Alloy Steel Socket Head Screws
Fully Threaded
Partially 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-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. Screws that meet ASME B18.3, ASME B18.3M, ISO 21269, and ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.

Aluminum Socket Head Screws
Fully Threaded
Partially Threaded
Aluminum screws are one-third the weight of steel and have good corrosion resistance. Length is measured from under the head.
Screws with a blue-anodized finish are easy to distinguish.
Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.

Aluminum Ultra-Wide Flanged Button Head Screws
Aluminum screws are lightweight and resist corrosion in wet environments. These screws have a flange that is wider and thicker than our other flanged screws, so they distribute pressure the best. Head height includes the flange. Length is measured from under the flange.

Metric Aluminum Ultra-Wide Flanged Button Head Screws
Made from aluminum, these screws are lightweight and resist corrosion in wet environments. The flange is wider and thicker than our other flanged screws, so they distribute pressure the best. Head height includes the flange. Length is measured from under the flange.
