pilot hole, tap it, and then install the screw.
