#4-40 Phillips Flat Head Machine Screws in Black Oxide 18-8 Stainless Steel featuring a 100-degree countersunk head are often used for shorter length fasteners to allow for a greater threaded length.

Machine Screws of this style are very similar to a standard Phillips Flat Head Machine Screw, however the countersink underneath the head is shorter in length due to the angle of the taper. Because of this, 100-degree taper screws are often used when fastening thinner materials.
