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-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.

Metric Threaded on Both Ends Studs

Also known as setup studs, these studs withstand sideways forces better than fully threaded studs because they have an unthreaded middle that is stronger than the treaded ends. The unthreaded middle also makes more contact with unthreaded holes, which creates better alignment than a fully threaded stud.

Eyebolts—For Lifting

Also known as machinery eyebolts.
Zinc-plated steel eyebolts offer good corrosion resistance.
Galvanized steel eyebolts have a hot-dipped finish for more corrosion resistance than zinc-plated steel.
316 stainless steel are the most corrosion resistant eyebolts.
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.

Rotating Eyebolts—For Lifting

Unlike conventional eyebolts, you can rotate the eye 360° to match the angle of your load.
Powder-coated steel eyebolts are impact resistant, but less corrosion resistant than stainless steel eyebolts. They include a removable key for tightening the bolt.
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.

Eye Nuts—For Lifting


Create your own lifting eye by adding an eye nut to a stud or bolt.
304 stainless steel eye nuts are more corrosion resistant than galvanized steel.
Note: Capacity applies to the eye nut only. The stud or bolt you use will affect the overall capacity. Eye nuts are for vertical lifting only.
