What is a threaded bushing?

A threaded bushing is a fastener assembled to add a hole to make a solid and durable bolted connection. Often, steel is used for threaded bushings, including stainless steel and metal alloys, such as brass. In the case of threaded bushings made of steel, it is practiced to protect them additionally with galvanizing. 

This helps strengthen the corrosion resistance of the components, which increases the durability and safety of the connections created with them. The standard designation of threaded bushings is as follows: M5 x 0.8, where “M” indicates the type of thread (here: metric), “5” – is the nominal diameter, and 0.8 – is the pitch of the thread.

What are threaded bushings used for?

Threaded bushings often create new, powerful connections in wood, plastics, or metals like steel and brass. In addition, threaded bushings can be used to repair damaged threads (self-tapping sleeves manufactured at Sabner are excellent for this) and to change threads from inch to metric and vice versa.

However, making an effective threaded connection in some materials is possible only. This may be due to the material’s properties – brittleness or too much softness, but also the shape of the material. For example, creating a practical and durable threaded connection in very thin sheet metal is very difficult.

Types of threaded sleeves

At Sabner, we manufacture threaded bushings of various types. They are widely used in leading industries because they meet the highest technical and quality requirements. Below are our most important products of this type:

  • Threaded bushings for screwing – they are designed most often as self-tapping sleeves for repairing broken threads or creating a screw connection in materials with low shear strength, such as aluminum and its alloys, brass, bronze, cast iron, plastics, or wood. They are mainly manufactured from steel and stainless steel.
  • Threaded bushings for pressing – have internal threads and often an anchor profile (such as serrations) on the outside. They are great for pressing into thermoplastic materials. Nevertheless, they can be pressed into a pre-drilled, matched hole and tapped. It is manufactured mainly from steel and stainless steel.
Installation of brass sleeves
  • Threaded bushings for overmolding – they are used for molded or cast parts. They have a through thread or a blind hole, as well as thin walls, which also allows them to be used directly on the edges of molded parts. Brass is most often used for their manufacturing.
  • Threaded bushings for welding – used mainly in manufacturing industrial tanks to mount liquid level indicators, filler, drain, or vent plugs. The right shape ensures easy fitting and welding to the structure.

Manufacturing of the highest quality

At Sabner, we manufacture threaded bushings from high-grade steel or brass per customer requirements. We can manufacture and deliver threaded bushings with diameters up to phi 32 to the designated location according to the specifications provided by our customers.
