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.

Metric Medium-Strength Steel Threaded Rods—Grade B7
Made of Grade B7 steel, the tensile strength of these threaded rods is one and a half times higher than low-strength steel threaded rods. They also meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

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 High-Strength Steel Threaded Rods—Class 10.9
These Class 10.9 steel threaded rods are about 25% stronger than medium-strength steel rods.

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.
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.
