The Specification of Brass threaded insert

March 31, 2023

Brass threaded inserts are cylindrical metal components that are designed to be inserted into a pre-drilled hole in a variety of materials, including plastic, wood, and metal. These inserts have a threaded interior that allows for the insertion of screws or bolts to securely fasten the material to another surface.

The following are some common specifications of brass threaded inserts:

1. Material: Brass threaded inserts are typically made from high-quality brass, which is known for its strength, durability, and corrosion resistance.

2. Thread size: The size of the thread is an important consideration when selecting brass threaded inserts. The most common thread sizes for these inserts are M4, M5, M6, and M8.

3. Length: The length of the brass threaded insert is determined by the thickness of the material being fastened. The length of the insert should be slightly longer than the thickness of the material to ensure a secure fit.

4. Outer diameter: The outer diameter of the brass threaded insert is also an important consideration. It should be slightly larger than the diameter of the pre-drilled hole to ensure a tight fit.

5. Type of insertion: There are two main types of brass threaded inserts: press-fit and heat-set. Press-fit inserts are inserted into the pre-drilled hole with a press, while heat-set inserts are inserted using heat to melt the surrounding material and allow the insert to be pressed in.

6. Finish: Brass threaded inserts can be finished with a variety of coatings, including nickel, chrome, and black oxide. These coatings provide additional protection against corrosion and wear.

7. Application: Brass threaded inserts are commonly used in a variety of applications, including electronics, automotive, aerospace, and furniture manufacturing. They are ideal for applications that require a strong, secure connection between two materials.
