Big Head Screws

Features of Big Head Screws

• Material: These screws are often made from materials like stainless steel, carbon steel, aluminum, or even specialized plastics, depending on their intended use. Stainless steel is favored for its corrosion resistance, making it ideal for outdoor or humid environments.

• Head Design: The enlarged head design can come in various shapes such as truss, button, or flange heads, each providing different aesthetic and functional advantages. The wide head helps in distributing pressure over a larger area, reducing the risk of material damage.

• Drive Types: Big head screws can be equipped with various drive types, including Phillips, flat, Torx, or hex. Each drive type offers different benefits in terms of ease of installation and resistance to cam out.

• Size and Length: While the head is larger, the body of the screw can vary significantly in diameter and length, allowing use in a variety of material thicknesses and for different strength requirements.

Customizable Options: Thread Pitch, Head Diameter, and Drive Types

Our fasteners are fully customizable to meet your project’s unique demands:

1. Thread Pitch (Fine vs. Coarse)

Coarse Threads: Faster installation in soft materials (wood, plastic).

Fine Threads: Higher tensile strength for metal-to-metal applications.

Custom Pitches: Match existing hardware (e.g., M12 x 1.75mm for automotive).

2. Head Diameter (10mm–50mm)

Large Heads: Distribute load across fragile surfaces (carbon fiber, ceramics).

Low-Profile Heads: Save space in compact assemblies (electronics, drones).

3. Drive Types

Phillips/Slotted: Cost-effective for general-purpose use.

Torx (T10–T40): Anti-stripping performance for high-torque applications.

Hex Socket: Tamper-resistant security with Allen keys.

Material Pairing Guide:

Case Study: A robotics company ordered M8 screws with T25 Torx drives and 20mm heads to prevent stripping during high-speed assembly. Cycle times improved by 25%.

How to Order Custom Fasteners

1. Submit CAD drawings or samples.

2. Choose thread type, head size, and drive.

3. Select coatings (e.g., zinc-nickel for aerospace).

4. Approve prototypes before bulk production.
