Low-Profile Rounded Head Drilling Screws for Metal
Also known as pancake head screws, these have a head that is about two-thirds the height of standard rounded head screws. They're designed to attach framing to metal up to 3/16" thick. They save you time and effort by drilling their own holes and fastening in a single operation. Made from steel, they have a zinc plating to resist corrosion in wet environments. Length is measured from under the head.

Screws for Hardwood
Also known as Type 17 auger point screws, these penetrate hardwood and reduce driving torque. They require a pilot hole to prevent splitting when used near an edge. They're beveled under the head for use in countersunk holes. Ribs underneath the head prevent loosening. Made from 18-8 stainless steel, they have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. Screws may be mildly magnetic. Length is measured from the top of the head.

Square-Drive Small-Head Drilling Screws for Joining Drywall to Metal Framing
These screws have a drill point that powers through drywall and into metal studs up to 0.105" thick. Heads are one-third smaller than those of other drywall screws. Screws are black-phosphate steel to resist corrosion in dry environments. Length is measured from the top of the head.
