Black oxide Hex Socket Button Head Combination Screws

JINSIXI's Black oxide Hex Socket Button Head Combination Screws are factory-assembled with screws, flat washers and spring washers. The screws provide the main fastening force, the flat washers are located between the surface of the connector and the spring washers, and the spring washers are located between the flat washers and the screw heads. After assembly, the washers will not fall off the screws easily, making it easy to transport, store and use, while saving a lot of assembly time and effort.

Parameter (Specification)

Feature And Application

• Various thread sizes available, including from M3 to M10

• High strength and uniform stress distribution

• 10.9 grade high tensile steel as standard

• Cost effective

Compared to screws without washers, Black oxide Hex Socket Button Head Combination Screws have significant advantages in cost control and assembly time savings, including the following:

• Due to the combined effect of the flat washer and the spring washer, the combined screw exerts greater axial pressure on the connector, so the friction generated is also greater, which can effectively prevent loosening caused by vibration or impact.

• The combined screw eliminates the need to manually insert the flat washer and the spring washer in sequence, which not only simplifies the operation steps, but also effectively prevents the loss and omission of parts, and improves the convenience of storage.

• The flat washer expands the contact area between the screw and the surface of the connector, effectively disperses the pressure, and prevents the combined screw from damaging the coating or finish of the connector surface.

• Only one material, the combined screw, needs to be purchased and managed, instead of three independent materials, screws, flat washers and spring washers, which simplifies the logistics and procurement process, while improving the assembly speed and directly reducing labor costs.

Details

The core value of our own brand JINSIXI's Black oxide Hex Socket Button Head Combination Screws lies in combining excellent anti-loosening performance with extremely high assembly efficiency. At the same time, the oxide film generated by the blackened screws can effectively isolate the screws from direct contact with air and moisture, and has a certain anti-corrosion ability. Although the blackening treatment of the combination screws is low in cost, it has a matte effect, beautiful and uniform appearance, and has almost no effect on the thread accuracy of the screws. Not only that, JINSIXI's Black oxide Hex Socket Button Head Combination Screws processes are relatively environmentally friendly and have a high cost-effectiveness. It is a popular, efficient and reliable fastening solution in the modern manufacturing industry.
