Versatile Size Assortment: Includes 25 pieces each of M4-20, M4-25, M5-25, and M6-25 sizes, providing a comprehensive solution for various installation projects and reducing the need for multiple purchases
Durable Coated Material: Made of carbon steel with zinc-plated silver finish, offering enhanced resistance to rust and corrosion for reliable performance in different environments
Tool-Compatible Installation: Designed for both manual and pneumatic tools, the installation process involves securing the petal nut in the pre-drilled hole to prevent rotation, then threading in the matching screw. Use a wrench or pliers to tighten the assembly; as the screw turns, the nut expands and locks securely in place. Avoid over-tightening to prevent thread stripping
Expansion Locking Mechanism: Unlike standard screws, these nuts expand as the screw is tightened, creating a broader anchoring surface within hollow materials for increased stability
Multi-Material Compatibility: Suitable for plastic, composite wood, hollow walls, and metal sheets, making them ideal for license plate mounting and various hollow wall installations
