Truss Head Self Drilling Screw are commonly used to attach cabinets to steel studs. They are also used in applications requiring low clearance above the head. Finally, Truss Head Tek Screw are used to assemble metal parts that will be used in humid environments.
In addition to securely holding thin materials, Truss Head Tek Self Drilling Screw are frequently chosen for fastening sheet metal and other material types that have large holes. The wide head of the screw works to cover holes that are larger than the body of the screw for an attractive finish. The dome shape of the heads of truss Screws is low enough to use for most projects, but an advantage is that the screws are difficult to remove or tamper with. Another advantage of a truss screw is that the wide head prevents it from sinking too deeply into the material and causing tearing.
