Machined Black Oxide

Machined black oxide rod ends are threaded hardware components with an eye-end connection point and a fully threaded shank. They are used in commercial maintenance, fabrication, machining, metalworking, and hardware assemblies where a compatible threaded connection and attachment point are required.

Use Cases

Create threaded attachment points

These rod ends are intended for compatible threaded assemblies requiring an eye-end connection point. Common represented uses include maintenance, fabrication, metalworking, machining, and hardware assembly work.

How to Choose

Match thread and shank length

Select the listed UNC-2A thread size that matches the mating component, then compare the available shank length for the needed installation and positioning range.

Applications

Support eye-end assembly arrangements

Eye-end designs provide an attachment point at the end of the threaded component for applicable linkage, fastening, and connection arrangements.

Planning Guide

Plan the right fit before choosing

Start with fit

Confirm the thread specification

Thread compatibility is the first consideration for a rod end. The available products span several UNC-2A thread sizes, so compare the thread designation on the existing mating component with the product listing before selecting.

  • Available listed thread sizes include 1/4-20, 5/16-18, 3/8-16, 1/2-13, 5/8-11, 3/4-10, 7/8-9, and 1-8.
  • Each represented option has a fully threaded shank.
  • Use the stated thread size and class to match compatible threaded components.
Plan the installation

Choose the shank length needed for the assembly

Shank length affects the threaded engagement and positioning available during installation. Compare the listed length with the assembly requirement rather than choosing by thread size alone.

  • Represented shank lengths range from 1-1/2 inches to 6 inches.
  • 5-inch and 6-inch options are available in multiple thread sizes.
  • Fully threaded designs allow engagement along the shank length.
Review construction

Compare carbon steel and 4140 alloy steel listings

Construction varies across the represented products. Carbon steel rod ends are listed as drop forged, while 4140 alloy steel rod ends are listed as forged and, in several cases, heat treated to ASTM A193-B7.

  • All represented options have a machined black oxide finish.
  • Eye-end configurations provide the connection point at the end of the rod end.
  • Some listings state an effective minimum order of one each.
