Alloy Steel Hex Drive Flat Head Screws Grade 8.8 Countersunk Head Machine Screws DIN7991 Flat Head Screws

 

Products Description

 

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.

Screws with an undercut profile have a shallow head for use in thin materials.

Black-oxide alloy steel screws have mild corrosion resistance in dry environments.

Zinc-plated alloy steel screws resist corrosion in wet environments.
