White Zinc Plated Flat Head Socket Drive Machine Screws Countersunk Head Hex Drive Screws
Products Description
Made from class 10.9 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.
Black-oxide alloy steel screws have mild corrosion resistance in dry environments.
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.
