Corrosion Resistant Hex Zinc Slotted Tail Wood Self Tapping Screw With Washer

Corrosion-Resistant Hex Zinc Slotted Tail Wood Tapping Screws with Washer

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:

1. Enhanced Torque Transmission
