Alloy Steel Stainless Steel Button Head Hex Drive Screws Locking Button Screws

Button Head Hex Drive Screws are a type of fastener featuring a low-profile, rounded head with a hexagonal (hex) socket drive. They are designed to provide a sleek, flush, or slightly protruding finish when installed, making them ideal for applications where a smooth surface is desired. The hex drive allows for high torque application using an Allen (hex) key.

Materials of Button Head Hex Drive Screws:

Stainless Steel (e.g., 304, 316) – Corrosion-resistant, ideal for outdoor or marine environments.
Carbon Steel (Grade 8.8, 10.9, 12.9) – High strength, often used in machinery and automotive applications.
Alloy Steel – Heat-treated for enhanced durability.
Titanium – Lightweight, high strength-to-weight ratio, used in aerospace and medical devices.
Brass – Decorative and corrosion-resistant, used in electrical and plumbing applications.

Surface Finishes of Button Head Hex Drive Screws:

Plain (Uncoated) – Basic finish, typically for stainless steel or brass.
Zinc Plated – Provides corrosion resistance (common for carbon steel).
Black Oxide – Improves corrosion resistance and reduces glare.
Anodized (for Aluminum/Titanium) – Enhances corrosion resistance and aesthetics.
Nickel Plated – Decorative and corrosion-resistant.

Common Sizes & Specifications:

(Note: Metric and imperial sizes are available, with coarse or fine threads depending on application.)

Applications & Use Cases:

Machinery & Automotive – Used in engine components, brackets, and assemblies where a low-profile head is needed.
Electronics & Consumer Devices – Securing PCBs, laptop frames, and smartphone components.
Furniture & Cabinetry – Provides a clean, flush finish in modern furniture designs.
Aerospace & Defense – Lightweight fasteners for aircraft panels and structural components.
Medical Devices – Used in surgical instruments and implants (often titanium or stainless steel).
DIY & 3D Printing – Popular for assembling 3D-printed parts and hobbyist projects.

Advantages:

✔ Low-profile head – Reduces protrusion for a sleek finish.
✔ High torque capability – Hex drive allows for strong tightening.
✔ Versatile materials – Suitable for various environments.
✔ Aesthetic appeal – Smooth, rounded head for a clean look.
