Alloy Steel Socket Head Screws
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 and 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 B18.3.1M, ISO 21269, and ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.

Medium-Strength Steel Threaded Rods—Class 8.8
An economical alternative to Grade B7 and Grade B16 threaded rods, these metric Class 8.8 rods are suitable for fastening most machinery and equipment.
Zinc-plated steel threaded rods resist corrosion in wet environments.

Metric Low-Strength Steel Threaded Rods
These threaded rods are about half the strength of medium-strength steel threaded rods for light duty hanging, mounting, and fastening.
Zinc-plated steel threaded rods are corrosion resistant in wet environments.

Setup Studs
Secure setup clamps and fixtures to your machine table, or assemble heavy machines, such as engine mounts. These studs act as a pilot when connecting parts since they’re headless, which eases installation. Unlike a bolt, which has a head, they let you access parts from either end, but they require nuts to hold the part. Pair them with a T-slot or flanged nut when securing to a machine table. Or, put a nut on before your part to work as a float, allowing you to adjust the height of your part. The unthreaded middle is useful for gripping and adjusting. Also known as double-ended studs.
Steel studs are stronger than stainless steel studs. But, unfinished steel studs will rust from air and moisture.

Eyebolts—For Lifting
Also known as machinery eyebolts.
Zinc-plated steel eyebolts offer good corrosion resistance.
Note: Capacities listed are for vertical lifting only. Eyebolts with shoulder can be used for angular lifting up to 45°, but the capacities will be significantly reduced. For angular lifting, we recommend Hoist Rings.
Warning: Never use to lift people or items over people.
