Product Description

The cross recessed bolt, often referred to as the cross groove recessed hexagonal head bolt, is a specialized fastener featuring a unique groove and head design. Below is an in-depth look at the cross recessed bolt and its functionalities:

1, Basic Structure

• Head: The bolt's head is hexagonal, ensuring ease of tightening or loosening with a standard socket. This design facilitates quick and efficient application.

• Slot Shape: A cross-shaped recess is expertly designed into the center of the bolt head, accommodating a Phillips screwdriver or a specialized tool for seamless rotational operations.

2, Characteristics and Advantages

Effortless Installation and Removal: The cross groove design ensures swift tightening or loosening with a cross screwdriver, significantly enhancing work efficiency and reducing labor time.

Enhanced Stability: The hexagonal head design increases contact surface with the workpiece, bolstering the connection's stability and reliability, even under demanding conditions.

Versatile Applications: Cross recessed bolts are extensively utilized across various industries, including mechanical equipment, automotive, and aerospace sectors. They are ideal for situations demanding frequent disassembly and adjustment.

3, Specifications and Materials

Specification: These bolts come in a broad range, with nominal diameters typically spanning from M1 to M16, and nominal lengths tailored to specific application requirements.

Material: The choice of materials includes stainless steel, carbon steel, and high-strength alloy steel. Stainless steel boasts excellent corrosion resistance, perfect for moist or corrosive environments. Carbon steel offers a cost-effective solution for dry settings but requires rust prevention. High-strength alloy steel provides superior strength and wear resistance.

4, Surface Treatment

To enhance corrosion resistance and visual appeal, cross recessed bolts often undergo surface treatments like galvanizing, nickel plating, and blackening. Eco-friendly electroplating options, such as colored zinc and blue zinc, are increasingly favored in the market for their environmental benefits.

5, Precautions for Use

• Tool Selection: When working with cross recessed bolts, selecting an appropriate cross screwdriver or specialized tool is crucial. Avoid tools that are improperly sized, as they could damage the bolt head or groove.

• Force Control: It is vital to apply the correct amount of force during bolt tightening to prevent bolt breakage or workpiece damage due to excessive force.

Regular Inspection: Long-term usage warrants regular checks of bolt condition. Any sign of damage or loosening should prompt immediate replacement or re-tightening to ensure continual safety and performance.

6, Related Standards and Testing

Cross recessed bolts are manufactured and tested according to national or industry standards like GB/T 9074.13. These standards dictate requirements for appearance, dimensions, mechanical properties, and outline comprehensive testing methodologies and specifications.

In conclusion, the cross recessed bolt stands as a compact, user-friendly, and stable fastener, indispensable across diverse mechanical and connection scenarios. Users must select suitable tools and apply proper force, coupled with regular bolt inspections, to uphold safety and dependability.
