Slotted barrel nut

O processo de encabeçamento a frio é um dos novos processos para a maquinagem sob pressão com menos ou nenhum corte
metal. É um método de processamento que utiliza a deformação plástica do metal sob a ação de
forças externas e, com a ajuda de moldes, redistribui e transfere o volume de metal para formar
as peças ou os espaços em branco necessários. O processo de encabeçamento a frio é o mais adequado para a produção de
elementos de fixação, tais como cavilhas, parafusos, porcas, rebites, cavilhas, 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.
