Product Features

1. Truss head self drilling screw is commonly used to attach cabinets to steel studs. They are also used in electronics items and in applications requiring low clearance above the head. Finally, steel truss head screws are used to assemble metal parts that will be used in humid environments.

2. Truss head screws have a wider head than their pan head counterparts. You can find them in different lengths. Nonetheless, most trust head screws have a wider head than pan head screws. Truss head screws also have a lower profile than pan head screws.

3. With their wide and rounded head, truss head screws offer several benefits. They are incredibly strong, for instance. Truss head screws are often used to assemble fuselages and other aerospace components because of their superior level of strength.

4. Another benefit of truss head screws is better load distribution. All truss head screws have a wide head. Along with a round shape, this is one of their defining characteristics. When installed, the wide head will distribute the load while subsequently protecting the part or parts from damage.

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.
