Product Description

Introducing the Concave Cross Hexagon Combination Screw – a versatile and indispensable fastener perfect for your engineering needs. Also called the cross groove concave hexagon head combination screw or the cross groove hexagon combination screw, this remarkable fastener comprises a cross groove hexagon bolt, a flat washer, and a spring washer. Below is an in-depth exploration of this essential screw:

1, Structural characteristics

External Hexagon Bolt: With its hexagonal head, this bolt is designed for easy tightening using a wrench or socket. The bolt head features a cross groove, allowing for seamless driving with a screwdriver or power tool. This design ensures a secure and efficient fastening process.

Flat Washer: Positioned between the bolt and the connecting piece, the flat washer serves a crucial role in expanding the contact area, evenly distributing pressure, and safeguarding the connecting surface from scratches or damage.

Spring Washer: Strategically placed between the flat washer and the bolt, this washer introduces additional elasticity, effectively preventing the bolt from loosening amid vibrations or impacts. It ensures a steady hold in dynamic environments.

2, Common specifications

The concave cross hexagon combination screws come in a variety of specifications. Popular thread sizes include M3, M4, M5, M6, M8, etc., with lengths typically spanning from 5mm to 90mm. The choice of specification should align with connector demands and the intended installation environment.

3, Material and hardness grade

Material: These screws are crafted from either carbon steel or stainless steel. Stainless steel boasts excellent corrosion resistance and strength, making it ideal for humid or corrosive settings.

• Hardness Level: Carbon steel screws come in various hardness levels, such as 4.8 and 8.8. Grade 8.8 screws provide high strength and hardness, perfect for applications requiring significant load-bearing capabilities.

4, Application and advantages

Widely Used: The concave cross hexagonal combination screws find extensive application across mechanical equipment, furniture, electronic devices, automobiles, and more. They offer robust fixation and connectivity for diverse components.

Easy Installation: Thanks to the cross groove, these screws can be rapidly installed with a screwdriver or power tool, significantly enhancing work efficiency and reducing installation time.

Reliable Fastening: The integration of flat washers and spring washers bolsters connection stability and reliability, ensuring a steadfast hold that resists loosening over time.

5, Precautions

• Choose Appropriate Specifications: Ensure the selection of suitable specifications and materials, tailored to the demands of the connectors and the environment of installation.

Correct Installation: Proper placement of the flat washer and spring washer is vital to avoid misalignment or omission during installation, ensuring optimal performance.

Regular Inspection: For equipment undergoing prolonged use, regularly inspect the fastening of connecting parts. Tighten or replace screws promptly if any looseness is detected, maintaining safety and functionality.

In summary, the concave cross hexagonal combination screw is a compact, easy-to-install, and reliable fastener that finds extensive use across a myriad of machinery and equipment. When selecting and using these screws, choose specifications and materials that best suit your specific needs and installation environment, ensuring optimal performance and durability.
