Custom Flanged Rounded Head Screws Alloy Steel Stainless Steel

Flanged Rounded Head Screws are a type of fastener featuring a rounded (domed) head with an integrated flange (a flat, washer-like collar beneath the head). The flange distributes clamping force over a wider area, reducing the need for a separate washer. These screws typically have a hex socket (Allen drive), Phillips, or Torx drive for installation.

Materials:

Stainless Steel (304, 316) – Corrosion-resistant, ideal for outdoor, marine, or food-grade applications.
Carbon Steel (Grade 8.8, 10.9, 12.9) – High strength, commonly used in machinery and automotive.
Alloy Steel – Heat-treated for extra durability in heavy-duty applications.
Titanium – Lightweight, high strength-to-weight ratio, used in aerospace and medical fields.
Brass – Decorative and corrosion-resistant, often used in electrical and plumbing.
Aluminum – Lightweight and corrosion-resistant, used in electronics and automotive.

Surface Finishes:

Plain (Uncoated) – Standard for stainless steel and brass.
Zinc Plated – Provides basic corrosion resistance (common for carbon steel).
Black Oxide – Improves wear resistance and reduces glare.
Anodized (Aluminum/Titanium) – Enhances corrosion resistance and aesthetics.
Nickel Plated – Decorative and corrosion-resistant, used in electronics.
Dacromet/Geomet – Advanced anti-corrosion coating for harsh environments.

Common Sizes & Specifications:

(Note: Available in metric and imperial sizes, with coarse or fine threads.)

Applications & Use Cases:

Automotive & Machinery – Securing panels, engine covers, and brackets where vibration resistance is needed.
Electronics & Appliances – Used in washing machines, control panels, and PCB mounts.
Furniture & Cabinetry – Provides a neat, flush finish with built-in load distribution.
Aerospace & Defense – Lightweight fasteners for aircraft interiors and structural parts.
Medical Equipment – Used in surgical tools and devices (often titanium or stainless steel).
Marine & Outdoor Equipment – Stainless steel variants prevent rust in wet environments.
Plumbing & HVAC – Brass or stainless steel screws for pipe clamps and ducting.

Advantages:

✔ Integrated flange – Eliminates the need for a separate washer.
✔ Wide load distribution – Reduces surface damage and improves clamping.
✔ Aesthetic & functional – Rounded head offers a smooth finish while the flange enhances grip.
✔ High torque capability – Hex/Torx drives allow for secure tightening.
