About Socket Head Screws

Fully Threaded

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-flake-coated steel screws are 20 times as corrosion resistant as zinc-plated screws and comparable to Dacromet-coated screws.

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 B18.3M, ISO 21269, and ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.
