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.
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.

Designed for construction and exterior building applications, these metric screws are often used to join I-beams and scaffolding. Their partial threading leaves an unthreaded portion that is strong enough to stand up to the sideways forces of joints. Made of Class 10.9 steel, these screws are at least 25% stronger than our medium-strength steel heavy hex head screws. They also have a hot-dipped galvanized finish that makes them 10 times more corrosion resistant than zinc plating, so they won't rust in wet environments. However, this finish is thicker than other finishes, so they should be used with DIN 6916 structural washers and DIN 6915 structural hex nuts. All meet ISO 7412 (formerly DIN 6914), an international standard for screw dimensions.

Combine these setup studs with T-slot nuts, flanged nuts, setup clamps, or setup blocks to clamp and hold workpieces, vises, and other objects onto your fixturing table. Also known as double-ended studs, they have threads on both ends. One end threads into a T-slot nut or flanged nut inside the table. The other end passes through a setup clamp and secures with a nut and washer. The middle of the stud is unthreaded for gripping and adjusting the stud.
These setup studs are also used to align parts during assembly. One end of the stud is threaded into the part being added, and the other end fits into the mounting hole of the mating part. Because the studs don't have a head, you have the option to thread them into holes from either end, but they require a nut. You can adjust the distance between the mating parts by tightening and loosening the nut.
Black-oxide steel studs have a protective coating that resists corrosion in dry environments.
