Slotted barrel nut

Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. It is a processing method that utilizes the plastic deformation of metal under the action of
external forces, and with the aid of molds, redistributes and transfers the volume of metal to form
the required parts or blanks. The cold heading process is most suitable for producing standard
fasteners such as bolts, screws, nuts, rivets, and pins.etc

Slotted Barrel Nuts are specialized fasteners used in various mechanical and structural applications. Here’s a detailed description:

Features & Design:

1. Shape & Structure

   • Barrel-shaped body (cylindrical) with internal threads.

   • Longitudinal slots (cuts) along the sides, allowing slight compression for a tight fit.

   • Typically made from steel, stainless steel, or brass for strength and corrosion resistance.

   • Slotted barrel nut

2. Threading

   • Internally threaded to accept a bolt or screw.

   • Threads may be metric or imperial, depending on application.

3. Slots (Key Feature)

   • Multiple slots (usually 2–4) allow the nut to compress slightly when tightened.

   • Enhances grip in pre-drilled holes or when used with mating fasteners.

Common Uses:

• Furniture assembly (especially flat-pack or modular designs).

• Aerospace & automotive applications where vibration resistance is needed.

• Machinery & equipment requiring secure fastening in tight spaces.

Installation:

1. Insert the barrel nut into a pre-drilled hole or mounting bracket.

2. Align the bolt/screw with the internal threads.

3. Tighten to compress the slotted sides, creating a firm hold.

4. Slotted barrel nut

Variations:

• Flanged Slotted Barrel Nuts – Have an added flange for better load distribution.

• Knurled Barrel Nuts – Exterior texture for hand-tightening in low-torque applications.

These nuts are ideal for applications requiring quick assembly, disassembly, and secure fastening in confined spaces.
