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.
Black-oxide steel screws are mildly corrosion resistant in dry environments. Zinc-plated steel screws resist corrosion in wet environments.
The screws with a blue-dyed finish are easy to distinguish. Zinc-flake-coated steel screws are 20 times as corrosion resistant as zinc-plated screws and
comparable to Dacromet-coated screws. Zinc-aluminum-coated steel screws are 40 times as corrosion resistant as zinc-plated screws and comparable to Magni-coated screws.
They withstand 1,000 hours of salt spray per ASTM B117.
Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch.
Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance.
They are not compatible with coarse threads.
Screws that meet ASTM A574, ASTM A574M, and ISO 898-1 comply with specifications and testing requirements for material quality.
