Drilling Screws for Joining Drywall to Metal Framing
Power through drywall and into metal studs up to 0.105" thick. The curved neck sinks into drywall without tearing its paper surface. Length is measured from the top of the head.
Black-phosphate steel screws resist corrosion in dry environments.
Zinc-plated steel screws resist corrosion in wet environments.

Strip-Resistant Drilling Screws for Joining Drywall to Metal Framing
Ribs under the head act as a brake to prevent over-tightening and damaging threads. A drill point powers through drywall and into metal studs up to 0.105" thick. These screws are made from steel and have a zinc-aluminum coating that resists up to 500 hours of salt spray. Length is measured from the top of the head.

Drilling Screws for Metal Framing
A drill point powers through metal up to 0.105" thick. These screws are often used to fasten metal studs to metal floor and ceiling tracks in preparation for hanging drywall. They're black-phosphate steel to resist corrosion in dry environments. Length is measured from under the head.
