Sharp-Point Self-Tapping Screws for Thin Metal Sheets, Ductwork and Trim

Product Information

Sheet Metal Screws join compatible thin metal sheets and secure metal trim, corner angles and ventilation duct components where the assembly specification permits screw fixing. This range focuses on sharp-point self-tapping screws with spaced threads. A common head option is the hex washer head, which combines an external hex drive with an integral bearing flange. Confirm the head style and drive against the selected sample; an integral metal washer head is not a sealing gasket.

Self-tapping describes a screw that forms or cuts its mating thread in a suitable prepared hole. A sharp point is not the same as a drill point. For this range, prepare a drilled or punched pilot hole sized for the exact screw, sheet material and thickness, unless the selected fastener is specifically approved for self-piercing in that material. Self-drilling screws with fluted drill points are a separate specification. Select diameter, length and point type for the total sheet stack and required thread engagement, and confirm suitability by the fastener data and representative assembly testing.

Use a Drill/Driver with a correctly fitting nut driver for an external hex head, or a matching screwdriver or bit for a recessed-drive variant. Align and support the sheets, keep the tool square, and use controlled torque to seat the head without stripping the thin sheet or deforming the joint. Specify material and finish to match the metals being joined and the service environment; ordinary zinc plating is not a universal exterior or marine protection specification. Duct sealing, fixing spacing and restrictions on projecting screw points must follow the relevant duct or equipment instructions. This generic range does not carry an assumed structural load rating.
