Product Description

Introducing the Concave Cross Hexagon Combination Screw—also known as the Cross Groove Concave Hexagon Head Combination Screw or Cross Groove Hexagon Combination Screw—this fastener is a masterful composition of a cross groove hexagon bolt, a flat washer, and a spring washer. Here is an in-depth exploration of the unique features of the Concave Cross Hexagon Combination Screw:

1. Structural Characteristics

External Hexagon Bolt: Featuring a hexagonal head, this bolt ensures effortless tightening with a wrench or socket. The bolt head includes a cross groove, allowing it to be driven with precision using a screwdriver or power tool.

Flat Washer: Strategically positioned between the bolt and the connecting piece, it expands the contact area, evenly distributes pressure, and safeguards the surface of the connecting piece from scratches or damage.

Spring Washer: Nestled between the flat washer and the bolt, it introduces additional elasticity, effectively preventing the bolt from loosening due to vibrations or impacts.

2. Common Specifications

Boasting a variety of specifications, the concave cross hexagon combination screws come with common thread sizes such as M3, M4, M5, M6, M8, etc. The length spectrum typically ranges from 5mm to 90mm, allowing for tailored specification selection according to connector requirements and installation conditions.

3. Material and Hardness Grade

Material: These screws are available in carbon steel or stainless steel. Stainless steel offers excellent corrosion resistance and robustness, making it perfect for humid or corrosive environments.

• Hardness Level: Carbon steel screws are available in various hardness grades like 4.8 and 8.8. The 8.8 grade signifies high strength and hardness, ideal for applications with substantial load-bearing demands.

4. Applications and Advantages

Widely Used: Concave cross hexagon combination screws find extensive application in mechanical equipment, furniture, electronic devices, automobiles, and more, providing secure and reliable component connections.

Easy Installation: The cross groove enables swift installation using a screwdriver or power tool, greatly enhancing work efficiency.

Reliable Fastening: The combination of flat washers and spring washers significantly boosts the connection's stability and reliability, effectively preventing any loosening.

5. Precautions

• Choose Appropriate Specifications: Accurately select specifications and materials based on the connector requirements and installation environment for optimal performance.

Correct Installation: Ensure that both the flat washer and spring washer are accurately positioned to prevent any misalignment or omission.

Regular Inspection: For long-term equipment usage, routinely check the fastening of connecting parts. Address any signs of looseness by promptly tightening or replacing screws.

In conclusion, the Concave Cross Hexagon Combination Screw is a compact, user-friendly, and dependable fastener, essential for a variety of machinery and equipment. When selecting and utilizing these screws, it's imperative to choose the right specifications and materials based on real-world needs and the installation setting.
