Secure thin and soft materials in corrosive environments without needing a separate washer. A flange on these screws spreads pressure evenly over a wide area. Made of stainless steel, they won't rust, but they're not as strong as alloy steel. 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.
Head height includes the flange. Length is measured from under the flange.
Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these screws won't degrade when exposed to harsh weather, salt water, and most chemicals.
