RIFI Factory Price Electrical Zinc Plated Drop-In Anchors M8 M10 M12

Drop-In Anchor is a type of fastener used to provide a secure threaded connection in concrete, masonry, or other solid base materials. It is designed to be installed flush with the surface, making it ideal for applications where a clean, finished look is required. Drop-in anchors are commonly used in construction, HVAC, electrical, and mechanical installations.

Key Features of Drop-In Anchors

1. Design:

   • Cylindrical sleeve with internal threads.

   • Expands when a bolt or threaded rod is inserted, creating a secure hold.

2. Material:

   • Typically made of carbon steel, stainless steel, or zinc-plated steel for corrosion resistance.

3. Installation:

   • Requires pre-drilling a hole in the base material.

   • Installed using a setting tool to expand the anchor.

4. Load Capacity:

   • Designed to handle both tensile (pull-out) and shear (side-load) forces.

Applications of Drop-In Anchors

1. Construction:

   • Securing handrails, guardrails, and structural supports.

   • Anchoring machinery or equipment to concrete floors.

2. HVAC and Electrical:

   • Mounting pipe hangers, conduit supports, or ductwork.

3. General Use:

   • Installing threaded rods for suspended ceilings or lighting fixtures.

   • Fastening fixtures to concrete walls or floors.

Installation Steps

1. Drill a Hole:

   • Use a hammer drill and a carbide-tipped bit to drill a hole of the specified diameter and depth.

2. Clean the Hole:

   • Remove dust and debris using a brush, compressed air, or a vacuum.

3. Insert the Anchor:

   • Place the drop-in anchor into the hole, ensuring it sits flush with the surface.

4. Set the Anchor:

   • Use a setting tool and hammer to expand the anchor, securing it in place.

5. Install the Fastener:

   • Insert a bolt, threaded rod, or other fastener into the anchor and tighten.

Advantages of Drop-In Anchors

• Provides a flush, finished appearance.

• High load capacity for heavy-duty applications.

• Easy to install with the right tools.

• Versatile for use in concrete, brick, or block.

Common Sizes

Drop-in anchors are available in various sizes, typically specified by:

• Thread Size: e.g., 1/4", 3/8", 1/2" (imperial) or M6, M8, M10 (metric).

• Embedment Depth: The depth required for proper installation.
