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 B18.3M, ISO 21269, and ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.

Metric Medium-Strength Steel Threaded Rods—Grade B7
These Grade B7 threaded rods 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 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.

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.

Setup Studs
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.
Steel studs are low- or medium-strength carbon steel. With no protective coating, they have poor corrosion resistance. Avoid using them in humid and damp environments.

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.
