High Strength Hex Bolt With Lock And Plain Washer Assemblies
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.
