Pan Head Chicago Screws

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.

Pan Head Chicago Screws (also known as sex bolts, binding posts, or barrel nuts) are a type of two-part fastener consisting of a male screw (threaded bolt) and a female barrel nut (threaded sleeve). They are designed to securely join materials together without the need for a traditional nut on the backside.

Caraterísticas principais:

• Pan Head Design – The screw has a slightly rounded, low-profile head with a flat bearing surface, providing a smooth finish while distributing pressure evenly.

• Internal Threading – The barrel nut (female component) has internal threads that accept the male screw, creating a flush or semi-flush fastening.

• Secure Fastening – Unlike standard screws and nuts, Chicago screws remain tightly fastened, reducing loosening from vibration or movement.

• Non-Protruding Back – The barrel nut sits inside a pre-drilled hole, leaving a clean finish on both sides of the assembly.

Common Materials:

• Aço inoxidável (rust-resistant, durable)

• Brass (corrosion-resistant, decorative)

• Aluminum (lightweight, non-magnetic)

• Nylon/Plastic (non-conductive, lightweight)

Aplicações:

• Leathercraft (belts, holsters, bags, saddles)

• Furniture & Cabinetry (chairs, panels, modular systems)

• Bookbinding & Albums (swatch books, sample binders)

• Industrial & Machinery (panels, covers, fixtures)

• Signage & Displays (secure yet removable fastening)

Pan Head Chicago Screws are ideal for applications requiring a strong, flush-mount fastener with a professional appearance. They are widely used in industries where traditional nuts and bolts are impractical.
