Eye Bolts

Eye bolts are threaded fasteners with an integrated eye connection point for equipment, hardware, maintenance, fabrication, and assembly work. Commercial buyers use them where a compatible threaded mounting location and an eye-style attachment point are needed as part of an assembly.

Use Cases

Add an eye connection point

Use an eye bolt when an equipment, hardware, maintenance, fabrication, or assembly setup requires an eye-style connection point at a compatible threaded location.

How to Choose

Start with thread compatibility

Match the thread designation to the receiving location or mating component. Available examples include inch threads such as 5/16-18, 3/8-16, 1/2-13, 5/8-11, 3/4-16, and metric threads from M6 x 1.00 through M22 x 2.50.

Applications

Plan around the assembly

Maintenance crews, fabricators, shop teams, and commercial hardware buyers can select a shoulder eye bolt for compatible threaded equipment and hardware assemblies.

Planning Guide

Plan the right fit before choosing

Thread and fit

Confirm the thread before selecting

The thread is the primary fit factor. Choose an inch-thread eye bolt only for a matching inch-threaded location, or select a metric option for a compatible metric-threaded component. Listed thread forms include UNC-2A and UNF-2A on selected inch sizes.

  • Match the nominal thread size and pitch or threads-per-inch.
  • Confirm whether the assembly calls for an inch or metric thread.
  • Check the listed thread class when it is specified for the application.
Shank and pattern

Choose the shank length and shoulder configuration

The represented products use fully threaded shanks, allowing engagement along the shank length. Where a shank length is listed, compare it with the installation requirement; available examples range from 1-1/8 in. to 6 in. Shoulder-pattern eye bolts are represented across both inch and metric thread selections.

  • Select the stated shank length required for the installation.
  • Use a shoulder-pattern configuration when that is specified for the assembly.
  • Review the full-threaded shank requirement for the intended mounting location.
Material and finish

Match the listed construction to purchasing requirements

Drop-forged carbon steel is the primary construction represented in this category. Some carbon steel eye bolts have galvanized, zinc-plated, or self-colored finishes, while one represented shoulder eye bolt is made from 316 stainless steel and has a passivated and electropolished finish. One carbon steel option identifies ASTM A489.

  • Compare carbon steel and 316 stainless steel construction options.
  • Select galvanized, zinc-plated, self-colored, or passivated and electropolished finishes only when specified.
  • Use the ASTM A489 listing as an identification detail for the applicable represented option.
