Truss Head Tapping Screw Fasteners JIS B 1122(AAT4) Cross Recessed Nickel Plating

JIS B 1122(AAT4) Cross Recessed Truss Head Tapping Screws Nickel Plating/Galvanization Grade 4

Characteristics:

1. Cross Recessed Design: These screws feature a cross-slot design that ensures stable engagement with screwdrivers, reducing the possibility of slippage during tightening or loosening.

2. Truss Head: The truss head design makes the screw head flatter, allowing for installation in confined spaces while providing a sufficient torque transmission area for the screw to withstand higher tensile forces.

3. Self-Tapping Capability: These screws possess self-tapping properties, enabling them to thread into materials without pre-drilling.

4. Material Versatility: According to the JIS B 1122(AAT4) standard, the screws can be made from various materials such as carbon steel, stainless steel, etc., to suit different application environments and requirements.

Advantages:

1. Ease of Installation: Due to their self-tapping ability, they require no pre-drilling, significantly simplifying the installation process.

2. Efficiency: The cross-slot design allows screwdrivers to engage the screw head more quickly, improving work efficiency.

3. Excellent Biting Performance: The truss head design provides a larger torque transmission area, making the screw more secure when subjected to tensile forces.

4. Good Universality: These screws are suitable for a wide range of materials and installation environments, demonstrating excellent versatility.

Application Scenarios:

1. Furniture Manufacturing: In furniture assembly, these screws are commonly used to connect various components such as boards and frames.

2. Construction Industry: In areas such as building decoration and curtain wall installation, these screws are often employed to fix panels, decorative strips, and other components.

3. Electronics Industry: During the assembly of electronic devices, these screws are also frequently used to secure circuit boards, casings, and other parts.

4. Automotive Industry: In automotive manufacturing and maintenance, these screws can be used to fix interior trim, exterior trim pieces, and more.

5. General Mechanical Assembly: Cross-recessed truss head tapping screws are widely used in the assembly and repair of various mechanical equipment due to their superior performance.
