Product Description

Cross Recessed Bolt, a marvel of engineering, known in technical circles as the cross groove recessed hexagonal head bolt, boasts a unique groove shape and head design. Dive into the intricate details of these bolts and discover why they are a vital component in the realm of fastening solutions:

1. Basic Structure

• Head: The hexagonal head of the cross recessed bolt ensures a seamless experience when tightening or loosening with a socket, offering effortless manipulation.

• Slot Shape: Nestled at the center of the bolt head is a distinctive cross-shaped recess, perfectly engineered to accommodate a Phillips screwdriver or specialized tool for smooth rotational operations.

2. Characteristics and Advantages

Easy Installation and Disassembly: The innovative cross groove design enhances efficiency, allowing bolts to be effortlessly tightened or loosened with a cross screwdriver, boosting productivity.

Superior Stability: The hexagonal head design amplifies the contact area between the bolt and the workpiece, ensuring a rock-solid and stable connection.

Broad Applicability: The cross recessed bolts exhibit versatility across industries, spanning mechanical equipment, automotive, aerospace, and beyond, making them ideal for diverse connection scenarios demanding disassembly and adjustment.

3. Specifications and Materials

Specification: The expansive range of cross recessed bolts spans nominal diameters from M1 to M16, with nominal lengths tailored to specific requirements, offering flexibility in application.

Material: Choose from an array of materials like stainless steel, carbon steel, and high-strength alloy steel. Stainless steel ensures exceptional corrosion resistance for humid or corrosive settings; carbon steel offers cost efficiency for dry environments; while high-strength alloy steel delivers superior strength and wear resistance.

4. Surface Treatment

To elevate both corrosion resistance and aesthetics, cross recessed bolts undergo surface treatments such as galvanizing, nickel plating, and blackening. Eco-friendly electroplating options like colored zinc and blue zinc are trending, offering sustainable choices for the modern market.

5. Precautions for Use

• Choose Appropriate Tools: When engaging with cross recessed bolts, select an appropriate cross screwdriver or specialized tool. Avoid mismatched tools to prevent potential damage to the bolt head or groove.

• Control Force: Apply measured force when tightening bolts to avert breakage or damage to the workpiece, ensuring longevity and safety.

Regular Inspection: Periodically assess the condition of cross recessed bolts in use. Promptly replace or tighten any that show signs of damage or looseness to maintain optimal functionality.

6. Related Standards and Testing

Cross recessed bolt production and testing conform to rigorous standards like GB/T 9074.13. These standards set detailed criteria for appearance, size, mechanical properties, and testing, ensuring premium quality and reliability.

In conclusion, cross recessed bolts stand out as compact, user-friendly, and stable fasteners, indispensable across mechanical equipment and diverse connection needs. Proper tool selection, force control, and routine inspections are key to maintaining their unparalleled safety and dependability.
