Steel Round Head Combination Phillips/Slotted Screws
 |
With two common drive styles in a single screw, you'll always have a compatible driver on hand. A Phillips driver easily aligns with the cross-shaped opening on these screws, while a slotted driver works in a pinch. However, the combination drive won't handle as much torque as a dedicated Phillips drive can. The round head has a domed profile that gives a smooth, decorative look to brackets and architectural features.
Length is measured from under the head.
