Chicago Screws Black Galvanized

Das Kaltstauchverfahren ist eines der neuen Verfahren für die Druckbearbeitung mit weniger oder gar keiner Zerspanung
Metall. Es handelt sich um eine Verarbeitungsmethode, die die plastische Verformung von Metall unter der Einwirkung von
äußere Kräfte, und mit Hilfe von Formen wird das Metallvolumen umverteilt und in die Form gebracht
die gewünschten Teile oder Rohlinge. Das Kaltstauchverfahren ist am besten geeignet für die Herstellung von Standard
Verbindungselemente wie Bolzen, Schrauben, Muttern, Nieten, Stifte usw.

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.

1. 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.

Anwendungen:

• 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.
