Product Description

Cross recessed bolts, alternatively known as cross groove recessed hexagonal head bolts, are distinguished by their unique grooved shape and head design. Let us delve into a comprehensive description of this remarkable fastening solution:

1, Basic Structure

• Head: Featuring a hexagonal head, these bolts are designed for seamless tightening or loosening using a socket, offering convenience and efficiency.

• Slot Shape: The bolt head boasts a central cross-shaped recess, perfectly designed to accommodate a Phillips screwdriver or specialized tool, enabling smooth rotational operations.

2, Characteristics and Advantages

Effortless Installation and Disassembly: Thanks to the cross groove design, these bolts can be swiftly tightened or loosened with a cross screwdriver, thereby optimizing work efficiency.

Enhanced Stability: The hexagonal head design significantly enlarges the contact area between the bolt and the workpiece, ensuring a more stable and secure connection.

Versatile Applicability: Cross recessed bolts find extensive applications across various fields, including mechanical equipment, automobiles, and aerospace, ideally suited for connections necessitating disassembly and adjustments.

3, Specifications and Materials

Specification: These bolts offer a broad specification range, with nominal diameters typically spanning from M1 to M16, and lengths tailored to meet specific requirements.

Material: Predominant materials include stainless steel, carbon steel, and high-strength alloy steel. Stainless steel is renowned for its excellent corrosion resistance, ideal for humid or corrosive settings. Carbon steel, while cost-effective, is best for dry conditions due to rust susceptibility. High-strength alloy steel offers superior strength and wear resistance.

4, Surface Treatment

To enhance corrosion resistance and visual appeal, cross recessed bolts often undergo surface treatments, such as galvanizing, nickel plating, or blackening. Eco-friendly electroplating options, like colored zinc and blue zinc, are gaining traction in the marketplace.

5, Precautions for Use

• Select Appropriate Tools: When handling cross recessed bolts, ensure the use of a correctly sized cross screwdriver or specialized tool. Avoid tools that may be too large or small to prevent damage to the bolt head or groove.

• Control Force: Exercise control over the force exerted when tightening bolts to prevent excessive force that could lead to bolt breakage or workpiece damage.

Regular Inspection: Periodically inspect the condition of cross recessed bolts used over extended durations. Replace or tighten any bolts exhibiting damage or looseness promptly to maintain safety and reliability.

6, Related Standards and Testing

The manufacturing and testing of cross recessed bolts adhere to pertinent national or industry standards, including GB/T 9074.13, which outline requirements for bolt appearance, size, mechanical properties, and detailed testing methods.

In summary, the cross recessed bolt stands as a compact, easily installable, and stable fastener prevalent in diverse mechanical equipment and connection scenarios. Remember to choose suitable tools, apply appropriate force, and conduct regular inspections to uphold their safety and reliability.
