Steel Pan Head Phillips Screws with External-Tooth Lock Washer
 |
Sharp external teeth provide a stronger grip than internal-tooth lock washers during frequent vibration. These screws are less likely to come loose, but the teeth may snag on surrounding objects. Also known as Sems screws, the washer rotates freely but is permanently attached. These screws have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads. The Phillips drive easily aligns with drivers and withstands more torque than slotted drives, but drivers slip when you apply too much force.
Length is measured from under the head.

Stainless Steel Pan Head Phillips Screws with Internal-Tooth Lock Washer
 |
 |
These corrosion-resistant screws have a washer with sharp internal teeth to keep screws in place during vibration. Unlike external-tooth lock washers, their smooth outside edge provides a finished look and won’t snag on surrounding objects. Also known as Sems screws, the washer rotates freely but is permanently attached. These screws have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads. The Phillips drive easily aligns with drivers and withstands more torque than slotted drives, but drivers slip when you apply too much force.
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.
