Phillips Hex Head Screws Combination Bolts Spring Flat Double Washer is a bolt with a cross slot, hex head and a combination of spring and flat washers.

Stainless Steel (304/316): Offers superior corrosion resistance and is suitable for moist or corrosive environments. The 316 grade has additional molybdenum, providing even better corrosion resistance, especially in marine applications.

Carbon Steel: Provides good strength and is the most common material for bolts. It may require additional surface treatments like galvanizing for increased corrosion resistance.

Alloy Steel: Offers enhanced strength and durability. It is often used in high-stress applications where high tensile strength is required. 

Advantage:

Anti-loosening performance: spring washers provide additional anti-loosening effect, reducing the risk of loosening due to vibration or impact. Quick Installation: The design of the combination bolt reduces the number of steps required to place separate washers during installation, speeding up assembly. Double Washers: The combination of spring washers and flat washers provides improved support and vibration protection, while also helping to prevent corrosion. HIGH STRENGTH: Usually made of high-strength materials, they are able to withstand large preload forces.

Scope of Application

Mechanical assembly: Used in mechanical equipment to provide a solid connection and anti-loosening effect. Electronic equipment: used in the assembly of electronic equipment to secure circuit boards and other components. Furniture Manufacturing: In the assembly of furniture, to provide a durable and non-loosening connection. Construction industry: In building structures, for connecting structural components to ensure long-term stability.
