Corrosion-Resistant Fully Threaded Rod End Bolts


Brass	303 Stainless Steel

Black-Oxide 303 Stainless Steel	304 Stainless Steel

17-4 PH Stainless Steel	316 Stainless Steel

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—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 Stainless Steel and 304 Stainless Steel—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—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—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—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 A193, ASTM A276, ASTM A564, ASTM A582, and ASTM B16—ASTM rod end bolts meet a standard for material.

Swivel-Shaft Rod Ends


Ball Joints	Ball Joints with Set Screw, Nut, Lock Washer

With a ball joint at the top of the shank, these rod ends pivot in the middle of the body instead of in the eyelet. Use them for linear push applications that require movement along the length of the connecting rod. Also known as control swivels, they provide an excellent pivoting connection between light mechanical components while constraining excess play. A Buna-N disc dampens vibration.

Lock Washer, Nut, and Set Screw—Rod ends with set screw, nut, and lock washer have a self-locking set screw and integral nut with lock washer for added holding strength.

Easy-Adjust Clevis Rod Ends


Clevis Rod End

Make quick adjustments to these rod ends by inserting and releasing the clevis pins without the need to bend them into place. Also called yoke-end linkages, they support pivoting movement along one axis when threaded onto shafts, rods, valve pistons, and other assemblies. All are zinc-plated steel for moderate corrosion resistance.

Partially Threaded Rod End Bolts

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.

Black-Oxide Carbon Steel—Rod end bolts with a black-oxide finish have a dark, matte coating that keeps the steel from rusting in dry environments.

Corrosion-Resistant Partially Threaded Rod End Bolts


304 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.

304 Stainless Steel—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.
