Detailed Product Description

DIN 7991 ISO 10642 UNI 5933 Hexagon Socket Countersunk Head Cap Screws Class 10.9 Black

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.

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.

DIN 7991 Flat Black Zinc M3 To M24 Countersunk Head Screws

Flat head countersunk socket cap screws DIN 7991 are not intended for high strength application. The purpose of producing them with a strength of the property class 10.9 is to increase the wear resistance of the sockets.
