Chicago Screws Black Galvanized

Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. It is a processing method that utilizes the plastic deformation of metal under the action of
external forces, and with the aid of molds, redistributes and transfers the volume of metal to form
the required parts or blanks. The cold heading process is most suitable for producing standard
fasteners such as bolts, screws, nuts, rivets, and pins.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.

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.

Applications:

• 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.
