Eyebolts

Eyebolts—For Lifting

Also known as machinery eyebolts.

Eyebolts with Nuts—For Lifting

Also known as nut eyebolts, these are designed for through-hole applications.

Rotating Eyebolts—For Lifting

Unlike conventional eyebolts, you can rotate the eye 360° to match the angle of your load.

Nylon-Coated Eyebolts—For Lifting

Route wire and cable through the smooth eye without snagging.

Low-Visibility Eyebolts—For Lifting

The matte black-oxide finish won't reflect light, allowing the eyebolts to blend into the background.

Low-Temperature Eyebolts—For Lifting

These eyebolts retain their strength in temperatures as low as -40° F.

Routing Eyebolts—Not for Lifting

Use these eyebolts for routing wire and for other light duty applications.
