1 1/4"-12 Bolts | McMaster-Carr

High-Strength Fastener—Commonly used to fasten components in valves, pumps, motors, and other high-stress applications. These screws have a tensile strength of 125,000 to 160,000 psi.

Zinc-Yellow-Chromate-Plated Steel—With slightly better corrosion resistance than zinc-plated steel screws, these stand up to more frequent exposure to moisture.

Steel—Unfinished steel screws are best for dry environments, since moisture will cause them to rust. They require little surface prep before applying a finish, so you can apply your own paint or coating.

Steel Socket Head Screws

Fully Threaded

Partially Threaded

Made of alloy steel, these screws are the standard for high-strength fastening. Use them in high-load applications such as dies, presses, and heavy equipment. The deep, six-point socket keeps the hex key from slipping out and damaging the drive.

Length is measured from under the head.

Black-Oxide Alloy Steel—Best for dry environments since moisture will cause these screws to rust. They have a dark, matte appearance.

Threaded Rods

Anchor, connect, or hang components in a wide variety of applications, from mounting I-beams to suspending light fixtures.

Medium-Strength Steel

Image of Product. Front orientation. Threaded Rods. Threaded Rods.

With tensile strengths from 110,000 psi to 125,000 psi, these rods are strong enough for most industrial applications, such as anchoring machinery and connecting pipe flanges. They are about twice as strong as low-strength steel rods. To avoid stripped threads during installation, make sure your nuts are also medium-strength steel.

Zinc-Yellow-Chromate-Plated Steel—The most common choice for areas with occasional exposure to moisture.

Steel—Best for dry environments since moisture will cause these rods to rust.

Low-Strength Steel

With a tensile strength of 50,000 psi or 60,000 psi, these rods are often used to suspend light fixtures, cable trays, and conduit from ceilings. They're about half the strength of medium-strength steel rods. To avoid stripped threads during installation, make sure your nuts are also low-strength steel.

Steel Hex-Drive Flat Head Screws

Our strongest hex-drive flat head screws. They're made of alloy steel, so they have nearly twice the tensile strength of other screws. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver without slipping and stripping the drive.

Length is measured from the top of the head.

Black-Oxide Alloy Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

Eyebolts—For Lifting

Create a secure attachment point for hooks, shackles, and other lifting equipment. Also known as machinery eyebolts, these eyebolts are used to lift heavy machines and materials. They have a closed eye that won’t bend under strain.

Warning: Never use to lift people or items over people. Capacities listed are for vertical lifting only.
