The most corrosion-resistant pan head slotted screws we offer. They have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads. With only two contact points, the slotted drive can't withstand much torque, so it's best to hand-tighten them.
Length is measured from under the head.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel can.
