Slotted/Phillips Truss Combo Head Machine Screws
Zinc Plated Steel
Slotted Phillips Truss Combo Head Machine Screws are often used with nuts as well as driven into tapped holes. In practice, they tend to be mostly available in smaller sizes and the smaller sizes are referred to as screws, or less ambiguously as machine screws, although some kinds of machine screw can be referred to as stove bolts. They can be driven by either a slotted bit or flathead screwdriver and a phillips bit or phillips screwdriver.
Slotted Phillips Combo Head Machine Screws in Zinc Plated Steel add a layer of corrosion resistance to plain alloy steel. Clear zinc has a light, shiny color and blue zinc has a bright blue hue. Zinc plated steel is not suitable for extreme environment use, as it is not as resistant to corrosion as hot dipped galvanized.
