18-8 Stainless Steel Socket Head Screws
Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Length is measured from under the head.Chrome-plated stainless steel screws have a decorative, mirror-like finish.
Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads. Screws that meet ASTM B456 and ASTM F837 comply with standards for materials.

Phillips Oval Head Screws
These screws have a decorative, domed head that sits above the surface when installed. They're angled under the head so they can be countersunk in a hole. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic. Length is measured from the top of the bevel.
Chrome-plated stainless steel screws have a decorative, mirror-like finish.

Rounded Head Screws with Washer for Sheet Metal
A free-rotating, permanently attached washer distributes holding pressure over a wider area than a flange and remains stationary to prevent scratching the material surface as you tighten the screw. They penetrate 0.025" and thinner sheet metal. Length is measured from the edge of the head. Head height includes the washer.
Chrome-plated steel screws have a bright and attractive finish. They're corrosion resistant in wet environments.

Hinge Screws
Commonly used with door hinge hardware, these screws cut threads in soft material such as aluminum and brass. They're beveled under the head for use in countersunk holes. They are undercut to allow more threading. Screws cut threads in drilled holes as they’re turned, so they require less driving torque and cause less stress on your material than thread forming screws. Length is measured from the top of the head.
Brass, bronze, and chrome-plated steel screws have a bright and attractive finish. They're corrosion resistant in wet environments.

Brass Binding Barrels and Screws for Door Hardware
Brass binding barrels and screws are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. Use them to anchor door closers, kickplates, and other architectural hardware. The barrel head is smooth with no drive to be tampered with on the outside of your door, and the screw has a flat head that sits flush with the surface for a finished look. The screw protrudes from the barrel to leave room for hardware. Install in a hole with a diameter equal to the barrel diameter. Barrel length and screw length are measured from under the head.

Recessed Pull Knobs
