Low-Profile Ultra-Wide Truss Head Slotted Screws
When head height is important, these screws fit into spaces where other wide head screws won't fit. Also known as shutter screws, their ultra-wide truss head distributes the load over a large area for excellent holding pressure.18-8 stainless steel screws are chemical resistant and may be mildly magnetic. All are passivated for added protection against oxidation and corrosion. Length is measured from under the head.
