Threaded Rod / Partially Threaded Rod

Stainless Steel Partially Threaded Rod

A partially threaded rod has a thread over part of its length and a plain shank for the rest. It is also sold as a partially threaded stud, or as a rod threaded on one end. The plain shank can act as a guide, a spacer, or a pivot.

The thread can be at one end or at both ends. For a weld-on stud, one end is welded to a base part and the other end carries the thread. Profab Machine makes each rod to your drawing in metric or inch sizes, with left-hand thread when you need it. Rods come in 304, 316L, or 17-4PH stainless steel. Other grades are available on request.

Applications: Marine hardware, food processing equipment, machinery and industrial equipment, and chemical processing equipment.

Why Profab

Your Partially Threaded Rod Supplier

  1. 01

    Made to Your Drawing or Sample

    Send a drawing, a DXF file, or a sample. Our engineers review the dimensions and the tolerance before cutting metal. We CNC machine the part ourselves, so you deal directly with the factory.

  2. 02

    Thread Length to Your Drawing

    You set the thread length, the shank diameter, and the overall length. We CNC machine the rod to that drawing. The thread then ends where your part needs it.

  3. 03

    Grade Matched to the Environment

    The weld zone is the weak point for corrosion on a weld-on stud. For marine air or washdown, 316L is the safer grade. We confirm the grade against your drawing before production.

FAQ

Common Questions

What is a partially threaded rod?

A partially threaded rod has a thread over part of its length and a plain shank for the rest. It is also called a partially threaded stud, or a rod threaded on one end.

How is a partially threaded rod different from all-thread rod?

All-thread rod is threaded along its full length. A partially threaded rod keeps a plain shank, so the shank can act as a guide or a spacer.

What is a weld-on stud?

A weld-on stud has one end welded to a base part. The other end carries the thread, so the stud stands out from the surface with no drilling or tapping.

Does welding affect the corrosion resistance of a stud?

The area around a weld is the weakest point for corrosion. For weld-on studs outdoors, in marine air, or in washdown, 316L is the safer choice.

Should I choose 304 or 316L stainless steel for a partially threaded rod?

Choose 316L where the rod sees salt, chlorides, or chloride-based cleaning chemicals, because it resists pitting better than 304. Choose 304 for indoor, dry, or mildly humid service, where it costs less.

What should I send to quote a partially threaded rod?

Send the thread size and pitch, the thread length, and the shank diameter. Add the overall length, the grade, and the quantity. Say if one end is to be welded. A drawing or a sample speeds up the quote.
