1/4 inch UNC Phillips Fillister Head Machine Screws ASME B18.6.3 in A2 Stainless Steel

UNC Phillips Fillister machine screws have a large cylindrical head, with a slightly convex top surface. Fillister head screws are the preferred head type for counterbored holes and can also be used for protecting a surface by raising the level by which the tool is used to tighten the fixing. They are similar to a Pan head machine screw, but with a greater head height. Height to diameter ratio is also larger than a cheese head. Imperial Unified Coarse thread version.
