Alloy Steel 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.
