ISO4762 Class 12.9 Alloy Steel Socket Head Cap Screws Black Oxide Alloy Steel Socket Head Screws
Products Description
Tighten these screws by turning them to the left; once fastened, they prevent counterclockwise-moving parts from loosening. With a tensile strength of 170,000 psi, these alloy steel screws are stronger than Grade 12.9 steel screws. Their black-oxide finish provides mild corrosion resistance in dry environments. Length is measured from under the head.
Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. Screws that meet ISO4762 (formerly DIN 912) comply with specifications for dimensional standards.
