Products Description
Hexagon Head Screws with Integrated Washer are high-performance fasteners that integrate the functions of a standard hexagon head and a flat washer. They are designed for demanding applications requiring high preload, uniform load distribution, and reliable anti-loosening. Through optimized construction and materials, this product provides a superior connection solution, ensuring assembly integrity, stability, and long-term durability.
Core advantages
| Features | This product (HHS-IW) |
| Assembly Efficiency | Single-piece installation eliminates the possibility of missing washers, saving over 30% of assembly time for Hexagonal Head Screws Featuring Washers. |
| Load Distribution | The integrated washer is optimized for a larger and more even bearing surface for Washer-equipped Hexagon Head Screws, effectively protecting the connected surfaces. |
| Loosening Resistance | The washer and screw head are locked together, preventing relative rotation and providing more stable anti-loosening performance. |
| Conformity | Single-piece production ensures perfect perpendicularity and concentricity between the washer and Hexagonal Head Screws Having Washers. |
Industry Application Cases
Energy Storage Systems
Widely used for battery box structure fixing, module bracket installation, busbar support frame connection, and shell reinforcement. Hexagon Head Fasteners with Built-in WashersHexagonal effectively disperses contact surface pressure, preventing localized damage to aluminum profiles or coated steel plates.
01
Automotive Industry
Hexagonal Head Screws Having Washers are suitable for chassis accessory fixing, battery tray mounting points, power module brackets, and protective plate assembly. The integrated gasket structure improves vibration resistance and reduces preload attenuation caused by driving impacts or thermal expansion and contraction.
02
Construction Engineering
Commonly used in photovoltaic brackets, light steel structure nodes, curtain wall keel installation, and equipment foundation connections. Washer-equipped Hexagon Head Screws can transfer clamping loads over a large contact area, reducing the risk of stress concentration on the surface of steel or aluminum alloy components.
03
Home Appliances
Primarily used for fixing air conditioner compressor bases, motor brackets, washing machine frames, metal shell components, and load-bearing beams. The integrated gasket reduces assembly deformation and improves anti-loosening performance, helping to improve the overall durability test pass rate and transportation reliability.
