Product Description

Introducing the concave cross hexagon combination screw, a versatile fastener aptly known as the cross groove concave hexagon head combination screw or cross groove hexagon combination screw. This innovative fastener is meticulously designed and crafted, comprising a cross groove hexagon bolt, a flat washer, and a spring washer for exceptional performance. Below is an in-depth exploration of the features and benefits of the concave cross hexagon combination screw:

1, Structural Characteristics

External Hexagon Bolt: Featuring a robust hexagonal head, this bolt allows for effortless tightening using a wrench or socket. Its head is expertly engineered with a cross groove, facilitating easy driving with a screwdriver or power tool, ensuring a seamless assembly experience.

Flat Washer: Positioned strategically between the bolt and the connecting piece, this washer effectively amplifies the contact area, evenly distributes pressure, and shields the surface of the connecting piece from potential scratches or damage, ensuring longevity and integrity.

Spring Washer: Nestled between the flat washer and the bolt, this component introduces additional elasticity, ensuring the bolt remains steadfastly secure, even amidst vibration or impact, thus maintaining optimal operational stability.

2, Common Specifications

Tailored to diverse specifications, the concave cross hexagon combination screws accommodate a range of thread specifications including M3, M4, M5, M6, and M8. With lengths spanning from 5mm to 90mm, these screws cater to varying connector requirements and installation environments, offering flexibility and adaptability.

3, Material and Hardness Grade

Material: These screws are expertly crafted from either carbon steel or stainless steel. The stainless steel variant offers superior corrosion resistance and robust strength, making it an ideal choice for humid or corrosive environments, ensuring durability and reliability.

• Hardness Level: Carbon steel screws are available in varying hardness levels, such as 4.8 and 8.8. The 8.8 grade boasts exceptional strength and hardness, perfectly suited for applications demanding high load-bearing capacity.

4, Application and Advantages

Widely Used: These screws are indispensable across diverse sectors including mechanical equipment, furniture, electronic devices, and automobiles, providing reliable fixation and connection for numerous components.

Easy Installation: Thanks to the cross groove design, these screws enable swift installation using a screwdriver or power tool, significantly enhancing work efficiency and streamlining operations.

Reliable Fastening: The harmonious combination of flat washers and spring washers bolsters connection stability and reliability, effectively preventing loosening and ensuring secure fastening.

5, Precautions

• Choose Appropriate Specifications: Meticulously select specifications and materials that align with connector requirements and the installation environment, ensuring optimal performance.

Correct Installation: Guarantee the accurate placement of flat washers and spring washers to avoid misalignment or omission, thereby ensuring seamless assembly.

Regular Inspection: Conduct regular checks on the fastening of connecting parts, particularly for equipment subject to prolonged use. Promptly tighten or replace screws upon identifying any signs of looseness, maintaining operational integrity.

In summary, the concave cross hexagonal combination screw exemplifies a compact, user-friendly, and reliable fastening solution, indispensable in a myriad of machinery and equipment settings. Selecting appropriate specifications and materials, aligned with actual needs and installation environments, ensures optimal performance and longevity.
