Product Description

Step into the world of unparalleled fastening with our Concave Cross Hexagon Combination Screw, also known as the Cross Groove Concave Hexagon Head Combination Screw or Cross Groove Hexagon Combination Screw. This marvel of engineering is a sophisticated blend of a cross groove hexagon bolt, a flat washer, and a spring washer. Here's an in-depth look into the features that make this fastener a standout solution:

1, Structural Characteristics

External Hexagon Bolt: Designed with a distinctive hexagonal head, this bolt is a breeze to tighten with either a wrench or socket. The head features a cross groove, allowing for effortless driving using a screwdriver or power tool, combining practicability with efficiency.

Flat Washer: Strategically positioned between the bolt and the connecting piece, the flat washer is instrumental in increasing the contact area, dispersing pressure, and safeguarding the connecting piece's surface from any potential damage or scratches.

Spring Washer: Nestled between the flat washer and the bolt, the spring washer introduces an element of elasticity, effectively preventing the bolt from loosening amidst vibrations or impacts, ensuring steadfast reliability.

2, Common Specifications

Diverse Specifications: Our concave cross hexagon combination screws are available in an array of thread specifications, such as M3, M4, M5, M6, M8, and beyond, with lengths ranging typically from 5mm to 90mm. The choice of specification is dictated by the connector's demands and installation conditions.

3, Material and Hardness Grade

Material: Crafted from either carbon steel or stainless steel, these screws offer both robustness and corrosion resistance. Stainless steel variants excel in humid or corrosive settings, ensuring long-lasting performance.

• Hardness Level: Carbon steel screws boast various hardness grades, notably 4.8 and the highly resilient 8.8. The latter, with its exceptional strength and hardness, is ideal for applications necessitating the support of substantial loads.

4, Application and Advantages

Versatile Applications: These screws are quintessential in mechanical equipment, furniture, electronics, automobiles, and more, providing a reliable solution for securing and connecting diverse components.

Effortless Installation: The cross groove design ensures quick and efficient installation using screwdrivers or power tools, significantly boosting work productivity.

Secure Fastening: The integration of flat and spring washers enhances the connection's stability and reliability, effectively preventing any loosening.

5, Precautions

• Appropriate Selection: It's paramount to select the right specifications and materials tailored to the connector's requirements and environmental conditions.

Proper Installation: Correct placement of the flat washer and spring washer is crucial to avoid misalignment or potential omissions.

Routine Inspection: For equipment subjected to prolonged use, regular checks of the fastening connections are advisable. Any detected looseness warrants immediate tightening or replacement of screws.

In essence, the Concave Cross Hexagonal Combination Screw is a masterclass in compact, easily installable, and dependable fastening technology. It's a go-to choice across machinery and equipment sectors. When selecting and utilizing these screws, consider the specific needs and environmental factors to ensure optimal performance.
