    One-third the weight of steel, these are the lightest flanged screws we offer. They have an oversized flange that spreads pressure over a large area to protect thin material without needing a washer. 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.

    6061 AluminumWith a high strength-to-weight ratio, these lightweight screws offer good corrosion resistance.
