1"-12 Bolts | McMaster-Carr

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—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.

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.

High-Strength Steel

With a tensile strength of 150,000 psi, these rods are strong enough to stabilize steel frameworks and structural supports, such as I-beams. They are about 25% stronger than medium-strength steel rods. To avoid stripped threads during installation, make sure your nuts are also high-strength steel.

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.

Stainless Steel

More corrosion resistant than steel rods and comparable in strength to low-strength steel.

18-8 Stainless Steel—The choice for wet and outdoor environments, these rods resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

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.

With Shoulder—Use for lifting at angles up to 45° or for vertical lifting. Because angular lifting significantly reduces the eyebolt’s capacity, we recommend hoist rings for heavy loads.

Without Shoulder—For vertical lifting only.

Lubrication-Free Ball Joint Rod Ends

A carbon fiber-reinforced insert or PTFE liner reduces wear, handles shock loads, and eliminates the need for lubrication. Made of steel, these rod ends generally handle higher loads than stainless steel, aluminum, and nylon rod ends. All are zinc plated, so they resist corrosion for a short time before the finish is consumed and the steel is exposed.
