#10-16 x 1/2 IN Hex Head Slotted Self-Tapping Screw - Zinc Plated Alloy Steel
While other screws and bolts require holes with threads, tapping screws create their own threads. They have a pointed end to penetrate thin material such as sheet metal, and soft material such as wood and drywall. These steel screws are zinc plated to resist corrosion in wet environments. All have a hex head for a secure grip with a wrench and a flange to reduce the risk of crushing thin metal.
