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.
Chicago Screws Black Galvanized are heavy-duty, corrosion-resistant fasteners designed for structural and outdoor applications where strength and durability are critical. They combine the rust-resistant properties of galvanization with a black oxide or phosphate finish for enhanced protection and a sleek appearance.
Key Characteristics:
2. Head Design
-
Chicago Head (Hex Washer Head):
-
Low-profile hexagonal head with an integrated washer face.
-
Distributes clamping force evenly, reducing material damage.
-
Prevents cam-out (slipping) when used with power tools.
-
Advantages Over Standard Screws
✅ Dual Protection: Galvanized + black oxide resists rust longer than plain zinc screws.
✅ Stronger Grip: Chicago head prevents stripping under high torque.
Final Verdict:
Chicago Black Galvanized Screws are the go-to choice for contractors and DIYers needing a durable, weather-resistant fastener with a professional look. Whether for metal framing, outdoor builds, or heavy-load applications, they outperform standard screws in both strength and longevity.
-
Head Style:
-
Chicago (or “hex washer”) head – a low-profile hexagonal head with a built-in washer face for better load distribution and grip.
-
Designed to prevent stripping when driving with a power drill or impact driver.
-
Aplicações:
-
Metal stud framing (drywall, HVAC, roofing).
-
Attaching wood to metal (e.g., decking, fencing).
-
Automotive and machinery assembly.
-
General construction where corrosion resistance is needed.
These screws are ideal for projects requiring both aesthetic appeal (black finish) and long-term weather resistance.
