Anchor screws are specialized screws designed to securely attach objects to surfaces such as walls, concrete, bricks, or other non-wood materials. They are commonly used in applications requiring high load capacity. Below are the details:
1. Structure:
- Screw Body: Made from durable materials like carbon steel or stainless steel, resistant to corrosion and high loads.
- Screw Head: Available in various types (hex, flat, or round) to fit different tools.
- Anchor Mechanism: Some types include an expansion sleeve or mechanism to provide a secure grip.
2. Types of Anchor Screws:
- Expansion Anchors: Use friction to secure screws in pre-drilled holes by expanding.
- Concrete Screws: Create threads in concrete surfaces directly.
- Sleeve Anchors: Include a sleeve that expands for a secure fit.
- Toggle Anchors: Suitable for hollow walls like drywall, using a toggle mechanism.
- Chemical Anchors: Use adhesive or chemicals for maximum load capacity.
3. Applications:
- Fixing shelves, brackets, or heavy equipment to walls or ceilings.
- Used in construction, machinery installation, and outdoor environments.
