Alloy Steel Socket Head Screws


With a tensile strength of 170,000 psi, these alloy steel screws are stronger than Grade 8 steel screws. Length is measured from under the head.
Zinc-plated steel screws resist corrosion in wet environments. The screws with a blue-dyed finish are easy to distinguish.
Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. Screws that meet ASME B18.3, ASME B18.3.1M, ISO 21269, and ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.

Metric Alloy Steel Hex Drive Flat Head Screws

Made from alloy steel, these screws are nearly twice as strong as stainless steel flat head screws. They're angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.
Zinc-plated alloy steel screws resist corrosion in wet environments. Screws with a blue-dyed finish have a distinctive blue color that makes them easy to identify.

Metric Alloy Steel Button Head Hex Drive Screws

These alloy steel screws are nearly twice as strong as stainless steel button head screws. Length is measured from under the head.
Zinc-plated alloy steel screws resist corrosion in wet environments. Screws with a blue-dyed finish have a distinctive blue color that makes them easy to distinguish.
