More About Part Number 609491

These 4-40 x 1/2" Mil-Spec Machine Screws feature a Flat Head with a Phillips Drive and are made from 18-8 Stainless Steel. They feature a Black Oxide Finish, which provides mild corrosion resistance and a dark matte appearance and is commonly used in indoor or lightly protected applications. The Flat Head sits flush or countersunk with the material surface when fully installed, making it a strong choice for applications that require a smooth, low-profile finish. A Phillips drive features a cross-shaped recess designed for efficient installation with standard Phillips drivers and power tools.
