40mm Hinges | McMaster-Carr

These rod end bolts are good for wet and corrosive environments—for maximum mounting flexibility, cut the fully threaded shaft to whatever length you need. Also known as swing bolts and eyebolts, rod end bolts have no moving parts. They're designed to make pivoting or hinge movements in applications that don't need to compensate for misalignment.

Brass rod end bolts resist corrosion in humid and wet environments, but not as well as stainless steel bolts. They're also not as strong. Often, brass bolts are chosen for their look, or to match other components, such as hinges.

303 and 304 stainless steel rod end bolts won't rust in humid, wet, and washdown environments. They're stronger than brass bolts and nearly as strong as steel. They will rust when exposed to salt water and chemicals, however. Black-oxide 303 stainless steel rod end bolts have a matte-black finish that adds some corrosion resistance but is mostly chosen for its looks.

17-4 PH stainless steel rod end bolts have the most tensile strength—a similar amount to high-strength alloy steel. They also won’t rust in humid, wet, and washdown environments. Even at high temperatures, they maintain their excellent strength and corrosion resistance, so they’re often used in automotive drive trains and heat exchangers. However, they’ll rust when exposed to salt water and chemicals.

316 stainless steel rod end bolts are our most corrosion resistant, and they're nearly as strong as steel rod end bolts. Use them in areas with salt water, chlorine, and chemicals without worrying about rust.

ASTM rod end bolts meet a standard for material.

DIN 444 rod end bolts meet an international standard for rod end dimensions.

Partially Threaded Rod End Bolts

Black-Oxide Carbon Steel

Create pivoting connections in applications that require high shear strength—the partially threaded shank of these rod end bolts withstands more side force than a fully threaded shank. Also known as swing bolts and eyebolts, they are used to create hinges, turnbuckles, and tie downs. Unlike ball joint rod ends, these rod end bolts are made from a single piece of metal, so they wear down more slowly and have a more controlled swing. However, because they do not have a moving ball joint, they do not compensate for angular misalignment.

Made from steel, they are stronger and more wear resistant than stainless steel rod end bolts, but they are not as corrosion resistant. Rod end bolts with a black-oxide finish have a dark, matte coating that keeps the steel from rusting in dry environments.

Rod end bolts that meet DIN 444 adhere to international dimensional standards, ensuring they are compatible with other parts and tools.

Corrosion-Resistant Partially Threaded Rod End Bolts

Brass

Stainless Steel

Black-Oxide Stainless Steel

Pivot and hinge components in wet and corrosive environments with these stainless steel or brass rod end bolts. They're commonly known as swing bolts and eyebolts. With no moving parts, they're less likely to wear out than ball joint rod ends, although they don't compensate for misalignment as effectively. Use them to guide and connect components, such as tubing, or as a turnbuckle to tension wire and cable. They can also be used as tie downs and hinges.

With external threads, these bolts hold fast to female threaded components in applications where high shear strength is required, such as water pumps, alternators, and motor mounts. Because the shank is only partially threaded, they handle a greater amount of force from the side than bolts with a fully threaded shank.

303 and 304 stainless steel rod end bolts won't rust in humid, wet, and washdown environments. They're stronger than brass bolts and nearly as strong as steel. They will rust when exposed to salt water and chemicals, however. Black-oxide 304 stainless steel rod end bolts have a matte-black finish that adds some corrosion resistance but is mostly chosen for its looks.

DIN 444 rod end bolts meet an international standard for rod end dimensions.
