       Product introduction
Stainless Steel Carbon Steel Copper Hexagon Grade8.8 10.9 Combination Bolt
Bolts with washers - a total solution for secure connections
Washer bolt is a kind of industrial standard parts with high strength fastening and efficient protection, which is widely used in machinery manufacturing, automobile industry, construction engineering, electric power equipment and home assembly. Its unique integrated design perfectly combines bolts and washers to provide users with a more convenient and reliable fastening experience.
Product advantage
1. Double protection, double stability
The built-in flat washer effectively disperses the pressure between the bolt head and the connecting surface to prevent the deformation of soft materials or surface scratches; Spring washers (optional) provide continuous elastic compensation to reduce the risk of loosening due to vibration, especially for high frequency vibration environments.
2. Time-saving and efficient, worry-free installation
The preassembled gasket design eliminates the hassle of assembling parts on site, reduces the risk of part loss, significantly improves assembly efficiency, and is ideal for automated production lines and emergency maintenance scenarios.
3. Material diversity, strong adaptability
- Material: 304/316 stainless steel (corrosion resistance), 8.8/12.9 grade alloy steel (ultra-high strength), nylon washer (insulation anti-static).
- Surface treatment: hot dip galvanizing, dacromet coating, electroless nickel plating, to meet the outdoor, chemical, Marine and other extreme environment weather requirements.
4. Parallel standardization and customization
Support ISO, DIN, GB and other international standard specifications, at the same time can be customized non-standard size, shaped gaskets (such as toothed anti-loose gaskets) and special coating, accurately match the needs of special industries such as wind power, rail transit.
Typical application scenario
- Heavy machinery: anti-vibration fastening of key parts of shield machine and crane
New energy vehicles: battery pack bracket anti-loose connection
- Steel construction: anti-fatigue reinforcement of embedded parts of Bridges
- Home decoration: solid wood furniture seamless assembly
Quality commitment
The whole process has passed the ISO 9001 quality management system certification, providing 12 months quality assurance service, professional technical team to support mechanical calculation and selection guidance, to help you achieve zero connection hidden dangers.
