Compare drilling, pointed, thread-forming, and thread-cutting tips to find the best choice for your material.
Steel Serrated-Flange Hex Head Drilling Screws
 |  |
Serrations on the flange grip material for a tighter, more vibration-resistant hold than other drilling screws. The flange also spreads the load to prevent crushing thin metal. Turn the hex head with a nutdriver or socket to drill and fasten in one step.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
Corrosion-Resistant-Coated Steel—The coating has been tested to extreme standards, including 1,000 hours of salt spray resistance, to hold up in wet and outdoor environments.
