Carbon Steel Galvanized Knurled Drop in Anchor

The Carbon Steel Galvanized Knurled Drop in Anchor is a heavy-duty mechanical expansion anchor designed for secure fastening in concrete, brick, and masonry. It features a knurled body for enhanced grip and a galvanized zinc coating for corrosion resistance, making it suitable for both indoor and outdoor applications.

Key Features:

✅ Material: High-strength carbon steel with hot-dip galvanized finish for durability and rust prevention.

✅ Knurled Design: Textured outer surface improves bonding with concrete, increasing pull-out resistance.

✅ Drop-In Installation: Easy to install by inserting into a pre-drilled hole and setting with a hammer and setting tool.

✅ Internal Threads: Compatible with machine bolts, threaded rods, and other fasteners (metric or imperial).

✅ Flush Mount: Sits flush with the surface for a clean, finished appearance.

Applications:

✔ Anchoring handrails, guardrails, and safety barriers

✔ Securing HVAC equipment, electrical conduits, and pipe supports

✔ Installing machinery, signage, and structural frameworks

✔ Suitable for overhead and vertical mounting in concrete

Installation Steps:

Drill a hole in the concrete to the recommended diameter and depth.

Clean the hole (remove dust using a brush or compressed air).

Insert the anchor (knurled end first) into the hole.

Set the anchor using a setting tool and hammer until flush with the surface.

Thread the bolt and tighten to expand the anchor for a secure hold.

Technical Specifications:

Sizes Available: 1/4", 3/8", 1/2", 5/8", 3/4" (other sizes upon request)

Load Capacity: Varies by size and embedment depth (check manufacturer specs)

Standards: Meets ASTM, DIN, and other industry standards

Advantages Over Alternatives:

🔹 Stronger than plastic anchors for heavy-duty applications

🔹 More corrosion-resistant than plain carbon steel (thanks to galvanization)

🔹 Better grip than smooth-body drop-in anchors due to knurling

Notes:

For high-corrosion environments, consider stainless steel drop-in anchors.

Always follow engineering guidelines for load requirements.
