Use Cases

Assembly, replacement, and service

These fittings are intended for assembling turnbuckle components, replacing an existing fitting, or servicing compatible turnbuckle arrangements.

How to Choose

Match threads first

Confirm whether the assembly requires right-hand or left-hand threading, then match the stated thread size and UNC-2A thread classification.

Applications

Choose the needed end style

Select a stub when a threaded connection point is needed, or select an eye fitting when the assembly requires an eye-end connection point.

Planning Guide

Plan the right fit before choosing

Start with compatibility

Identify the thread direction and size required

Turnbuckle assemblies can require fittings with opposite thread directions. Right-hand and left-hand options are both represented, so matching the existing or specified connection direction is an essential first step. After confirming direction, compare the stated thread size and UNC-2A classification with the compatible hardware.

  • Right-hand options are available in 1/4-20, 3/8-16, 5/8-11, and 3/4-10 sizes.
  • Left-hand options are available in 1/4-20, 5/8-11, 3/4-10, and 1 in.-8 sizes.
  • Several products specify UNC-2A threads for compatibility checks.
Select the fitting form

Choose between a stub and an eye end

Stubs provide a threaded connection point for turnbuckle assemblies. Eye fittings provide an eye-style attachment point while also supplying a right-hand or left-hand threaded end. Select the form that matches the connection required in the turnbuckle setup.

  • Stubs are offered with right-hand and left-hand threads.
  • Eye fittings are offered with right-hand and left-hand threads.
  • Eye-end designs provide an eye connection point in compatible assemblies.
Review physical details

Compare length, construction, and finish

Listed lengths vary by fitting, so review the product dimensions for the assembly or replacement requirement. Stub options are described in mild carbon steel, while eye fittings are described in drop-forged carbon steel. Some fittings have a galvanized finish, and a left-hand 3/4-10 stub is listed with a self-colored finish.

  • Listed stub lengths include 5-1/4 in., 5-1/2 in., 8 in., 9 in., and 11 in.
  • Listed eye lengths include 4 in., 4-1/8 in., 4-9/16 in., and 4-7/8 in.
  • Galvanized options include selected left-hand stubs and right-hand or left-hand eye fittings.
