THREADED STUDS and PLUGS

Threaded studs and plugs are wire rope end fittings used to create secure threaded connection points for aircraft cable, wire rope assemblies, and custom cable applications. These fittings are often used when a cable assembly needs to connect to a clevis, bracket, mounting point, nut, or other cable hardware.

Lexco Cable supplies threaded studs, locking studs, threaded plugs, stainless steel swage studs, carbon steel studs, threaded sleeves, and cable railing threaded terminals for commercial, industrial, architectural, and OEM applications. Options are available for different cable constructions, materials, thread patterns, finishes, and strength requirements. For custom wire rope assemblies, Lexco can help identify the right threaded fitting based on cable diameter, construction, load requirements, environment, and installation needs.

MS21259 Stud:

  • The MS21259 Studs include a wrench flat and inspection hole.  They are UNF thread, SS and hold to breaking strength of 7×7 and 7×19 aircraft cable or rope constructions to 19×7, 6×19 Class IWRC, Class 6×37 Class IWRC.

MS21260 Locking Stud:

  • The MS21260 locking stud shares many characteristics of the MS21259, the main difference is the MS21260 has a shorter thread length.

Threaded Plug:

  • Short overall length
  • Cost-effective
  • Typically machined, swaged, hex
  • Threaded plugs do not necessarily hold 100% wire rope strength.  A pull test is recommended for qualification.  Of this product category, the threaded plugs are the most customizable.

SS Swage Stud:

  • SS swage studs are similar to MS21259.  Notable differences include the type of stainless which is Type 316, thread pattern, UNC.  Also, swage studs do not have an inspection hole.

SS Threaded Stud:

  • SS threaded studs are heavy duty.  Thread size is often twice the corresponding wire rope diameter.
  • They are typically-Type 303 or 304 but can be special ordered in Type 316
  • UNC Thread can be UNF
  • Do not have a wrench flat but can be special ordered
  • Machine swaged, round
  • Longer thread length can be ground by special request
  • Larger sizes also available by special request

Carbon Steel Stud:

  • Are typically plain finish but can be supplied in zinc or galvanized.  Like threaded plugs, the before swage diameter is equal to the nominal thread size.  It’s a good, all-around, heavy duty stud.

Carbon Steel Stud:

  • Have an after swage diameter equal to the nominal thread size.  Because they have a greater wall thickness in the swaging area, they can sometimes have an increased holding strength on strand construction such as 1×19.  These threaded studs are well suited for some of the toughest applications.

Frequently Asked Questions About Threaded Studs and Plugs

What are threaded studs used for in wire rope assemblies?2026-08-06T21:21:40+00:00

Threaded studs are wire rope end fittings used to create a threaded attachment point at the end of a cable assembly. They allow aircraft cable or wire rope to connect with brackets, clevises, mounting plates, nuts, and other cable hardware. They are commonly used in custom wire rope assemblies, industrial cable systems, mechanical equipment, cable railing applications, and OEM cable assemblies.

What is the difference between a threaded stud and a threaded plug?2026-08-06T21:22:14+00:00

A threaded stud typically provides a longer threaded connection and may include features such as wrench flats, inspection holes, or heavier-duty swaging areas. A threaded plug is usually shorter, cost-effective, and more customizable. Because threaded plugs may not always hold 100% of the wire rope’s breaking strength, pull testing is recommended when strength qualification is required.

How do I choose the right threaded wire rope fitting?2026-08-06T21:22:48+00:00

The right threaded wire rope fitting depends on the cable diameter, wire rope construction, material, thread type, finish, load requirement, and application environment. Stainless steel threaded studs may be preferred for corrosion resistance, while carbon steel studs may be used for heavy-duty industrial applications. Lexco can help match the correct fitting to your wire rope or aircraft cable assembly.

Can Lexco Cable provide custom threaded studs or plugs?2026-08-06T21:23:20+00:00

Yes. Lexco Cable can supply custom wire rope fittings, including threaded studs and threaded plugs with specific materials, thread patterns, finishes, swage dimensions, and application requirements. Custom options may include stainless steel, carbon steel, zinc plated, galvanized, UNC, UNF, and other fitting specifications depending on the application.

What information should I provide when requesting a quote for threaded wire rope fittings?2026-08-06T21:24:05+00:00

When requesting a quote, provide the cable diameter, wire rope construction, fitting type, material, thread size, thread pattern, finish, required assembly length, load requirements, and application environment. If available, include drawings, specifications, photos, or part numbers so Lexco can recommend the right wire rope fitting or custom cable assembly.
