With nearly twice the tensile strength of others, these alloy screws are the strongest flanged rounded head screws we offer. The flange spreads out pressure, reducing damage to thin and soft materials. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver.
Length is measured from under the head.
Black-Oxide Alloy Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
