Product Description

The concave cross hexagon combination screw, often referred to as the cross groove concave hexagon head combination screw or simply the cross groove hexagon combination screw, represents a pinnacle of fastening technology. This ingenious fastener is composed of a cross groove hexagon bolt, a flat washer, and a spring washer, each working in harmony to deliver unmatched performance. Discover the impressive features of the concave cross hexagon combination screw:

1, Structural characteristics

External hexagon bolt: Boasting a robust hexagonal head, this bolt ensures effortless tightening using either a wrench or socket. The innovative bolt head features a cross groove, allowing for easy driving with a screwdriver or power tool.

Flat washer: Strategically placed between the bolt and connecting piece, the flat washer enhances the contact area, effectively dissipates pressure, and shields the connecting piece's surface from scratches or damage.

Spring washer: Nestled between the flat washer and bolt, the spring washer adds crucial elasticity, safeguarding against bolt loosening during vibrations or impacts.

2, Common specifications

Our concave cross hexagon combination screws come in a diverse range of specifications, with thread sizes including M3, M4, M5, M6, M8, and more. Lengths typically range from 5mm to 90mm, ensuring a perfect fit for various connector needs and installation environments.

3, Material and hardness grade

Material: Craft your projects with confidence using concave cross hexagonal combination screws, available in carbon steel or stainless steel. Stainless steel offers excellent corrosion resistance and strength, ideal for humid or corrosive conditions.

• Hardness level: Carbon steel screws are offered in various hardness levels, such as 4.8 and 8.8. Grade 8.8 screws excel in strength and hardness, perfect for demanding applications requiring significant load-bearing capacity.

4, Application and advantages

Widely used: Embrace the versatility of concave cross hexagonal combination screws, a staple in mechanical equipment, furniture, electronics, automobiles, and more, adeptly connecting and securing diverse components.

Easy installation: Thanks to the cross groove, installation is a breeze with a screwdriver or power tool, significantly boosting work efficiency.

Reliable fastening: The combination of flat washers and spring washers fortifies the connection's stability and reliability, effectively preventing loosening.

5, Precautions

• Choose appropriate specifications: Ensure optimal performance by selecting the right specifications and materials tailored to connector requirements and installation environments.

Correct installation: Verify the correct placement of flat and spring washers to avoid misalignment or omission, ensuring a secure connection.

Regular inspection: For long-term use, regularly inspect the fastening of connecting parts. Address any looseness promptly by tightening or replacing screws as needed.

In summary, the concave cross hexagonal combination screw stands as a compact, easy-to-install, and highly reliable fastener, trusted across various machinery and equipment. For optimal results, always select appropriate specifications and materials based on actual needs and installation environments.
