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.

Alloy Steel Ultra-Low-Profile Socket Head Screws


Made from alloy steel, these screws are nearly twice as strong as stainless steel ultra-low-profile screws. Their black-oxide finish provides mild corrosion resistance in dry environments. To fit in the tightest spaces, they have a head that's about one-third the height of a standard socket head, but their low profile makes their head weaker. Not recommended for critical fastening applications. Length is measured from under the head.
Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch.

Medium-Strength Metric Class 8.8 Steel Hex Head Screws

These Class 8.8 steel screws are suitable for fastening most machinery and equipment. Dimensions meet ISO (formerly DIN) specifications. Length is measured from under the head.
Zinc-plated steel screws resist corrosion in wet environments. Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch.

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.

Eyebolts—For Lifting

Also known as machinery eyebolts.
Galvanized steel eyebolts have a hot-dipped finish for more corrosion resistance than zinc-plated steel.
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.
