Overview
ROD END STUD Product Overview
This rod end stud fits rod ends with 1/4″ bore and uses a 1/4-28 stud thread. Stud length (L) = 1.031″, shoulder length (N) = 0.562″, shoulder diameter (M) = 0.5″.
Rod end studs allow a rod end to be installed in a plain (non-threaded) bore using a nut to secure the assembly, instead of threading the rod end shank directly into a housing. The stud presses or threads into the rod end body and extends on both sides to provide a pivot pin. Used when the mounting geometry requires a stud rather than a threaded shank, or when mounting two rod ends back-to-back through a common bracket.
Available in carbon steel, alloy steel, and stainless steel. Right-hand thread standard; left-hand (SL suffix) available. Heat-treated alloy steel (SX suffix) available for high-load applications. To order a rod end with stud pre-installed, add ‘S’ to the rod end part number suffix.

ROD END STUD Frequently Asked Questions
What is the 1/4 Rod End Stud used for?
The 1/4 Rod End Stud fits rod ends with a 1/4" bore and lets that rod end be installed in a plain (non-threaded) bore using a nut, instead of threading the rod end shank directly into a housing — the stud presses or threads into the rod end body and extends on both sides to form a pivot pin.
What thread does the 1/4 Rod End Stud use?
The 1/4 Rod End Stud uses a 1/4-28 stud thread, matching the 1/4" bore rod end it's designed for.
What are the length and shoulder dimensions of the 1/4 Rod End Stud?
Stud length (L) is 1.031", shoulder length (N) is 0.562", and shoulder diameter (M) is 0.5".
What misalignment does the 1/4 Rod End Stud allow once installed?
The rod end stud assembly allows approximately ± 25 degrees of misalignment in any direction.
What materials and thread-hand options are available for the 1/4 Rod End Stud?
Available in carbon steel, alloy steel, and stainless steel. Right-hand thread is standard; left-hand is available with an 'SL' suffix, and a heat-treated alloy steel version is available with an 'SX' suffix for high-load applications.
How do I order a rod end with the 1/4 Rod End Stud pre-installed?
Add 'S' to the rod end's part number suffix to order it with the 1/4" stud pre-installed, rather than ordering the stud as a separate item.
