Flat head hexagon socket 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.

Flat Head Hexagon Socket Barrel Nuts, also known as socket barrel nuts ou barrel nuts with hex sockets, are specialized fasteners designed for applications requiring a flush or low-profile connection with internal hex drive compatibility.

Caraterísticas principais:

1. Flat Head Design – The top of the nut is flat (countersunk), allowing it to sit flush with or below the surface of the material, providing a smooth finish.

2. Flat head hexagon socket barrel nut

3. Hexagon Socket (Internal Hex Drive) – The nut features a hexagonal recess (like a socket head cap screw) that requires an Allen key (hex key) or a hex driver bit for installation and removal.

4. Barrel Shape – The body of the nut is cylindrical (barrel-shaped), making it suitable for applications where a traditional hex nut may not fit or where rotational stability is needed.

5. Threaded Interior – Contains internal threads to mate with a corresponding bolt or threaded rod.

6. Material & Finishes – Typically made from steel (grade 8.8, 10.9, or 12.9), stainless steel (A2/A4), or brass, with optional coatings like zinc plating, black oxide, or galvanization for corrosion resistance.

Common Uses:

• Aerospace & electronics due to their compact and secure fastening.

• DIY & woodworking projects requiring hidden or recessed nuts.

Sizing & Specifications:

• Available in metric (M3, M4, M5, M6, etc.) and imperial (1/4″, 5/16″, etc.) sizes.

• Thread pitch varies (fine or coarse threads depending on application).
