Industrial Cross Recessed M3-M8 Hex Bolt Zinc Coated Washers

Industrial Cross Recessed M3-M8 Hex Bolt Zinc Coated Washers


1.Products Details:

This assembly is a pre-configured fastening solution combining three components:
1. Cross Recessed Hexagon Head Bolt: Features a hexagonal shank for wrench tightening and a cross-shaped recess (Phillips drive) for screwdriver compatibility, offering dual-tool accessibility.
2. Spring Washer: A helical washer that provides tension and vibration resistance, preventing loosening under dynamic loads.
3. Flat Washer: A thin circular washer placed between the bolt head and the surface, distributing pressure evenly and protecting the material from damage.


2.Key Features:

- Saves time by eliminating separate component handling during installation.
- Spring washer reduces loosening in high-vibration environments (e.g., automotive, industrial machinery).
- Flat washer prevents bolt head indentation on soft materials (e.g., wood, aluminum).
- Hex head + cross recess allow flexibility in installation tools.
