Spread out holding power and protect surfaces from damage. Unlike cup and cone tip screws, the flat tip on these distributes pressure evenly, reducing marring but not holding as tightly. They're a good choice for repositioning parts frequently on jigs, fixtures, and other applications where the tip presses against a flat surface. Made of alloy steel, these screws are strong enough to hold components without wearing down.
Black-Oxide Alloy Steel—These screws have a dark matte finish that offers minimal corrosion resistance, so they're best for dry environments.
