SS Oval Hd Phillips Machine Screws 1/4" - 20x2"

Sold in sets of 100 Countersunk designs consist primarily of flat, oval, and bugle heads. Unless the material is very soft, flat and oval heads require a countersunk hole. The advantage is that little or no part of the head protrudes above the surface of the material. Raised heads, sometimes known as oval-shaped heads, have an angle much like flat screws but have more of a dome-shaped head. You’ll also need to countersink these screws to accommodate the angle.
