304 Expansion Screw

A 304 expansion screw, often made from 304-grade stainless steel, is a type of anchor used for securing objects to materials where creating a stable, permanent hold is essential, particularly in concrete, stone, or brick. The "304" designation refers to the type of stainless steel used, which is known for its excellent corrosion resistance and durability, making it ideal for both indoor and outdoor applications.

Choosing the Right Expansion Screw Size and Type

Assess Load Requirements: Determine the weight and stress the expansion screw needs to support to choose one with an appropriate load capacity.

Select the Appropriate Type: Choose the type of expansion screw based on the base material (e.g., sleeve anchors for concrete, wall plugs for drywall, toggle bolts for hollow walls).

Choose the Right Size: Match the diameter and length of the screw to the hole size and depth required for optimal performance and security.

Consider Material Compatibility: Ensure the screw material is suitable for the base material and environmental conditions (e.g., corrosion-resistant special screws for outdoor use).

Follow Installation Requirements: Verify pre-drilling needs and required tools to ensure correct installation and secure holding.
