Steel Slotted Flat Head Screws for Wood
These steel screws are zinc plated to resist corrosion in wet environments. All are beveled under the head for use in countersunk holes. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Length is measured from the top of the head.

Brass Slotted Flat Head Screws for Wood
Brass screws are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. All are beveled under the head for use in countersunk holes. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Length is measured from the top of the head.

Stainless Steel Slotted Flat Head Screws for Wood
18-8 stainless steel screws have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. All are beveled under the head for use in countersunk holes. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. They may be mildly magnetic. Length is measured from the top of the head.

Stainless Steel Slotted Oval Head Screws for Wood
18-8 stainless steel screws have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. A decorative rounded top provides a finished appearance. Screws are beveled under the head for use in countersunk holes. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw. Screws may be mildly magnetic. Length is measured from the edge of the head.

Stainless Steel Slotted Decorative Rounded Head Screws for Wood
18-8 stainless steel screws have good chemical resistance and are a good choice for ACQ-treated (arsenic-free) lumber. A decorative rounded top provides a finished appearance. They press threads into material for a tight, secure hold. To prevent splitting, drill a pilot hole slightly smaller than the screw.They may be mildly magnetic. Length is measured from under the head.

Screw Assortments for Wood
Flat Head
Rounded Head
For rounded-head screws, length is measured from under the head. For flat-head screws, length is measured from the top of the head.
Zinc-plated steel screws are corrosion resistant in wet environments.
18-8 stainless steel screws are chemical resistant and may be mildly magnetic.
